Doosan air filter for the engine - a paper, felt or other air cleaner that prevents dust and dirt particles from entering the fuel / air mixture system. Just like the Doosan oil and fuel filter, the air contributes to a stable and trouble-free operation of the internal combustion engine. The purpose of the air filter For the smooth operation of the Doosan engine, as you know, you need air. If it contains mechanical impurities or dust particles, the functionality of the motor is impaired. The air filter serves as a reliable barrier to various kinds of contaminants. Replacing the Doosan air filter - a responsible process, to ignore which is unacceptable. Moreover, it needs to be done in a timely and regular manner. For Doosan heavy equipment, the filter change becomes especially urgent. The reason for this is the work of the Doosan heavy equipment in difficult conditions, such as quarries, mines, construction sites and so on, far from service organization. Therefore, the Doosan air →

The diesel Doosan injector is one of the main elements of the diesel engine power system. The Doosan injector provides direct fuel supply to the combustion chamber of the engine, as well as metering the supplied fuel at a high frequency (more than 2,000 pulses per minute).  Doosan Injector performs an effective spray of fuel in the space above the piston. Fuel as a result of such spraying takes the form of a torch. Doosan injectors of different fuel supply systems have design features and differ in the way they are controlled. The injectors are divided into two groups: mechanical; electromechanical; The principle of operation of the diesel power system with the mechanical control of the Doosan injector is as follows. A fuel from the fuel tank is supplied to the Doosan fuel pump of high pressure (CNT) (Doosan injection pump). The supply is provided by a Doosan feed pump, which creates a low pressure required to pump fuel through the fuel lines. Electromechanical diesel  →

Doosan injection pump is one of the main components of the diesel engine injection system. The Doosan pump, as a rule, performs two main functions: injecting a certain amount of fuel under pressure and regulation of the required timing of the injection. With the advent of battery injection systems, the injection timing control function is placed on electronically controlled Doosan injectors. The basis of the Doosan injection fuel pump is a plunger pair that combines a piston (plunger) and a cylinder (bushing) of a small size. Doosan plunger pair is made of high-quality steel with high precision. Between the plunger and the bushing, a minimum gap is provided - precision mating. Depending on the design, the following types of high-pressure Doosan fuel pumps (Doosan injection pump) are distinguished: in-line, distribution and main. In a series pump, injection of fuel into the cylinder is performed by a separate plunger pair. The distribution pump has one or more plungers, which ensu →

In direct injection engines as well as diesel engines, the Doosan electric fuel pump is used in the low pressure circuit for pre-supplying fuel to the high-pressure pump - Doosan injection pump. The electric Doosan fuel pump creates a fuel pressure in the limit of 0.3-0.4 MPa (in engines with direct injection - up to 0.7 MPa). The use of mechanical pumps in Doosan fuel injection systems is not possible due to low fuel delivery pressure. By design, the following types of electric fuel pumps are distinguished: roller, gear and centrifugal. In the Doosan roller pump, the fuel is sucked and injected by rotating the rotor and moving the rollers therein. As the space between the roller and the rotor increases, a vacuum is created, and the fuel fills this space. When the space is full, the fuel supply is cut off. As the rotor rotates, space decreases, the discharge port opens and the fuel leaves the pump under pressure. Similarly, the Doosan gear pump works where the fuel is sucked a →

Doosan fuel filters serve a vital function for modern vehicles that are sensitive to the quality of motor fuel. Unfiltered fuel may contain several types of contaminants, for example, pieces of paint and dirt that could get into the fuel tank during refueling, or rust caused by moisture in steel tanks. If these substances are not removed before the fuel enters the system, they will lead to rapid wear and damage to the Doosan fuel pump and Doosan injectors, due to the destructive effects of particles on important components used in modern injection systems. Doosan fuel filters also increase the engine's power, since the less pollutants present in the fuel, the more efficient the combustion. Some Doosan filters, especially on diesel engines, have the shape of a cup for collecting water at the bottom. The water can then be drained by opening the valve at the bottom of the bowl. A lot of Doosan fuel filters contain a water sensor connected to the engine control unit or directly to t →

The Doosan feed pump is a low-pressure fuel pump. The main objective of this device is the function of supplying fuel to a high-pressure fuel pump - the Doosan injection pump. Typically, a feed pump is installed on the injection pump housing or in the immediate vicinity of injection pump. Both pumps are connected by means of fuel pipes, through which fuel is supplied from one pump to another. The Doosan feed pump (low pressure fuel pump) is needed to pass fuel through the Doosan filters and then inject the fuel into the high-pressure fuel pump - the Doosan injection pump. It is worth noting that the feed pump pumps a little more fuel than the engine needs to operate. This swap "with a margin" allows you to maintain the optimum pressure in the fuel system, avoiding increasing loads.

The Doosan oil filter is a very important link in the Doosan lubrication system. During the operation of the engine, the oil flushes away the carbon deposits and engine wear products. The absence of a Doosan oil filter or its clogging will result in all these solid particles again falling between the parts of the engine, speeding up their wear and tear. Approaching thereby costly repairs. The replacement of the Doosan oil filter is made together with the replacement of oil. Design of Doosan oil filter 1 - oil inlets. 2 - outlet. 3 - the case of the oil filter. 4 - filter element. 5 - a spring. 6 - bypass valve. 7 - non-return valve. 8 - O-ring.

The Doosan oil pump is designed to create pressure in the lubrication system, and thus lubricate the moving parts of the internal combustion engine. The Doosan oil pump is driven by a Doosan crankshaft or Doosan camshaft by means of a drive shaft. By the nature of the control oil pumps are divided into uncontrolled and adjustable. Unregulated pumps maintain a constant pressure in the lubrication system by means of a pressure reducing valve. In controlled pumps, the constant pressure is maintained by changing the pump capacity. Depending on the design, oil pumps are distinguished for gear and rotary pumps. Doosan gear oil pump is a two-pinion gear - the driving and slave, housed in the body. Oil enters the pump through the suction channel, is captured by gears and injected into the system through the discharge channel. The output of the gear pump is proportional to the speed of the crankshaft. When the discharge oil pressure exceeds a certain value, the pressure relief valve op →
