Q:The working principle of diesel engine fuel system

Fuel tank (fuel) - fuel pump (fuel supply) - fuel filter (pressure regulator excess oil back to the mailbox) - oil supply rail - fuel injector (jet)

Q:How the car fuel system is generally maintained.

Different varieties, different qualities of gasoline will lead to increased glial and moisture are also different. For example, China's current gasoline is divided into three categories, unleaded petrol, ethanol gasoline, methanol gasoline, unleaded petrol is also divided into three categories, four countries, three countries. Unleaded gasoline produces more gum and methanol and methanol, while ethanol and methanol gasoline are more likely to adsorb moisture. As the oil varies greatly, resulting in vehicles around the fuel system failure is not the same. Such as ethanol gasoline part of the owners generally reflect the fuel consumption of ethanol gasoline is greater than the original unleaded petrol, cold start effect is poor, gasoline pump abnormal sound and so on.

Q:The role of automobile fuel system

Give the engine sufficient fuel pressure

Q:What parts of the engine fuel supply system?

Engine fuel supply system components are: gasoline tank, petrol filter, petrol pump, oil and gas separator, tubing, fuel oil and other auxiliary devices!

Q:There are several parts of the car fuel system that define the parts

There are several parts of the car fuel system, the definition of fuel tank, fuel pump (electric, mechanical, electronic and other forms), to the tubing, oil return pipe, fuel filter, fuel rail, fuel pressure regulating valve, (After three on the EFI car). I am learning to repair the car, and this is also more understanding, hope to answer for you!...

Q:How the truck fuel system is depressurized

Some fuel rails above the relief valve, or pull the pump to start the vehicle until the flame, and then start a few times to relieve pressure

Q:What is the composition of the car fuel system?

Fuel tank, oil pump, oil compartment, tubing, oil return valve, nozzle

Q:Judgment and Solution of Common Faults in Automobile Fuel System

The most common faults in the fuel system are: oil pump aging (poor service). Fuel injector dirty block. Steam filter dirty block. Should pay attention to the regular replacement of gasoline filter. Use a good point of oil to check the fuel system is a problem. Pressure to see if the oil pressure is normal .. to check the oil pressure at idle. Acceleration of the oil pressure. After the flame .. Can determine the pump is not good. Oil is smooth. Bus filter is blocked. The simplest method can be judged by pulling out the plug of the injector, such as the apparent jitter of the engine after unplugging, indicating that the injector is working well, such as the engine no reaction, indicating that the injector is working poorly. Under the cleaning or replacement

Q:Is the petrol fuel supply system the same as the fuel supply system?

the same

Q:Why does the car clean the fuel system? What is the effect on the engine?

Cleaning can improve the cleanliness of the fuel system, so that fuel system fuel flow, reduce vehicle failure.
