Kamens diesel engines are renowned for their durability, economy, safety and efficiency. Cars with Cummins diesel engines receive positive reviews from motorists who install engines of this type instead of gasoline ones.
Confirmation of this can be found in printed publications on automotive topics and on the forums of specialized websites. Kamens engines develop significant traction force at low speeds, so they were noted by drivers who are not prone to frequent gear changes.
Many motorists especially emphasize how important it is to regularly and timely diagnose and service a diesel engine - then it will work flawlessly for many years.
Otherwise, the engine may, even due to seemingly insignificant reasons, fail or refuse to work even after a major overhaul.
Gasoline engine UMZ EvoTech 2.7
The Next Gazelle with the EvoTech 2.7 engine began production in 2014 and now most models can be purchased with this gasoline engine.
Leading designers of the GAZ Group and the South Korean giant Tenergy, a leader in the field of creating power units, took part in the development of the EvoTech 2.7 engine. The gasoline engine is designed for at least 400 thousand km, and it comes with a warranty of 3 years or 150 thousand km. The EvoTech engine compares favorably with earlier analogues produced at UMP. The new engine consumes 10% less fuel, torque has increased significantly, and traction and dynamic characteristics have improved. All these improvements are made without harming the environment and cost: EvoTech 2.7 meets the high requirements of Euro-4 and Euro-5 standards, and has the lowest cost of ownership among analogues. The improvement in traction and dynamic characteristics looks truly impressive, since it was possible to reduce the volume from 2.9 to 2.7 liters. The power characteristics did not deteriorate, since it was possible to reduce mechanical and thermal losses by changing the valve timing. The introduction of a new form of water jacket and modification of the cylinder head made it possible to increase the efficiency of the cooling system, while improving the thermal efficiency of the engine. The developers have improved the main components and parts of the engine. Among the innovations are a new design of pistons, cylinder block, camshaft and combustion chamber. The electrical equipment of the engine has changed significantly, as well as sealing connections, fastenings of a number of components, cooling systems, ignition, power and lubrication. All improvements are made within the framework of the traditional four-cylinder 8-valve design. The engine has become lighter and more technologically advanced; there are more plastic parts in its design. Due to this, the vibroacoustic characteristics have been improved. Products from reliable foreign manufacturers are used in the production of motors. The spark plugs, piston group, most hoses and sealing joints are supplied by Tenergy's neighbors on the Korean Peninsula - LG. Electronic sensors are imported from Germany and are produced by Bosch. Not without the Americans: Eaton Corporation supplies hydraulic compensators

Features of Gazelle engines
The main feature of the American engine on the Gazelle Next is its Chinese assembly. Engine spare parts are delivered to the Middle Kingdom, assembled and sent to Russian factories for installation in the car.
If you choose from an American engine and UMP EVO Tech, then it is better to install the latter on the Gazelle. Because Russian low-quality fuel, cold winters, and the careless attitude of car owners spoil engines.

Characteristics of the Cummins ISF engine
Engines for Gazelle from Cummins ISF2 require careful care. The engine is equipped with heated fuel filters. Has a turbocharger.
The engine consists of four cylinders and is located freely under the hood of a domestic minibus. Engine dimensions: 606x641x632 mm. The weight of the motor is 214 kg.
Attention! Thanks to such a small size, this engine is even suitable for Gazelle Business.
It is equipped with an electronic injection system and Common Rail electromagnetic injectors. Such a system helps reduce vibration and noise levels of the engine.
The combined lubrication system carefully lubricates all engine parts. The intake manifold is heated, and the engine is cooled with liquid cooling.
All the engine heat is directed to heating the intake air, so the ignition of the fuel-air mixture is excellent.
Characteristics of the YaMZ 53441 motor
After some time, domestically produced diesel engines began to be installed on Next. Gasoline engines became the pioneers in this matter.
This is YaMZ 53441. They are four-cylinder, four-stroke, in-line. Like the first ones, they are equipped with turbocharging. But the turbine is cooled through charge air. An air-to-air heat exchanger is installed.
Such engines belong to the Euro 4 eco-class. An EGR system and a catalyst are used to neutralize harmful gases. The fuel supply is carried out by a system installed by Bosch.
Additionally, the following can be installed on domestic engines:
- air conditioning compressor;
- power steering pump;
- compressor for air brakes.
The engine will be equally good at pulling these additional devices along with its main functions.
Upgraded Evotech engine
Over time, the diesel engine for the Gazelle Next was replaced by units presented by the Ulyanovsk Motor Plant. These are UMZ Evotech Turbo gasoline engines. First appeared on Gazelle Next since 2014.
The motor was created by the South Korean company Tenergy. Comes with a warranty of up to 3 years and 150,000 kilometers. This engine surpassed other engines with its power and economical fuel consumption.

The traction capacity of the Gazelle Next engine has been increased and the dynamics have improved. Ecological class not lower than Euro 5.
By adding valve timing, engineers managed to improve technical performance and reduce the volume of the Gazelle Next engine from 2.9 liters to 2.7 liters.
A new form of cooling system jacket was created. The efficiency of the motor as a whole has been increased. The main components of the engine, such as:
- camshafts. One of which is called sharp due to the shape of the cams. The first can increase engine power, but reduce torque, the second does exactly the opposite;
- the combustion chamber;
- cylinder block
have been finalized. There are many parts installed made of impact-resistant, heat-resistant plastic. Thanks to innovative technologies, it was possible to minimize the weight of the engine. Reduced oil consumption. To avoid detonation, a microprocessor ignition system is installed on the engine.
Attention! Hydraulic compensators are supplied by Eaton, an American company, and spark plugs and pistons are supplied by South Korea. The pistons are coated with a polymer layer containing molybdenum disulfide. This anti-friction coating ensures the longevity of the pistons.
Efficiency and safety of Cummins diesel engines
One of the main advantages of Cummins diesel engines is their efficiency. But even if you don’t take into account saving money, the opportunity to get rid of the motorist’s eternal worry about whether there will be enough gasoline before filling up is worth a lot!
Filling the tank with fuel before going on the road and not having to worry about running out of fuel along the way is a real pleasure. In addition, Cummins diesel engines are so durable that they work even when, according to all indicators, they should no longer work.
Although the efficiency of a diesel engine does not mean savings on car maintenance. The vast majority of drivers with experience in operating Cummins diesel engines are unanimous in the opinion that the principle “Pour out anything - even diesel from under a tractor, even sunflower oil” - will not lead to anything good.
The diesel engine will quickly fail and will not work even after numerous attempts to revive it. It is necessary to take at least minimal measures to maintain a Cummins diesel engine - then it will serve for a long time and without failure.
It is necessary to promptly fill in the correct type of oil, high-quality fuel (filtered or separated), promptly check and replace the pipes of the cooling system, nozzles, etc.
Owners of diesel cars are convinced that the safety of the Kamens diesel engine is much more important than its efficiency. Saving on fuel is good. But a burst fuel pipe and fuel pouring into the hot engine and wires can only cause regret that they were not replaced in time.
In such cases, you need to turn off the engine, wipe it with a cloth, replace the pipe - and you can drive on, since the possibility of a fire or explosion threatening life will be minimized.
