1. Function of engine intake system

The engine intake system consists of three parts: an air filter, an intake manifold, and an air flow meter. It mainly has the following three functions

1. Filter out impurities or dust in the air, providing clean and fresh air into the cylinder

2. Provide a suitable concentration of mixture

3. The difference between aerodynamic force and cleanliness. 4. Due to the different ignition methods, diesel engines rely on compression ignition. Compression ignition refers to the pressure detected by the piston in the cylinder, which causes diesel to self ignite under pressure. This requires a large compression ratio, in other words, the depth of piston compression is very deep. This makes the output torque of diesel engines greater than that of gasoline engines. High torque does not affect the vehicle speed, but it can affect the instantaneous acceleration and load capacity of the car. Therefore, many utility vehicles use diesel, which means they are powerful. Additionally, all diesel engines are turbocharged. This is also a characteristic

5. Cleanliness: Diesel is a clean fuel in foreign countries because of its relatively clean emissions and low fuel consumption, which has led many large displacement cars abroad to choose diesel. But in China, on the contrary, diesel is an unclean fuel. Why is that. Because domestic diesel contains a relatively high amount of wax. Wax is prone to precipitation and condensation, clogging oil pipes and exhaust systems, and causing pollution in emissions. So many cities in China prohibit passenger cars from using diesel systems. The simple return air or clean air mixed with gas and fuel should be evenly and fully distributed to

2. What is the reason why an electronic fuel injection diesel engine suddenly stalls and cannot start?

The reason why the electronic fuel injection diesel engine suddenly stalls and cannot start is due to insufficient battery power or battery failure, fuel system failure, or air flow meter failure..

1、 Low battery level or battery failure: Electronic fuel injection diesel engines require power supply to function properly. If the battery level is low or the battery malfunctions, it will cause the engine to fail to start. You can check if the battery is charging properly or replace it with a new one.

2、 Fuel system failure: The fuel system of an electronic fuel injection diesel engine includes components such as a fuel pump, fuel filter, and fuel nozzle. If any of these components fail, it will cause the engine to fail to start. You can check whether the fuel pump is working properly, or clean and replace the fuel filter and fuel nozzle if it is stuffy.

3、 Air flow meter malfunction: The air flow meter is an important sensor in electronic fuel injection diesel engines, which measures the amount of air entering the engine and provides data to the electronic control unit. If the air flow meter malfunctions, it will cause the engine to fail to start. You can check whether the air flow meter is damaged or blocked, and clean or replace it. Introduction to the characteristics of electronic fuel injection diesel engine. Electronic fuel injection diesel engine is an engine that adopts electronic control fuel injection system, which has the advantages of high efficiency, environmental protection, and economy. The working principle of an electronic fuel in
