Motorists have already heard a lot about the diesel engines of the American brand Cummins. Cummins engines have long been stubbornly installed on trucks and cars of both domestic and foreign manufacturers. These engines are equipped with Gazelles, Kamaz trucks, Nisssan pickups, various buses and other equipment. Let's get to know this manufacturer and its products better.

Cummins Development History

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

The company was founded in 1919 in the United States, more specifically, in Indiana. The founders can be considered Clessi Cummis, he was a first-class auto mechanic. He was so inspired by the invention of Rudolf Diesel that in the same year he built his ownfirst unit. He had only 6 liters. With. power, but that was just the beginning.

Engine for farmers

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

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

Key Features

Since the company's product line is large, their power varies widely from 70 to 3500 hp. With. The peculiarity of these engines 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 reaches 13,000 Nm.

Among the engines you can find models with a variety of designs. Among the most popular are 4-cylinder and 6-cylinder in-line units. However, the range also includes V-shaped models.

The timing on these engines mostly consists of a valve mechanism, a camshaft and a drive. The valve mechanism is presented in the form of the valve itselfand saddles. To increase gas exchange rates, as well as increase power, each cylinder of engines of this brand contains 2 inlet and exhaust valve pairs. Depending on the model, the camshaft can be located both below and above.

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

Cummins ISF Family

At the moment, the ISF family of diesel engines is represented by two four-cylinder diesel engines with a volume of 2.8 liters and 3.8 liters. The first goes to the Gazelle, the second is installed on the Vladai. This 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 nodes at 70%.

2, 8-liter engine has 6 power settings. The Gazelles use almost the most minimal of them. This is a 120 hp setting. With. In addition to such a lightweight version, there are also models with 131 hp. s and 150 l. With. As for the torque, it is about 360 Nm at 1800 rpm. If you let the crankshaft spin up to high speed and adjust the feed, you can get three more power settings.

Cummins Valdai engine

3, 8-liter engine allows"Valday" 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. With. Not the most powerful, but quite sufficient for such a machine.

If you are familiar with the range of diesel engines from this manufacturer, then the 3.8-liter engine is somewhat similar to liter engines in its design features. The unit is equipped with a cast-iron cylinder block without liners. Here, a common head for each cylinder is made of the same cast iron, traditional four valves, a turbocharger. Also, the machine is equipped with a common rail fuel system.

Fuel consumption

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

Engine for GAZelle Cummins

The Chinese Cummins were installed on the Gazelle. Let's get to know him better. This is a 120 hp power unit. With. with a torque of 297 Nm.

Engine performance is more than good for domestic drivers. Almost the same indicators were once in a gasoline engine with a GAZ-53. But the carrying capacity was not 1.5 tons, but as much as 4.

Austrian engines, which were equipped with cars before, significantly lose to Cummins. Even powerful ZMZ-405 lose to diesel in terms of torque. This is the basis of everything, hence the best dynamics during acceleration, easier starting of the loadedvehicle.

Location of the motor in the "Gazelle"

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

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

Features

The engine on the GAZelle Cummins is distinguished by a camshaft in the block, as well as a 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. Cylinder head gaskets are type-setting, made of steel sheets, so they do not require special service.

There is an interesting feature. Interestingly, the fuel pump drive is not driven by a chain, but by a separate gear on the crankshaft. So, the engineers optimized the Cummins engine. Its device is thought out in such a way as to exclude unnecessary work for the chain.

Tothe engine could work in our latitudes, it is equipped with heating for easier starting. An electrical coil can be found in the intake manifold. Fuel filters are also heated.

Maintenance and repair

Manufacturers recommend regularly servicing the main components, changing lubricants, checking the operation of the electronic part, and regularly replacing 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 an engine fails, it is advisable to carry out electronic diagnostics before repairing Cummins engines. This unit is equipped with an electronic system that, by error codes, will make it clear which node is out of order.

Owner Reviews

Valdaev owners with ISF 3.8 think the car turned out to be very practical. In addition to the efficiency of the diesel unit, the operating costs are also very low. All this is combined with a high resource of the units of the unit.

But that's not all that pleased car owners with the Cummins engine. Reviews say that this is an almost trouble-free unit. With timely service and completely trouble-free. The car starts even at the lowest and extreme temperatures. Fuel consumption within 11 liters. Of course, minor adjustments happen, but serious damage is not observed.

Drivers are happy with the engine. Many change to GAZelles from foreign cars. For a motor that is made in China, this is the top of the possibilities. It is quite simple to repair, if you understand the design of diesel engines, then most standard breakdowns can be treated on your own without visiting official service centers. In order not to repair the Cummins engine too often, motorist reviews advise regular oil and consumable changes.

Many drivers complain about the high noise level from this diesel engine, especially if they used to drive gasoline units. Yes, the noise is still noticeable from it, especially since the turbine is also located under the hood. Many complain that the car gets very hot in the summer. Someone writes that there is a little lack of dynamics. The unit is not suitable for those who love high speed. The car is actively accelerating at 2000 rpm. with turbine.

Cost of motors

Those who decide to purchase a Cummins engine - the price is approximately 500,000 rubles. For this cost, you can purchase a 2.8 liter engine for a GAZelle. "Cummins Valdai" will cost those who wish 625 thousand rubles. Of course, it is very expensive. But there is another way. For 150 thousand rubles, you can buy a perfectly working power unit with mileage for a GAZelle. This is a great price for a Chinese engine. What is most interesting, its resource is very large, about 500 thousand kilometers. For the price, this is a pretty good option. Yes, and fuel consumption is less than that of analogues of the UMP typeand ZMZ.
