2. Which components do air and fuel flow through in sequence throughout the entire operation of the engine fuel injection system? _Hundred The electronic control injection system includes an air supply system, a fuel supply system, and an electronic control system. The air supply system can supply appropriate intake air to each cylinder according to the engine operating conditions, and has a flow meter and a crankshaft speed sensor to calculate the fuel injection amount. The intake sequence of the engine in non rapid conditions is as follows: intake port 1>air filter (air flow meter calculates intake volume) ->intake throttle tube 1>throttle valve 1>intake manifold 1>valve train intake valve 1>combustion chamber. The key components of the fuel supply system are the fuel required for the formation of the mixture, which consists of the cars fuel tank, fuel pump, return pipe, and pressure regulator. The direction of fuel flow is plastic car fuel tank ->gasoline pump ->rubber fuel pipe ->filter ->injector, and the excess high-pressure gasoline falls back into the car fuel tank.

What are the common problems of B12 engine? The common problems of B12 engine are mainly reflected in two aspects: unstable idle and weak acceleration. Idle instability refers to the phenomenon where the engine speed fluctuates significantly while the vehicle is stationary, making it difficult for the vehicle to operate steadily. And weak acceleration is manifested as slow power response of the vehicle during acceleration, unable to quickly increase speed. As the core component of a car, the engine has a crucial impact on the power, economy, stability, and environmental friendliness of the vehicle. According to the different sources of power, automotive engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines. Among them, reciprocating piston internal combustion engines are a common type, which convert the chemical energy of fuel into mechanical energy to provide power for automobiles. The unstable idle of the B12 engine may be caused by malfunctions in key components such as the throttle valve, air flow meter, and ignition system. The damage or aging of these components may lead to issues such as abnormal air flow and inaccurate ignition timing, which in turn can affect the stability of the engine speed. And weak acceleration may be due to malfunctions in components such as valves, injectors, and intake systems, leading to an imbalance in the mixing ratio of fuel and air, which affects the power output of the engine and engine. To effectively address these issues with the B12 engine, car owners should regularly maintain and inspect the engine. For example, regularly replacing vulnerable parts such as air filters, ignition coils, spark plugs, etc., to ensure the normal operation of the engine. At the same time, paying attention to engine maintenance, such as regularly changing oil and filters, keeping the engine clean and lubricated, can help extend the service life of the engine. In short, unstable idle and weak acceleration of B12 engine are common problems that require regular maintenance and inspection to ensure the normal operation of the engine. Car owners should pay attention to these common issues and take appropriate measures to prevent and solve them.
