The function and the components in fuel system The function of the fuel system is to supply a certain amount of clean, well-atomized gasoline to the engine according to the operation condition of the engine, in order to mix with a certain amount of air to form a combustible mixture. At the same time, the fuel system also needs to store a considerable amount of gasoline to guarantee the car's Limited driving distance. The fuel system includes the electronic fuel injection system, the fuel supply system (fuel tank, fuel filter, fuel pump, fuel and fuel separator, fuel supply line,fuel gauge and other auxiliaries.

The electronically controlled gasoline injection system has many wires and connectors, often with broken wires or shorted overlays, loose connectors, poor contact, so that the engine does not work or does not work, but also causes many sensors, poor transmission of control signals of the executive components, resulting in the engine does not work properly.

The function of the fuel system is to supply a certain amount of clean, well atomised petrol to the engine in order to mix with a certain amount of air to form a combustible mixture, according to the operating conditions of the engine. At the same time, the fuel system needs to store a considerable amount of petrol in order to ensure that the car has a considerable driving range.

The function of the fuel system. Automobile fuel system includes: carbureted fuel systems，gasoline engine fuel injection system(gasoline injection systems), gasoline engine direct injection fuel system, traditional diesel system, diesel engine fuel injection control system, etc. Carbureted fuel systems has been phased out. The following is an example of gasoline injection systems. Modern gasoline injection systems are controlled electronically, due to the fuel quantity and quality can be set to suit the engine operating conditions accurately. In this article, will briefly introduce the components and the function of the fuel system

Fuel pump is responsible for feeding fuel to engine, if it does not work, the car will not work. We will show how to check the car fuel pump. Tools: Multimeter Methods/Steps Check the fuel pump step 1 Open the tank cap and turn on the ignition switch. If you can hear the sound of pumping fuel for 3 to 5 seconds, it shows the fuel pump and circuit work normally.

Engine oil pump belongs to a kind of hydraulic pump, in fact, there are many hydraulic pumps in the car. Common hydraulic pumps are external gear pumps, internal gear type pumps, rotor pumps and vane pumps. In terms of oil pumps for automotive lubrication systems, external gear pumps, internal gear pumps and rotor pumps are commonly used.

After measuring the static fuel pressure for 5min, observe the value of the fuel pressure gauge. At this time, the pressure is called the fuel system fuel holding pressure. Its normal value should be no less than 147kPa. If the fuel pressure is too low, check the holding pressure of the electric fuel pump, the holding pressure of the fuel pressure regulator and the leakage of the fuel injector.

The fault of fuel supply system accounts for a large proportion in electric ejection engine, among which the fault of fuel pump is quite common. Based on the analysis, elimination and summary of many cases of fuel pump faults, there are mainly two kinds of fuel pump faults: the fuel pump motor is broken and the fuel supply is insufficient. In this article we will discuss how to diagnose a faulty fuel pump. Fuel supply system fault accounts for a large proportion in the ejection engine, one of fuel pump fault is relatively common in fuel supply system. Based on the analysis, elimination and summary of many cases of fuel pump faults. There are mainly two kinds of fuel pump faults: the fuel pump motor is open circuit and the fuel supply is insufficient. we will diagnose the faulty fuel pump. Fuel pump fault ; diagnosis; fuel supply system; ejection engine; fuel pump fuel supply; pump motor; large proportion; fuel pump is the primarily elements and will be discussed in this article.

Replacing the fuel pump does not require dismantling the engine. As the most basic component of the engine fuel supply system, the petrol pump is responsible for pumping fuel from the fuel tank during engine operation and continuously delivering it to the engine through the supply line at a certain pressure.

The car petrol pump is recommended to be replaced at 80,000 to 100,000 km, because the petrol pump assembly is a petrol pump plus petrol filter composed together and installed in the fuel tank. If the car is driven for a long time with the fuel alarm light on, it will cause the temperature of the petrol pump to be too high and affect its service life.
