Diesel engine fuel system operation

The fuel system of the diesel engine ensures the supply of gasoline to the cylinders. It is the main component of the diesel car design. Consider the principle of its operation and common malfunctions.

The circuit consists of high and low pressure sections. A section with low pressure prepares and transfers fuel to the system with high pressure. Which is necessary to finally transfer the fuel into the combustion chamber of the engine. The low-pressure section consists of cisterns, pumps, separator, filter, heater and fuel drive.

Fuel passes through all the parts, before it hits the highest stage of the diesel. The next stage is a smaller series of details. The most important element of the high pressure section is the fuel pump, which consists of injectors, and the pump itself is connected to the fuel line.

There are several reasons that lead to malfunctions in the fuel system. One of them is not high-quality diesel fuel, it is becoming increasingly difficult to buy qualitatively. But the most basic of them is the wear and tear of certain knots. The first thing to consider is the axis of the regulator lever, worn out faster than others. After a while, the elasticity that the rubber sealing ring, located at the low pressure stage, can decrease. In the course of active use of the vehicle, various foreign accumulations take place, so you should periodically clean up the carbon deposits and dirt so that the system parts can work for a long time and reliably.
The main causes that lead to problems with the engine system are the misuse or unskilled motor maintenance. Regardless of the car, all drivers must perform its maintenance every 7,5 thousand km. Maintenance includes the replacement of oil, checking the operability of parts and some other actions. Due to the washing of the diesel fuel system, various malfunctions can be eliminated.

One of the most common problems, negatively affecting the diesel fuel system, is the burnout of the piston. To prevent this problem, flushing the fuel equipment every two years.

If your system becomes faulty, perform some actions to correct this situation. First, pump the fuel system. If there have not been any changes, consider this problem in more detail. Check how all the contacting elements, wires, terminals, injectors work.

If the problem is serious enough, it's best to contact the car service center. The driver, without experience in working with the engine of the machine, is unlikely to be able to liquidate this malfunction on his own. In addition, if you were unable to find out the exact cause of the malfunction, you need to conduct a professional diagnosis of the fuel system in one of the car-care centers.
