The realities of our time force domestic entrepreneurs involved in cargo transportation to take all possible measures to reduce vehicle maintenance costs. Significant savings are achieved by using diesel fuel instead of gasoline, which is becoming more expensive every day.
Therefore, most businessmen in the transport sector prefer cars with engines running on this available fuel. One of these power units is the Cummins 2.8, the technical features of which are brought to your attention. The main advantages of this diesel engine will also be discussed here and the design characteristics will be briefly outlined.
Cummins 2.8 power unit, performance qualities and main advantages of the engine
It is known that cars used for commercial purposes must have sufficiently high performance coupled with acceptable operating costs. It depends on the engine equipping the vehicle. The Cummins ISF 2.8 engine fully meets the requirements.
The traditional reliability of the power units of this corporation is complemented by environmental safety, manifested by reduced noise levels and harmful emissions.
Separately, it should be noted that the small dimensions do not prevent the motor from providing sufficient power along with a completely acceptable torque.
Increased performance allows the engine to be installed in vans and light trucks intended for commercial use.

Fuel system of the Gazelle Cummins ISF 2.8 engine
The Cummins ISF 2.8 diesel engine of the Gazelle Business uses a fuel system with a common high-pressure fuel line and an electronic control system. The high pressure fuel line system consists of 4 main elements: the gear fuel pump, the high pressure pump, the common high pressure fuel line and the injectors. The high pressure pump supplies fuel to the common high pressure fuel line regardless of engine speed. Fuel under high pressure accumulates in this fuel line, from where it is constantly supplied to the injectors. The ECM regulates fuel supply and injection timing by turning on the injectors. A water separating fuel filter must be installed on the fuel intake side. It is located outside the engine and contains a manual booster pump.
Fig.6. Cummins ISF 2.8 diesel fuel system diagram 1 - Fuel supply from the tank, 2 - Fuel filter, 3 - Fuel water separator drain pipe, 4 - Booster pump, 5 - Fuel supply to the fuel pump, 6 - High pressure fuel pump, 7 - Fuel supply into the common high pressure fuel line, 8 - Common high pressure fuel line, 9 - Fuel supply to the injectors, 10 - Injector, 11 - Drain fuel from the injectors, 12 - High pressure reducing valve, 13 - Drain pipe of the high pressure reducing valve, 14 - Drain fuel line, 15 - Draining fuel into the tank The gear fuel pump of the Cummins ISF 2.8 diesel engine of the Gazelle Business car creates a pressure of about 303 - 1303 kPa, due to which the fuel is cleaned in a filter installed on or outside the engine before entering the injection pump. In this pump, the fuel pressure increases to a level of 250 - 1600 bar in three radial discharge chambers. The electronic fuel control system actuator valve, installed at the inlet to these chambers, regulates the amount of fuel entering them. To do this, it uses signals from the ECM, which maintains the pressure in the common high-pressure fuel line at the required level. Fuel that does not enter the plenums exits through the cascade bypass valve. It directs part of the fuel under pressure into the lubrication system channels of the Cummins ISF 2.8 diesel high-pressure pump and then drains the fuel into a tank, which accumulates fuel and distributes it between the fuel lines of individual injectors. It contains a sensor that monitors the pressure created in it by the high-pressure pump. The signal from this sensor is used by the ECM to control the flow of the high pressure fuel pump. In addition, there is a pressure reducing valve in the common fuel line. It works as a safety valve, releasing excess pressure if the pressure in the fuel line exceeds a set level. Fuel drained from the common high pressure fuel line is returned to the fuel tank through the fuel return line.

Catalogs of spare parts and assembly parts
Power unit design
First, let's look at a brief description of the internal structure of the Cummins 2.8 series engines. Thorough knowledge of such information allows you to independently perform simple engine repairs, without turning to the professional help of mechanics in specialized workshops.
Increased strength of the cylinder block is ensured by the material used. In Cummins power units of the ISF line, it is represented by gray cast iron. Distinctive features of the engine include maintainability and the ability to replace cylinder liners.
The valves are made of heat-resistant steel and are additionally equipped with special chrome-plated curtains to protect against scuffing. To improve the functionality of the valve system, special reinforced springs are designed. The similar design of all valves does not at all indicate their interchangeability. Correct installation is facilitated by special engraving on each part.
Due to the peculiarities of the manufacturing material, the aluminum block head is characterized by increased resistance to corrosion. They also influenced the weight reduction of the power unit.
The tension of the single-row chain in the timing drive of the same name is carried out by an automatic device. By the way, the chain, like the tensioners in the engine in question, are maintenance-free parts.
The four-cylinder, 16-valve diesel power plant performs useful work in four strokes. Fuel is supplied to the unit under the control of an electronic system. The common crankshaft is driven by pistons located inside the cylinders, which are arranged in a row in the engine compartment. The camshaft has an overhead position.
In the cooling system, liquid is forced to circulate in a closed circuit. The oil supply is carried out in a combined way: in parallel with the high pressure, lubricant is sprayed.
Overhaul of cummins engines (cummins) 2.8
A planned overhaul of the Cummins 2.8 engine is carried out after 500 thousand km, but sometimes a breakdown can happen earlier.
To carry out the work, the power plant is removed from the engine compartment and disassembled on a stand. After disassembly, the master assesses the condition of the parts and carries out troubleshooting. The cylinder block itself is bored and lined. The block head is completely sorted out and faults are rejected. The overhaul includes washing of components and parts.
The finished engine is assembled, first a cold run-in is carried out, and then a hot run-in. Sometimes assembled spare parts, such as a crankshaft, piston group or cylinder block, must be replaced. By the way, about 70% of spare parts for engines of the 2.8 and 3.8 series are identical.
Overhauling an engine is one of the most difficult service jobs, so the smart decision would be to entrust it to the specialists of AgregatAvto. Extensive experience in such work and professional equipment will allow service technicians to carry out repairs quickly and provide a guarantee on the work for 185 days.
Engine operational features
In the capable hands of a caring owner, the S4129P power unit, with proper maintenance, will last much longer without unexpected failures. Do not panic when an error code 1117 is detected in the system.
Thoroughly studied technical characteristics will help even an inexperienced driver master the manual for self-repair of the Cummins ISF 2.8 series engine:
- in a four-cylinder engine, the mixture is supplied through an intake device represented by two valves, and a similar number of exhaust elements are intended for output;
- engine capacity is characterized by a value of 2.781 liters;
- the cross section of each cylinder is 94 mm;
- The piston moves progressively up and down at a distance of 100 mm. This value is called the working stroke;
- when the crankshaft rotation speed reaches 3200 rpm, the power unit develops power of 120 hp;
- According to manufacturers' statements, confirmed by time, the engine resource exceeds 500 thousand km. Of course, it is possible to achieve such an indicator if due attention is paid to the timely maintenance of all installation mechanisms;
- The environmental safety of the engine is confirmed by compliance with Euro-3 and Euro-4 standards.
Separately, it should be noted the reduced fuel consumption, amounting to 8.5 liters of diesel fuel in city mode and 10.2 liters when driving on the highway.
Coupled with the low price of diesel fuel, this figure is considered very acceptable for commercial vehicles.

Video presentation of the Cummins diesel engine line:
Advantages of the power unit
The competitiveness of Cummins 2.8 is maintained at a decent level. The popularity of diesel engines in this series is explained by the following advantages:
- Manufacturers have improved the design of the motor and improved the design;
- the use of composite materials for the manufacture of the valve cover, pan and some other elements helps reduce noise and vibration levels during operation of the unit;
- easier access to the main components and mechanisms, made possible thanks to the modular structure of the engine, simplifies the repair process;
- the use of a catalytic exhaust gas converter helps the unit comply with Euro 4 standards.
From the above it follows that the Cummins 2.8 diesel engine is able to compete with gasoline engines from well-known manufacturers. For small business owners, this solution is optimal.
price and quality, gasoline or diesel, about spare parts, disputes, maintenance
The new Gazelle brand with a Cummins diesel engine was presented in 2010, and in 2011 reviews from owners appeared. In three or four years, the car took its rightful place on the Russian market. It is interesting to compare the first impressions of the new model and later ones, reflecting the experience of long-term use.
The engine installed on the new Gazelle was developed by the world famous American company Cummins. Its power is 120 hp, the mileage between major repairs is 500 thousand km, the assembly is Chinese. It is the behavior of this engine that is most often discussed on forums today.
Advantages of a Gazelle car with a Cummins diesel engine
The first reviews of the Gazelle with the Kamens diesel engine were very critical. Professionals and car enthusiasts noted, first of all, the increase in price of the model compared to the previous version.
The Gazelle-Kamens minibus has earned disapproval due to its insufficiently comfortable interior and poor sound insulation. Many motorists reacted negatively to the replacement of the domestic 406 engine with the American Kamens.
Radical car experts said that the Gazelle was in demand due to its low price, availability of spare parts and a good 406 engine, that is, because of what the new model lacks. From this they concluded that there would be no demand for a new modification of the car.
However, the pessimistic forecasts did not come true. The new diesel Gazelle travels along the roads of Russia in the guise of trucks, minibuses, vans, mobile workshops, etc.
The comfort of the interior of minibuses has ceased to be a subject of discussion, the topic has quickly exhausted itself, and, in essence, this parameter is at a completely acceptable level.
However, the operation of the engine receives endless discussions and comments.
Gasoline or diesel "Gazelle"
The dispute about which engine was better was resolved during operation. For the area of use of the Gazelle, diesel is preferable. This was shown by sales dynamics: 80% of Gazelles in use are equipped with a Cummins diesel engine, reviews of which have become positive and friendly.
Most owners of diesel cars note the endurance of the engine and its good service life. A mileage of 500 thousand km between repairs is not a theory, but a reality. For gasoline engines, such a mileage without repair is rather an exception. Diesel Gazelles are cheaper to operate.
At first, the Chinese assembly was an unimportant recommendation for the engine. Products from China are the living embodiment of the slogan “cheap and cheerful.” But experienced motorists argued that this does not apply to the Cummins engine, made using approved technology, in compliance with all quality standards, tested at various stages of production.
An engine made by Chinese workers at an American factory is no worse than an American one, even more American than in America, experts joked
Should I add oil to fuel with a Cummins diesel?
And yet problems arise during operation, especially in winter. A popular topic for discussion on forums is the problem of clean fuel. Drivers note with annoyance the presence of water in diesel fuel. Such an impurity disrupts the operation of the engine. The origin of water in diesel fuel is moisture condensation in the fuel tank.
Some drivers try to improve engine performance by adding oil to the fuel. Is such a measure justified? Experts say: this should not be done. Once upon a time, when using two-stroke internal combustion engines, this made sense, but for modern engines, the oil in the engine is just carbon deposits and soot.
It is proposed to improve engine performance in another way - warm up the fuel filters, fuel intakes, drain the sediment from the filter, add special additives to the fuel that eliminate water from the fuel tank
Spare parts and fuel for the Gazelle car with Cummins diesel engine
An inexhaustible topic for discussion is original and fake spare parts. The problem is, motorists note, that they are often impossible to distinguish from each other.
Fuel filters must be original to protect the injectors, experienced people say. They are objected to: original filters do not save you from troubles. This means it’s a fake, say enthusiasts of the original filters.
In essence, the same can be said about other spare parts, but it is filters that are most often suspected of being unoriginal, due to annoying injector failures associated with expensive repairs.
Most drivers tend to attribute problems that arise to low-quality fuels and lubricants. Buy fuel only from reliable dealers, car owners urge each other.
But this is not a panacea, others note. It is enough to buy fuel at a gas station of a different company than always, and the engine knocks, the injectors become clogged, and other troubles occur.
The problem of the quality of fuel and lubricants really exists, but most of the troubles attributed to fuel occur in the cold season - this is the opinion of experienced people. Diesel fuel thickens in the cold.
Cummins diesel engines are very demanding on fuel quality. Despite the simplicity of Cummins fuel systems, they require some maintenance. But not every driver will be able to do this on their own.A competent approach to the maintenance and repair of the Cummins 2.8 engine can provide all the conditions so that it can reveal all the capabilities that the designers have built into it. Read about engine repair in this article.
Different batches of fuel react differently to lower temperatures. Winter diesel fuel is produced for use in winter. If the temperature is below -35°C, then arctic fuel is needed.
The problem is that at normal temperatures, neither the color nor the smell of winter and summer fuel differ. If the temperature fluctuates significantly during the day, the wrong type of fuel can do a bad job: at a certain point, the fuel will turn into a jelly-like mass.
Timely transition from summer to winter diesel fuel and vice versa is an important condition for flawless engine operation. In addition, the fuel system must be warmed up while parked.
Craftsmen advise: if there is no diesel fuel in the winter, add 10% kerosene to the summer one. However, not everyone agrees with the benefits of this measure.
Injectors and batteries for Gazelle with Cummins diesel
“I bought a diesel Gazelle - save money for injectors,” the owners of diesel cars from the Gorky Automobile Plant note with annoyance. Indeed, malfunction of the injectors is one of the main reasons for contacting a car service center.
However, this problem does not happen with all engines. Many car owners note the long-term trouble-free operation of injectors, as well as all car systems in general.
The battery for a diesel engine must provide high starting current. This is especially important in winter. Viscous diesel fuel will not ignite with enough current to start a gasoline engine.
The oil capacity of a Kamens engine depends on the type of engine, the number of cylinders and the type of oil pan. An insufficient amount of oil leads to a decrease in pressure and deterioration of the lubrication system, which entails accelerated wear of engine mechanisms.
In this article we will try to figure out how the GAZ Valdai model was transformed after these cars with the CUMMINS ISF3.8 diesel engine began to be produced, and what is the fuel consumption of the Valdai with a Cummins engine.
Therefore, to operate a diesel Gazelle in winter, new batteries are needed; it is recommended to change them no later than after three years. In case of winter problems with the engine, they are sometimes eliminated by replacing the battery.
The electrolyte level must be high. Commentators on the forums note: a battery removed from a diesel Gazelle due to its unusability can work well in a car with a gasoline engine.
Cummins winter maintenance
Many problems can be avoided if, on the eve of cold weather, you give the Gazelle into the hands of car service specialists. The list of measures to prepare a car for winter is extensive, and the car owner does not always know all the intricacies of this procedure. If he knows, he can cope with the preparations for winter on his own.
It is necessary to drain the sediment from the filter and tank, check the electrolyte level in the battery, clean the terminals so as not to overheat under high current loads, check the glow plugs...
However, recommendations on forums may have an advisory voice. To properly operate the vehicle, you must carefully read the accompanying documentation.
Compliance with operating rules, regular preventive maintenance, good preparation of the car for the winter season - these measures can extend the service life of the car for years, as all motorist experts believe.
Recently, when drivers have become more familiar with the new Gazelles, most of them agree that a Gazelle with a Cummins diesel engine is a great boon. This is exactly what the reviews that are available in large numbers on various Internet forums indicate.
