Increased Fuel Consumption Kamaz 740 Reasons • Throttle sensor

Severe wear of engine parts

In particular, there is a linear basic norm established for a value of 100 km, and there are standards that are determined for a truck engaged in transport transportation. In front of the radiator there is a plug for a hexagon, unscrew it, there is a screw with a lock nut, loosen the lock nut and add a screw, just don’t need much, about a quarter of a turn, then tighten the lock nut just so that the screw does not spin, you need to hold it somehow, it’s not very good convenient and the plug in place.

Specifications

The fuel consumption rate is an obligation of transport companies and other enterprises that have their own fleet of vehicles. But in relation to KamAZ dump trucks, this calculated parameter is of greatest importance, since the vehicle includes many modifications, each of which differs in individual fuel consumption.

Although there are generally accepted standards, they are not suitable for every specific situation. Calculation of standard indicators is carried out taking into account many factors, among which the following can be distinguished:

1. Estimated time of year the vehicle was used.
2. The technical condition of the vehicle and its service life.
3. Serviceability of the power unit - assessment of the condition of the filters is important here.
4. The quality of the fuel used.

Fuel consumption is influenced by a number of factors. Fuel consumption per 100 km depends not only on the car model, including modifications, technical characteristics, but also on its scope. In any case, the manufacturer determines the base value. But in real operating conditions, various nuances and other factors that accompany cargo transportation should not be discounted.

When calculating fuel consumption, the vehicle's carrying capacity is always taken into account. If it is equal to 7 tons, then when moving at a speed of 80 km/h, 30 liters of fuel will be spent for every 100 km traveled. Trucks with a load capacity of 30 tons will require 8 liters more.

Dimensions and load capacity

The operating systems and components of the truck were designed to withstand difficult operating conditions. Our review guest cannot be called an improved working version - this is a completely new model that was developed from scratch. From the very beginning, the car was equipped with a previous model cabin, which is already outdated. They decided not to touch it for now because the main efforts were directed towards researching the innovative chassis. A little later, the cabin was replaced with a more improved one. This made it possible to abandon the literally obsolete and morally old cabin. The new one began to look more beautiful, received new headlights (lens optics) and a visor. The car had a high roof, which had a lower belt and a unique buffer.

How to check the system for air leaks

There are two outlets on the KAMAZ fuel tank: fuel supply and return. So, you need to connect the air pumping hose from the receiver to the fuel supply and apply compressed air pressure to the low pressure fuel system, and turn off the return line. All connections, hoses, bolts with washers, they will show at the pressure where the air is leaking, fuel will flow from there. We eliminate all these shortcomings so that the system is airtight.

KamAZ’s diesel fuel consumption itself is quite high and therefore the cost of purchasing diesel fuel constitutes a very large expense item for any enterprise. For example, a very popular KamAZ model, the so-called collective farmer, KamAZ 55102, which can transport 7 tons of cargo at a speed of 80 kilometers per hour, consumes 31 liters. If you take another modification of KamAZ 55111, which has a load capacity of 30 tons, then its consumption is already 39 liters. Although the Neftekamsk plant, which produces these vehicles, is currently constantly concerned about reducing diesel fuel consumption, this figure is still quite high and therefore, in order to reduce or at least not increase consumption relative to the norms, the correct KamAZ driving technique is necessary.

To prevent fuel from going back into the tank

You can do one more trick; homemade people have already started to come up with this. We take the bypass valve from the injection pump pump, disassemble it, remove the spring and leave only the ball. We assemble the valve and install it on the coarse filter instead of a simple bolt. Now the fuel system is equipped with two valves and the fuel will not go into the tank. If one valve does not work, then the second one will hold. The ball simply falls to the bottom under the force of gravity and closes the flow of fuel. Everything is easy and simple, you can do the same for yourself.

Hello everyone, help me solve the problem I have a KAMAZ with a Bosch injection pump and an electronic pedal, turn off and start with a key. The problem is that it is very difficult to start for a long time. You have to turn it for 5-10 seconds, then it works smoothly. does not go away. and regardless of whether it is cold or just turned off! Has anyone encountered this? GOOD LUCK TO EVERYONE ON THE ROAD.

Average factors of importance - 10 nuances of high consumption.

A clogged air filter interferes with the correct operation of the incoming air flow sensors, as a result of which the electronic control unit calculates the required amount of gasoline or diesel for mixture formation with an error, which inevitably leads to increased fuel costs; If the temperature in the engine is higher than normal, the fuel that gets into the cylinder quickly evaporates, and the air contains less oxygen, so the combustion of the air-fuel mixture will not occur correctly.

A melted and clogged catalyst can significantly reduce engine efficiency and, as a result, provoke significant fuel consumption. through the plug it doesn’t help much, but try, you need a tubular Zhigovsky key 8-10 and a long simple screwdriver, I tried it, it didn’t help me, then a guy in the parking lot suggested that you remove the cover from the right in the front corner, you’ll see a carter, you need a key 22-24 and a second one for 10 with a large one, you’ll open it with a small one, you’ll support it and You unscrew the little thing itself a little, it shouldn’t be set more than the thickness of a razor blade, otherwise black smoke will pour out. When I did this, I ran the Ural hills more fun, and from Kemerovo to Mariinsk it was quick, but it didn’t work right away after several attempts, so try it.

The main reasons why the KAMAZ engine does not start: • KAMAZ had a problem with the engine speed not developing.

A story from the practice of repairing KamAZ 65115 photo 1

1. It often happens that the car is heavily overloaded, which leads not only to premature failure of various components, but also significantly increases the consumption of diesel fuel. Therefore, transport cargo weighing no more than that recommended in the instructions.
2. Before starting to drive, warm up the car engine and start driving smoothly without jerking. These jerks lead to slipping, and this in turn increases both fuel consumption and tire wear.
3. You can also use the route profile to save fuel. By increasing your speed slightly when going downhill, you will use less energy when going uphill.
4. For the trip, choose the optimal route, which will have a minimum number of traffic lights and traffic jams, since with frequent braking and subsequent acceleration, diesel fuel consumption will be the greatest.
5. Very often you can see a KamAZ truck decorated with a large number of lanterns, but each lighting device is extra grams of fuel consumed.
6. Well, the most important piece of advice is that only a serviceable car consumes a minimum amount of diesel fuel, and timely replacement of components and mechanisms can significantly reduce fuel consumption.

The fuel system has been radically changed, where a high-pressure fuel pump with a mechanical drive has been replaced by a Common rail electronic fuel injection system, supplied by the world leader in the production of auto electronics, Bosch. Check that there is no interference with the rotor at its extreme axial positions; if the rotor catches, replace the turbocharger Increased oil consumption Prolonged operation of the engine at idle speed Do not operate at idle speed unless necessary Oil leakage through the connections in the turbocharger lubrication system Tighten the connections, if necessary, replace the gaskets and rubber sealing rings The air filter or air intake cap is clogged. service the air filter or clean the hood mesh.

How to remove fuel injection pump from KAMAZ Euro 4

The technical characteristics of the engine and transmission, although they influence the car’s fuel consumption, not the least role is played by its quality. The recommended distance is 1 1.5 mm, but we will set exactly 2 mm, since in this case the fuel level will drop slightly, which will slightly lean the fuel mixture entering the engine in all modes except idle.

This is useful to know

As noted above, the 740 is a fairly common type of engine. The first internal combustion engine in the line was the 740 V8. Accordingly, the letter V means that the cylinders are arranged in two rows and the angle between them is less than 90 degrees. There are also L-shaped engines. The cylinders here are also placed in two rows, but at an angle close to 90 degrees. It is worth noting that the first KamAZ 740 engine (Euro-2) had a volume of 10,852 cubic centimeters. Moreover, its power was about 210 horsepower. Somewhat later, other modifications appeared with a power range from 180 to 360 hp. With.

Of course, the 740 was used not on gasoline, but on diesel fuel. The so-called “solar” among motorists had a whole host of advantages. The main aspect on the basis of which the type of fuel was selected was cost. Operating a large-volume internal combustion engine on diesel fuel made it possible to save money due to lower consumption. In addition, the life of the power unit was extended due to improved lubrication. For beginners, this type of internal combustion engine was extremely unusual, because there weren’t even spark plugs. The working mixture was ignited due to a high degree of compression. If on a VAZ-2107 gasoline engine the compression ratio is 8, then on the 740 it is 17 units.

KAMAZ-65806: three-axle tractor with increased payload capacity

In practice, 65806 is a further development of the three-axle 6x4 tractor of the new KAMAZ-65206 model range, but modified for more difficult operating conditions and transportation of more massive semi-trailers.

KAMAZ-65806 is equipped with the same powerful 12-liter, but economical and environmentally friendly Daimler OM457LA V/4 428 hp engine. with a torque of 2100 Nm. Excellent traction and dynamic properties are provided by the 16-speed manual transmission ZF16S 2220.

The modern level of driver comfort is guaranteed by the same, time-tested and European cargo carriers-based cabin based on the Mercedes-Benz Axor, adapted to Russian conditions.

However, for working with heavyweights, the KAMAZ-65806 tractor also has features that differ from the main Mercedes family:

• More powerful frame made of high-strength steel with 8 mm reinforcements in the side members.
• Use of double main gear and drive axles KAMAZ-6520 with wheel gearboxes for a load of 13 tons.
• Instead of air suspension, a rear spring balancer suspension is used.
• Instead of disc brakes, drum brakes with exchange rate stability control (ESP) and ASR system are used.

All this made it possible to prepare the tractor for hard work: for KAMAZ-65806, the permissible load on the SSU has been increased to 23.2 tons, and the total weight of the towed semi-trailer can reach 64 tons.

The service interval for KAMAZ-65806 is 60 thousand km, the total service life of the tractor is 800 thousand km.

The starter turns but does not start • Engine with a bosch ms 61 computer

The main reason for the malfunction of the fuel pump is wear of its parts, weakening of the tightness in the fits, increase in gaps in the moving joints, violation of the location of parts, deposits on the surface of parts in the form of dirt and carbon deposits. The reason that an engine with an injector has a high flow rate may be incorrect operation of the sensors with which the ECU analyzes the operation of the components.
