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

The role of the fuel system is the engine for the different conditions: temperature, speed and timely and accurate to provide the best air-fuel ratio required gasoline.

Q:Fuel system if there is no fuel, how can judge it

Hello, fuel systems include fuel tanks, petrol pumps, petrol pressure regulators, petrol filters, fuel injectors and oil pipelines. According to the situation detection. I hope I can help you.

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

The main reason is the fuel itself contains glial, impurities, dust, moisture, etc., over time in the fuel tank, into the tubing and other forms of sludge and other sediments; followed by the oil and gas, As the volatile components of olefins and other unstable components in the high temperature oxidation and polymerization reaction, the formation of colloidal and resinous viscous material, the sticky material to stay in the nozzle, intake valve and other parts of the sediment when the sediment Will become a hard carbon deposition. In addition, traffic congestion, cars are often in the low speed and idle state, but also increase the formation of carbon deposition and sediments. Fuel system does not clean will cause a lot of harm to your car: First, carbon deposition and sediment will plug the nozzle needle valve, valve hole, the impact of precision parts of the jet system performance, resulting in poor fuel injection, Power performance and so on. Second, carbon deposition and sediment will cause the intake valve to close lax, cylinder pressure drop or even tempering, resulting in engine idle instability, fuel consumption and accompanied by deterioration of exhaust emissions. In the piston and cylinder head and other parts of the carbon deposition, easy to make the combustion chamber local overheating, gasoline preheating caused by engine knock and other failures. These faults will shorten the engine life. Therefore, regular maintenance of the fuel system is important.

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

the same

Q:What is the engine fuel line system

Hello, the fuel supply system is the role of: to the cylinder to supply the necessary gasoline combustion. Fuel supply system includes fuel tank, fuel pump, fuel buffer, fuel pressure regulator, fuel filter, injector, temperature timer switch and cold start valve (cold start injector) and other components.

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

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

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 long the car fuel system is cleaned is not a car without failure can not be cleaned

In fact, there is no need to clean.

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
