What is the fuel supply system? Kero Throttle Valve give you the answer:

    As the name implies, refers to the system for supplying combustible gas mixture apparatus. Of course, due to the different fuel supply method will be different. Such as gasoline is supplied to the engine according to the requirements of the preparation of a certain number and concentration of the mixture supplied into the cylinder, and the exhaust gas after combustion is discharged from the cylinder to the atmosphere.

    The role of the fuel supply system

    The role of the fuel supply system are: the cylinder is supplied to the combustion of gasoline needed.

    Composition of the fuel supply system

    Fuel supply system includes a fuel tank, fuel pump, fuel buffers, fuel pressure regulator, fuel filter, fuel injectors, thermostat timer switch and cold start valve (cold start injector) and other components.

    Fuel tank (fuel tank) ---- save fuel use.

    Fuel pump (electric fuel pump) ---- whose role is to pump the fuel from the fuel tank fuel line people, and to maintain a certain pressure of fuel through the fuel injector cleaner and transported to the cold start valve.

    Fuel pump mounting location into their exterior and interior pump pump pump upcoming two exterior pump installed in the pipeline path outside of the tank, built pump sucked pump installed in the fuel tank. Compared with the exterior pump, it is not easy to produce vapor lock and fuel leakage and noise. Most EFI uses built-in pump.

    Fuel buffer ---- also known as pulsation dampers. Its role is to make the fuel pump to pump out the oil pressure becomes stable, reducing pumping pressure fluctuations and reduce noise.

    According Kero Throttle Valve noted, the fuel pressure regulator ---- the oil pressure regulator is installed, it makes the fuel pressure relative to the popular pressure or negative pressure to maintain a certain intake manifold, fuel injection pressure and injection that maintain pressure on the environment The difference certainly. This pressure difference is generally maintained at 250kPa, when the supply pressure exceeds a predetermined value, the pressure regulator valve in the open, gas will flow back into the tank through the return pipe, so that the hydraulic pipeline is kept constant.

    Fuel Filter ---- mounted on the oil with the fuel injector slow secondary between, its role is to filter the fuel moisture and impurities such as dirt, to prevent clogging injectors meter valve.

    ---- Injector mounted on the throttle body injector air entrances (SPI system) or near the intake manifold near the intake valve of each cylinder (MPI system), fuel injection control signal by the electronic controller, which powered by a fuel injector fuel injection quantity determines the length of time, thus the amount of fuel into a mist sprayed into the intake manifold.

    Injector injector principle is: the electric current injection signal sent from the controller, the current flowing through the electromagnetic coil generates an electromagnetic suction, the suction attracting core, the core formed integrally with the needle, the valve is opened at this time count, emitted by the fuel injector.

How engine fuel system cleaning?

    As the automotive fuel distribution system is very sophisticated, not just dismantling. When cleaning the engine fuel system, use the engine to avoid demolition cleaning agents, cleaning agents to avoid demolition because with no need to disassemble the fuel system, one can start to effect thorough cleaning of the fuel system, on the other hand will help protect the engine fuel system .

According Kero Throttle Valve understand it, to avoid demolition cleaning agent and the oil tank operation process:

    1, open the fuel tank cap, remove the filter cartridge, pull out most of the fuel tank with a hose inside, leaving about 10 to 15 cm deep in the fuel, and add 80ml of ethanol to replace gasoline detergent, and put on the filter canister and lid the fuel tank cap.

    2, open the engine intake, return pipe, the engine inlet pipe and return pipe with free demolition washing machine inlet pipe and return pipe is connected to a dedicated interface with inlet pipe and the return pipe to form a loop.

    3, according to the scale or the engine to avoid demolition cleaning cylinders (100ml per cylinder gasoline) engine oil tank of gasoline storage tanks add detergent and add 100ml of ethanol to replace gasoline detergent.

    4, according to the model to adjust the pressure, the pressure can be appropriately adjusted carburetor cars, EFI car to adjust the pressure of 2-3.

    5, start the engine and check into the return pipe for leaks, cleaning 15-20 minutes at idle speed, increase the throttle once every 3-5 minutes, so that the cleaning of carbon and water discharged from the exhaust pipe.

    6, free split apart into the washing machine with the engine, return pipe, the oil recovery car, start the car to check the tubing for oil leaks.

    7, open the tank cover and remove the filter cartridge; trachea with valuables pump is turned on, the hose from the tank port into the bottom of the tank to purge 3kg/cm pressure, so that the bottom of the tank accumulation of various impurities are churning Gasoline cleansed. During cleaning, the best on the block with a clean cloth tank port, and continue to move the hose purge position.

    8, when it is confirmed at the bottom of the tank was blown clean of impurities, such as immediately after the release of the full tank of oil. Remind the release of crude oil tank must be after the precipitate was filtered and then added to the tank.

    9, replacing the fuel filter (depending on the specific circumstances).

    10, adding ethanol gasoline or regular gasoline, start the engine, road test.
