What if the Great Wall Feng Jun 5 refuels slowly?

The solution for the slow response of the Great Wall Feng Jun 5 refueling is as follows: 1. Air intake system: the air supply system mainly provides air suitable for fuel, and the purity of air restricts the combustion effect and indirectly affects the power supply. When the acceleration is weak, it is first necessary to judge whether the air intake system is in good condition. If it is in good condition, it is necessary to consider whether the air intake system needs cleaning. Remove the air filter and blow off the dust. If it is difficult to blow out, it should be replaced. Check whether the throttle valve is clean, and further check the intake valve intake manifold. 2. Fuel supply system: the supply of fuel directly determines the strength of power, and the full combustion of fuel and the amount of fuel are the guarantee of power. When the power is insufficient, the fuel supply system should be considered. First of all, we must ensure that the engine oil meets the fuel standard of the vehicle. Under the condition that the oil circuit and joint are intact, check whether the fuel filter, injector and fuel pump have poor oil supply, and clean or replace them if necessary. 3. Electronic control components: the sensors installed at each monitoring point transmit the monitoring data to the ECU, and the ECU identifies and analyzes it according to the preset program, and selects appropriate commands to transmit to the actuator. In this way, the car can drive according to the driver's wishes. When the air intake system and oil supply system are normal, the acceleration is still weak, that is, the electronic control is faulty.
