Fuel supply system for engines of the YaMZ-530 CNG family.

Model history

Throughout the first decade of the 2000s, every year it became more and more obvious that the huge commercial success of Gazelle cars in the Russian and CIS markets would not last forever. Gazelle has plenty of competitors in the field of light-duty business vehicles, and they all have something to interest a potential buyer.

The price factor no longer always became the most important and determining factor when purchasing, especially since the car lending system has developed extraordinary over the years, and loans began to be issued to almost “everyone.” And buyers have become more picky, able to compare and contrast, and are ready to overpay for comfort and reliability in operation, and increased profitability. Therefore, “Gazelle” gradually lost its position, being forced out of the market by more expensive, but also more modern imported “classmates”.

A “response move” in this situation could only be the launch of mass production of a new car, corresponding in quality to modern “classmates” (such as Mercedes Sprinter, Peugeot Boxer, Volkswagen Crafter, Ford Transit, Fiat Ducato ", etc.) But at the same time having a more attractive price!

Meanwhile, the new family may not have reached the assembly line, which has happened more than once with other developments by domestic designers. The following course of action was considered: not to go into the business of creating your own model, which requires enormous capital investments and hassle, but simply assemble the previous generation Mercedes Sprinter at GAZ facilities.

However, even with the highest level of localization, the German light-duty vehicle turned out to be by no means cheap, and in no way falls into the rank of a “budget” car. Domestic consumers, for the most part, should be given a simple frame car (the Sprinter has a monocoque body), which can be overloaded regularly and without serious consequences, and all sorts of minor repairs can be carried out, as they say, “on the knee”, without taking a long break from workflow.

To prepare for the release of the new model, the Gorky Automobile Plant carried out a large-scale modernization of production. The total investment in the Gazelle Next project amounted to almost nine billion rubles.

To produce the new model of the all-metal GAZelle Next van, new automated welding and stamping complexes were created at the Gorky Automobile Plant sites, the painting production and assembly line were modernized.

The automated stamping line is equipped with the latest multifunctional six-axis robots of the latest generation and presses with imported stamping equipment specially made for the project. The line produces large parts, including side panels, bases, sliding and swing doors.

The new welding line allows automatic production of bodies of various modifications. Modern Fanuc robots with a lifting capacity of up to 700 kg are installed in the welding areas of the sidewalls, base, body and door assembly-welding. Each robot, independently changing equipment, is capable of performing operations such as transporting parts, welding, flanging, and applying adhesives and sealants. The welding line also includes new overhead push conveyor routes and automated components supply systems.

Following the basic flatbed version and the universal chassis, other “Gazelle Next” followed: in March 2014, serial production of a truck with a seven-seat double cabin and a bus with a frame-panel body in urban and intercity versions began; In April 2016, sales of all-metal Gazelle Next vans started.

The substantial investments began to pay off: new cars are selling well on the domestic market: more than fifteen thousand buyers choose them every year. The Gazelle Next assembly production for the needs of the local market was also organized in Turkey.

Predecessor and main features of the YaMZ-534 engine

Externally, GAZelle Next has radically changed in comparison with the previous Gazelle. In the front part, attention is drawn to the large radiator grille and the large, voluminous bumper with fog lights integrated into it. The plastic body kit is made of four different segments. Due to this, in case of minor accidents, the metal front part of the car will not be damaged, and it will not have to be replaced.

The headlights are the same; almond-shaped, or teardrop-shaped. Only they are located much higher, at the junction of the plastic wings, the sloping hood and the side of the bumper. By the way, the long-standing problem of wing corrosion has been solved radically and forever: now they are not metal, but plastic.

The side rear view mirrors have increased by about a third. They became divided into 2 parts, one of them is panoramic. The mirror mounts have become much stronger and more reliable. In addition, the base already has electrically heated mirrors. The more expensive configuration also includes electrical adjustment. Under the cab on both sides there are hidden drawers for tools and the factory hood seal. Windshield washer nozzles are now located on the windshield wipers.

Raising the hood, one cannot help but notice that the engine compartment has become more spacious, thanks to which GAZ specialists were able to space out the intercooler and the main radiator of the cooling system. This, together with the fact that the purge area of ​​the radiator itself has almost doubled, significantly reduced the thermal load on the engine.

It is impossible not to note the abundance of foreign-made parts and components: ZF steering; front optics "Magneti Marelli"; anti-lock braking system manufactured by Bosch; "Mando" braking system; SKF gearbox bearings; Sachs clutch; wheel bearings "Schaeffler";

In motion, the “next Gazelle” has become quieter compared to the usual one, the smoothness of the ride on a broken road has noticeably increased, and the problem of suspension rigidity and noise in the car when driving in an unloaded state has been eliminated. Driving performance was improved by revising the aerodynamics and refining the cabin supports, improving the design of the rear suspension and springs (something that Gazelle owners have long pointed out).

The main innovation, which takes the Gazelle Next to a completely different level of comfort, is the new independent front suspension on double wishbones. Even the basic equipment is equipped with 9th generation four-channel ABS.

According to the manufacturer, another pressing problem of the Gazelles has been solved - the high susceptibility of the body to corrosion. It is claimed that the body of the Gazelle Next is of high quality. Only galvanized metal is used to make the running boards, hood, wheel arches, doors and side panels.

Especially for the production of the new family, an advanced hydroelastic stamping press “Quintus FlexForm” was launched in Nizhny Novgorod, which allows the use of a one-sided matrix when creating liquid pressure at a level of 100 MPa. Equipment is used to create body elements for Gazelle Next, making them of higher quality.

The YaMZ-534 Euro-4 engine is an in-line four-stroke diesel engine, with compression ignition, direct injection, liquid cooling, turbocharging and charge air cooling in an air-to-air heat exchanger. Each of the engine cylinders has four valves each.

Although the Yaroslavl Motor Company’s lineup already included the 4-cylinder YaMZ-204 engine, which was discontinued more than twenty years ago, this, as they say, was “a completely different story.” Because that engine was a heavy diesel engine. And the design did not even provide for its equipping with a turbocharging system. Therefore, the four-cylinder YaMZ-204 can be called the predecessor of the 534, but only with a stretch.

After all, the YaMZ-534 is a medium-sized in-line diesel engine, developed, as they say, “from scratch” by the design bureau of the Yaroslavl Motor Plant, together with the Austrian engineering bureau “AVLListGmbh”.

Distinctive features of YaMZ-534 are compliance with modern environmental standards Euro-4; the presence of an electronic control unit (ECU) and the use of a modern direct injection system using the CommonRail battery fuel system.

Achieving a high level of environmental standards was made possible largely thanks to the use of the EGR exhaust gas recirculation system. One of the advantages of this solution is simplification, and therefore reduction in cost, of placing the engine on the car.

“YaMZ-534” is a fundamentally new design, using the most current and advanced solutions, the rights to which belong to the GAZ Group (in recent years, this holding has included the Yaroslavl Motor Plant).

Lawn Next truck with YaMZ 53441-2 engine (150 hp)

For the serial production of diesel engines of the 530 family, a completely new plant was built and launched as part of YaMZ - Avtodizel OJSC. This new enterprise is located on the current outskirts of the city, as the locals say - “beyond the Volga”, about a twenty-minute drive from the old plant.

This is the most modern production of diesel engines not only in Russia, but throughout Eastern Europe.

This modern industrial site has almost a 90% level of production automation, and all production equipment on it is from the world's leading manufacturers. In addition to the new 530 series diesel engines, German engines for Mercedes Sprinter minibuses are also assembled here.

Among the suppliers of individual components and components of the new Yaroslavl 4-cylinder engine are such venerable manufacturing companies with a long-term and impeccable reputation as Bosch, ZF, FederalMogul, BorgWarner, MannHummel, Behr, Knorr/ Bremse" and others.

The casting of the block and cylinder head is carried out in Germany, at the FritzWinter enterprise.

However, the new Yaroslavl four-cylinder diesel engines do not consist entirely of imported components and components, as it might seem. For example, CommonRail fuel equipment is Russian-made, from the Yaroslavl Diesel Equipment Plant.

The electronic control unit and, what is especially characteristic, the software for it, were developed by St. Petersburg, and the production of the ECU itself was mastered at the Stary Oskol Automotive Electrical Equipment Plant.

The production of electronically controlled fuel injectors, providing increased spray pressure and multi-phase injection (three portions), has been established at the Altai Precision Products Plant in the city of Barnaul.

Currently, the price list of the Yaroslavl Motor Plant includes nine modifications of the YaMZ-534, in a power range from 136 to 190 horsepower. The YaMZ-534/CNG gas engine, which was the fruit of cooperation with a Canadian manufacturing company, stands out in particular.

Review of YaMZ-534 modifications and scope of their application

In terms of their capabilities, YaMZ-534 engines are very versatile. These motors effectively perform the functions of power units on a variety of equipment weighing up to 12 tons, together with cargo; or on road trains weighing up to 21 tons. It is allowed to use these engines on vehicles with a number of wheels from 4 to 6, with two or four driving wheels.

Initially, YaMZ-534 diesel engines, all their modifications and configurations, were intended for installation on MAZ, Ural (new model), GAZ and GAZonNext (gas fuel) trucks, as well as small and medium capacity buses of the PAZ brand.

The key differences between the individual modifications lie, first of all, in the settings of the ECU - an electronic fuel supply system optimized for specific tasks.

A more detailed overview of the specific application of modifications to these motors is as follows:

• “YAMZ-5340” is a basic modification used as a power unit for trucks, dump trucks, chassis, tractors with the wheel arrangement “4x2”, “4x4”, “6x2”, “6x4”, with a gross weight of up to 12 tons, road trains on their basis up to 21 tons - Minsk Automobile.

• YaMZ-534/CNG is the newest and most promising modification, launched into production only at the end of 2015. Powered by gas. At first, it will be equipped with new versions of GAZ trucks, and in the near future – with a wide range of all kinds of equipment for various purposes.

In addition, since May 2014, the plant launched serial production of an accelerated modification - "YAMZ-53472-10", with a power of 215 horsepower at 2600 rpm, specially designed for the new army armored vehicles "GAZ-233036" (it aka "SMP-2 "Tiger").

The main options for the Gazelle Next car are a truck, an onboard cargo platform; universal chassis for installing settings and all kinds of special equipment; bus in city and intercity interior design; all metal van. The vehicle is available with a standard or extended wheelbase.

1. The flatbed version differs from the regular Gazelle by a reinforced frame and the use of stainless materials. The architecture of the platform has also been improved. If previously only three euro pallets could be placed in the body, now their number has increased to five, which immediately increases transportation productivity by forty percent! The load capacity of the frame chassis, however, has not changed, but voluminous loads, according to tradition, prevail over particularly heavy ones. Yes, and periodic overload of the Gazelle Next, like the previous Gazelle, will not frighten you. Modifications of the onboard Gazelle Next:

Classification, designation and technical requirements." * GOST 17479.1-85 – Standard “Motor oils. Classification and designation." * API – American Petroleum Institute.

YaMZ-534 is an in-line four-cylinder diesel engine, which is a variation of the in-line 6-cylinder diesel engine YaMZ-530. The ICE model under consideration is installed on the mid-size LiAZ-42960 bus. In addition, this engine has proven itself well in the Pavlovsk PAZ-3205 and PAZ-3204 buses, as well as in buses of the newest Vector Next family. Diesel power reaches 150-170 hp. With. In 2016, YaMZ-534 received Euro 5 support. GAZ trucks and the LiAZ-529267 bus are equipped with the updated engine. The engine is equipped with a manual transmission and has a service life of 700-1000 km.

Technical characteristics of the YaMZ-534 engine

All of these modifications of the new four-cylinder diesel engines are maximally unified among themselves and cover the power range from 136 to 215 horsepower. At the same time, the minimum specific fuel consumption is, according to the manufacturer, 145 g/l.h.h. And this number is a very good indicator by modern standards, meeting the most current fuel efficiency standards.

Thanks to the presence of the innovative CommonRail direct injection battery fuel system, equipped with an ECU - an electronic control unit, precise fuel supply calibration parameters are achieved for a number of diverse operating modes. This makes it possible to simultaneously ensure both a reduction in fuel consumption and an increase in engine efficiency.

Some technical indicators in specific terms:

• Working volume – 4430 cubic centimeters;
• Power - from 136 to 215 hp, depending on modification, at 2300-2600 rpm;
• Number and arrangement of cylinders – 4, “L”;
• Cylinder diameter/piston stroke, in millimeters – 105/128;
• Compression ratio – 17.5;
• Maximum torque, Nm (kg/s.m) – 735 (75);
• Rotation speed at maximum torque – 1300-1600 rpm;
• The height of the crankshaft axis is 300 mm;
• Environmental indicators – Euro-4 (EGR POC);
• Overall dimensions (Length/Width/Height), in millimeters: 972/712/836;
• Engine weight, unfuelled: 480 kg;
• Cylinder operating order: 1 – 3 – 4 – 2;
• Power system: CR direct injection.

To achieve the Euro-4 environmental level, an EGR (exhaust gas recirculation) system and a catalytic converter with a replaceable filter are used.

We can hope that the new YaMZ-534 engine will become another example of a reliable, unpretentious and durable solution for a power unit. After all, the Yaroslavl Motor Plant has been the largest player in the industry for more than half a century and has not betrayed itself. In the sense that its classic products - engines of the YaMZ-236, YaMZ-238 family have an impeccable reputation as engines that are extremely durable and reliable, a sort of “perpetual motion machine” among diesel engines.

Engine "YaMZ 534" in the assembly shop of the plant

The new power unit, YaMZ-534, according to the manufacturer, has a predicted service life before major overhaul from 700 thousand to 1 million km; with the need for maintenance every 30 thousand km. (or 1000 hours of work).

The rate of oil consumption due to waste is no more than 0.1% of diesel fuel consumption, which corresponds to the most advanced examples of such equipment from the world's leading manufacturers.

The manufacturer's warranty for power units of this series is two years, or 100 thousand kilometers.

YaMZ-534 motors are in high demand on the market: their production volumes amount to tens of thousands of units per year. In this case, the first maintenance is scheduled after 15 thousand km (or 500 hours), the second and subsequent engine maintenance – after 30 thousand km (or 1000 hours)

Operating experience and reviews from YaMZ-534 owners

The owners of Gazelle Next note that this is truly a completely new, modern, comfortable and productive car. It is cheaper than imported analogues and is less expensive to maintain. The basic package is rich in options. Fuel consumption, although slightly higher than stated by the manufacturer, is generally pleasing.

It starts well in the cold, down to minus 20 degrees. In hot weather, you can often see regular Gazelles with the hood slightly open, with a plastic bottle inserted into the crack. On the Gazelle Next, the possibility of overheating was eliminated by installing a much larger aluminum radiator. The owners could not help but note the new cargo platform of the GAZelle Next.

One of the minuses is the archaic gear shift knob, which sticks out lonely from the floor in the middle of a modern and comfortable interior. “Where is the joystick on the podium{q},” spoiled consumers ask. People also grumble about the unassuming “oak” plastic of the panels, the shapes of which are cast in places of poor quality, with burrs. Problems often arise with wiring and rear lighting devices: the contacts either come off on their own or close for no apparent reason.

But in general, all owners of GAZelle Next, especially those who switched from regular Gazelle, unanimously declare that the cars of the Gorky Automobile Plant have actually made a sharp leap forward, and not only in design and comfort, but also in quality of performance and assemblies. The cost, although it cannot be called cheap, is still more attractive than similar “Europeans” - for quite reasonable money you can get a reliable, practical and comfortable car. Where it will be pleasant to work and earn money.

Experience of owners of cars with YaMZ-534 engines, produced in 2011-2013 and already, so to speak, “smelling gunpowder”, i.e. have proven themselves under conditions of intensive use, indicating that the motor is good. More specifically: reliable; when necessary - high-torque, when necessary - playful and resourceful; works quietly; and, what is especially important in our time, economical (about 15-17 liters).

Each buyer of diesel equipment of this type has two options: YaMZ-534 or Chinese-made Cummins.

The Yaroslavl motor, judging by experience and reviews, is much better: more unpretentious, trouble-free, and, although not particularly cheap; Still, in terms of the price of spare parts and the engine itself, it will be preferable. And “YaMZ-534” cannot boast of an inexpensive price quite naturally: after all, a considerable part of the components and assemblies on it are from European manufacturers.

However, “jingoism” in the field of new technical developments is inappropriate in our modern era. And using technologies and ready-made units from world industry leaders is, perhaps, the right decision. Since using them turns out, as they say, “a completely different song.”

Cabin "Gazelle Next"

The doorway area of ​​the Gazelle Next cabin is 23 percent larger than in a regular Gazelle. The interior has become taller and overall there is more space. The driver's seat "Isringhausen" is imported from Germany and provides lumbar support, as well as adjustment in all directions. It is possible to adjust the height of the seat belt fastening.

The plastic of the cabin panels is still inexpensive and rigid. However, it received a new shape and texture. The instrument panel includes 2 dials and an on-board computer display. The ergonomics of the interior are pleasing: there are many useful shelves and pockets, there are 2 cup holders and 2 bottle holders, there is a coat hook on the wall, and for an additional fee you can install a shelf for a radio station under the ceiling. Buttons and other control devices operate smoothly and look good.

An adjustable armrest has appeared between the seats, which does not interfere with changing gears at all. The left (door) armrest runs the entire width of the door; on the passenger door the armrest is noticeably shorter. By the way, GAZ specialists implemented this innovation “at the request of the workers,” who complained about the insufficient length of the cabin, which made it difficult to stretch out while lying at full height.

The Gazelle Next cabin is also distinguished by its safe design, due to the inclusion in the configuration of special power elements that have specified deformation points. In an accident, they take most of the impact. Seat belts received pretensioning devices.

In the double version, there is an additional swing door on the right side to facilitate the boarding and disembarking of passengers from the “gallery”. The basic package additionally includes a pre-heater, a heater, an increased power battery, a heated fine fuel filter and an additional 12V socket in the rear of the cabin.

GAZ YaMZ 534. Gives errors: P0366 - injector activation time exceeded P0283 - Abnormal reboot of the ECU P1709 Jammed emergency valve on the fuel accumulator. The opening of the emergency valve P3579 was detected - the fuel pre-filter is clogged - The fuel filter is clogged.

The client had previously changed the scythe to an internal combustion engine and fuel filters (all new). From another working machine I installed a pressure sensor on the rack and replaced the emergency valve on the rack. The replacement did not produce any results.

I wrote down the parameters while working, in the attachment. At some point, the actual pressure rises and errors begin to appear. And it works fine at idle.

Tell me which way to dig.

Check the power, especially the ground from the battery to the ECU (there is a separate wire)

Perhaps the emergency valve has failed (you can simply check it by hand, if the engine gets very hot when the engine is running, then it needs to be replaced), perhaps the return line is pinched or clogged, the pressure regulator may be jammed.

Have you checked the pressure control valve? there seems to be an error on it, and an emergency one is when the pressure in the rack is higher than its response pressure.

sorry Oleg_B no, he explains it very well.

There is a graph about nothing, a record of emergency mode.

I cleaned it and there was oxide on the contacts. The filter is new.

Now under load one error appears. (2865) P1121 Violation of the injection pump dispenser control mode - Maximum positive deviation exceeded
