fuel gauge tank float level sending unit for 1990 - 1993 honda accord
Honda fuel metering system fault level is not accurate：In this case, the display system of the fuel gauge or the measuring system may be faulty. The fuel gauge has two systems, one is the display system and the other is the measurement system. The display system shows how much fuel is left in the tank, and the measurement system measures how much fuel is left in the tank. To put it simply, the signal of the measuring system is sent to the display system, which is displayed by the fuel gauge.
If The fuel tank buoy is faulty. How to repair it?
When the seal fuel float fuel tank fails (generally the float valve is jammed and loses its regulating function), it should be immediately removed from operation and replaced with bypass fuel drainage. At this time, the opening of the bypass valve shall be operated according to the liquid level indication on the bypass to maintain the fuel level. It shall be held in the middle of the observation window and must be closely monitored. Because the fuel level gradually increases, the hydrogen side fuel drain tank may overflow into the generator; If the fuel level is too low, the "fuel seal section" of the pipeline may be damaged, resulting in H2. A large amount of leakage leaked into the air extraction tank (at this time, the hydrogen pressure in the generator may drop sharply). Therefore, after the float fuel tank is out of service, it should be repaired as soon as possible to restore normal operation as soon as possible
If the cause of the fault is that the fuel quality is poor, resulting in the increase of carbon deposits on the injector orifice and valve, resulting in poor atomization of the injector and low fuel injection rate lower. Deposits on the intake manifold will affect the intake of the engine, affect the control accuracy of the air-fuel ratio of the mixture, and thus affect the normal operation of the engine. At the same time, due to poor fuel quality, the deposit after combustion causes poisoning and failure of the three-way catalyst and oxygen sensor, resulting in abnormal engine emissions. The white powdery substance around the exhaust pipe of the rear bumper of the car body is the product of combustion of silicon with excessive content in the fuel. For vehicles with Eurotron emission standard. The sulfur content of gasoline is required to be less than 0.005% (mass percentage). The sulfur in fuel will increase ignition hysteresis, increase ignition temperature and reduce engine power. Poison the three-way catalytic converter to failure and corrode metal parts. The olefin content of Class II unleaded gasoline is required to be less than 20% (volume percentage), and the olefin is unsaturated. The mixture of carbon and hydrocarbon can improve the octane number, but after being heated, it will form a gum deposit in the air intake system and fuel supply system, forming a blockage and causing emissions
deterioration, power reduction and fuel consumption increase.
