Engines "Cummins" (Cummins): specifications, reviews of specialists and photos

Car enthusiasts have heard a lot about the diesel engines of the American brand Cummins. Engines "Cummins" long and hard to install on trucks and cars of both domestic and foreign manufacturers. These motors are equipped with "Gazelle", "Kamaz", pickups Nisssan, various buses and other equipment. We will get acquainted with this producer and his products.

History of development of "Cummins"

For more than 95 years, the company has been manufacturing high-quality, economical and efficient Cummins engines. Today, this brand is considered one of the industry leaders.

Founded the company in 1919 in the United States, or rather, in Indiana. The founders can be considered Klessi Kammis, he was a first-class car mechanic. He was so inspired by the invention of Rudolf Diesel that in the same year he built his first unit. He had only 6 liters. from. Power, but it was just the beginning.

Engine for farmers

The motor soon became widespread and popular with local farmers. At the end of the season, the engine could be returned at half price. In 1929, Cummins began manufacturing diesel engines for yachts and ships, and then diesel generators went into production. In the 1930s, Cummins diesel engines began to be installed on most trucks and Packard limousines.

Today the manufacturer supplies diesel units with a capacity from 70 to 3500 liters. from. Motors are developed at 56 different enterprises, which are located around the world. More than 160 countries use the company's products in various fields of industry and production.

Main characteristics

Since the company's product line is large, their capacity varies widely from 70 to 3500 liters. from. The peculiarity of these motors is that the manufacturer specializes only in diesel engines. Due to the narrow focus, it is possible to achieve very high results. For example, the torque on some models is 13,000 Nm.

Among the engines you can find models with the most different performance. Among the most popular - 4-cylinder and 6-cylinder in-line units. However, the rulers also include V-shaped models.

The timing on these motors in the majority consists of the mechanism of the valves, the camshaft and the drive. The valve mechanism is represented in the form of the valve itself and the seat itself. To increase gas exchange rates, as well as increase in power, each cylinder of engines of this brand contains 2 inlet valve pairs and exhaust valves. Depending on the model, the camshaft can be located either below or above.

The power system is based on electronic injection. This allows the engines to be economical enough. The fuel system uses patented filters manufactured using the highest technologies, and the pipelines are made of corrosion-resistant materials that have minimal hydraulic resistance. This allows the company to be the industry leader.

Cummins ISF Family

At the moment, the family of diesel motors ISF is represented by two four-cylinder diesel engines of 2.8 liters and 3.8 liters capacity. The first goes to "Gazelle", the second is set to "Vladai". Such a difference in the volume of motors is achieved due to different sizes. At the same time, the design of both units is maximally unified. Engineers use common parts in both power units by 70%.

The 2.8-liter engine has 6 power settings. In "Gazelle" use is almost the most minimal of them. This setting is 120 liters. from. In addition to this light version, there are still models with 131 liters. S and 150 liters. from. As for the torque, it is about 360 Nm at 1800 rpm. If you give the crankshaft to untwist high speed and adjust the feed, then you can get three more power settings.

The engine "Cummins Valdai"

The 3.8-liter engine allows Valdai to have quite good demand in the market. Today, this car can be safely compared with some foreign cars. This unit has only three power settings. The truck is equipped with a setting of 154 liters. from. Not the most powerful, but quite sufficient for such a machine.

If you are familiar with the line of diesels of this manufacturer, then the 3.8-liter engine in its design features something like a liter engine. The unit is equipped with a cast-iron block of cylinders without sleeves. Here, the same for each cylinder head of the same cast iron, traditional four valves, turbocharger. The machine is also equipped with a common rail fuel system.

Fuel consumption

Those of the drivers who used Valdai with the Minsk engine confidently declare that Cummins is more economical. On average, the flow is about 14-17 l / 100 km.

The engine on "GAZelle Cummins"

On the "Gazelle" set the Chinese "Cummins". Let's get to know him better. This is a power unit of 120 liters. from. With a torque of 297 Nm.

The engine characteristics are more than good for domestic drivers. Almost the same indicators were once a gasoline engine with GAZ-53. But the carrying capacity was not 1.5 tons, but the whole 4.

Austrian motors, which were equipped with cars before, significantly lose "Cummins". Even powerful ZMZ-405 lose to diesel by torque. This is the basis of everything, hence the best dynamics in overclocking, easier touching the loaded car.

The location of the motor in the "Gazelle"

The engine "Cummins" 2.8 was successfully placed under the hood of the car. According to its geometric characteristics, it can be compared with ZMZ-402. The unit was designed as a universal motor, not tied to any model. It turned out to be quite compact and convenient.

Above is a vacuum pump. The water pump is located on the side of the cylinder block. In addition, the pump is combined in a single unit with an oil pump. The oil pump is almost the same as the VAZ-2108. This pump, given its size, has excellent characteristics. The drive for the water pump is a poly-V-belt, which also serves as a drive for the fan.

Features

The engine on the "GAZelle Cummins" differs from the distributor shaft in the block, as well as the timing drive in the form of a single-row chain. In this case, the chain itself is located on the flywheel side. Engineers did this in order to eliminate unnecessary noise. The chain is equipped with an automatic tensioner. You can forget about their maintenance, they are so reliable. GBC gaskets - type-setting, from steel sheets, so they do not require special service.

There is an interesting feature. It is interesting that the drive of the fuel pump is activated not by means of a chain, but by a separate gear on the crankshaft. So, engineers have optimized the "Cummins" engine. The device is designed in such a way as to exclude unnecessary work for the circuit.

For the engine to operate in our latitudes, it is equipped with a heater for easier start-up. An electric spiral can be found in the intake manifold. Fuel filters are also equipped with heating.

Maintenance and repair

Manufacturers recommend regular maintenance of main components, change lubricating fluids, check the operation of the electronic part, regularly replace fuel filters. It is recommended to carry out engine adjustments according to the passport. Then it will not fail and will not have to be repaired. According to the passport, the frequency of service is quite large. This pleases carriers.

If the engine fails, before performing the repair of Cummins engines, it is advisable to conduct electronic diagnostics. This unit is equipped with an electronic system, which by error codes will make it clear which particular node has failed.

Owner feedback

Owners of Valdai with ISF 3.8 believe that the car turned out to be very practical. In addition to the economy of the diesel unit, the operating costs are also very low. This is all combined with a high resource unit nodes.

But that's not all, what pleased the car owners engine "Cummins." Reviews say that this is a virtually problem-free unit. With timely service and at all trouble-free. The machine starts up even at the lowest and most extreme temperatures. Fuel consumption within 11 liters. Of course, fine adjustments do happen, but serious breakages are not observed.

Engine drivers are satisfied. Many are transplanted to GAZel from foreign cars. For the motor that is produced in China, this is the top of the possibilities. In repair it is quite simple, if you understand the device of diesel engines, then most standard breakages can be treated independently without visiting official service centers. Too often not to repair the engine "Cummins", motorists' opinions are advised to make regular replacement of oil and consumables.

Many drivers complain about the high level of noise from this diesel engine, especially if they used to go on gasoline units. Yes, the noise is still noticeable from it, all the more under the hood the turbine is also located. Many complain that in the summer the car gets very hot. Some people write that there is not enough dynamics. The unit is not suitable for those who like high speed. The car is actively accelerating at 2000 rpm. With a turbine.

The cost of motors

Those who decided to buy the engine "Cummins" - the price is about 500 000 p. For this cost, you can buy a 2.8 liter engine for "GAZelle". "Cummins Valdai" will cost 625 thousand rubles. Of course, this is very expensive. But there is another way. For 150 thousand rubles you can buy an ideally working power unit with a mileage on the "GAZelle". This is an excellent price for a Chinese engine. What is most interesting, its resource is very large, about 500 thousand kilometers. For such a price this is a very good option. Yes, and fuel consumption is less than that of analogues such as UMP and ZMZ.

So, we found out what the Cummins engines have, car owners' reviews, cost and specifications.
