What are the special maintenance requirements for electronic fuel injection diesel engines?

Compared to traditional diesel engines, electronic fuel injection diesel engines have some special maintenance requirements, mainly due to their highly electronic control system and precise fuel injection technology. The following is a detailed explanation of the special maintenance requirements for electronic fuel injection diesel engines:

High fuel quality requirements:

Electronic fuel injection diesel engines have strict requirements for the quality of diesel, as impurities and moisture in the fuel can easily block the injection holes and affect the atomization effect.

Therefore, it is recommended to choose diesel from regular gas stations that meets the required brand and quality standards, and regularly replace the fuel filter to ensure the cleanliness of the diesel.

Electronic system maintenance:

Electronic fuel injection diesel engines are equipped with complex electronic systems to control fuel supply and emissions, which have certain requirements for the operating environment.

In daily use, it is important to ensure that the electronic system of the engine is kept away from heat sources and to pay attention to waterproofing, dust prevention, and collision prevention.

Oil and filter replacement:

Electronic fuel injection diesel engines also have high requirements for engine oil, and CF or higher grade engine oil should be used. The oil filter should be replaced regularly to ensure the cleanliness of the engine oil and the good operation of the machine.

Coolant usage:

Due to the high heat load generated by the common rail in electronic fuel injection engines, the water temperature is prone to rise.

Therefore, coolant cannot be replaced with water. Antifreeze should be added according to the label in the accompanying manual to ensure good heat dissipation and avoid damage caused by high engine temperature.

Professional maintenance and upkeep:

In terms of repair and maintenance, electronic fuel injection diesel engines require professional testing equipment and tools, as well as maintenance personnel with solid professional knowledge and skills.

During maintenance, it is necessary to carefully investigate the fault, identify the root cause of the problem, and carry out effective repairs. If replacement parts are needed, original factory parts or standard parts should be selected.

In summary, electronic fuel injection diesel engines have a series of special maintenance requirements aimed at ensuring the normal operation of the engine and extending its service life. Therefore, car owners and maintenance personnel should fully understand these requirements and strictly follow them for maintenance and upkeep.
