Oil control valve and engine power relationship
Throttle sinking and poor engine acceleration are related to oil control valves. The oil control valve is also known as the variable timing control valve, and the variable timing system of the car can be adjusted according to the engine speed and throttle opening, so that the engine can obtain sufficient intake and exhaust efficiency regardless of the low speed and high speed.
The acceleration of the car is related to the intake volume through the intake pipe per second, if the intake volume is not enough at low speed or the exhaust is less at high speed, it will cause the mixture distribution to be uneven, and the dynamic response will be slow, so the two factors mentioned in the question are related.
The air supply system is faulty
The fuel control system of the engine is a highly concentrated combination of mechatronics, consisting of multiple sensors, actuators and engine control units. When the control system works, the sensor signals are cross-transmitted to jointly control the ignition, fuel injection and air intake.
Ignition system failure
Ignition system is mainly inaccurate ignition time, resulting in early engine ignition or knock. If the ignition advance Angle is too late, it will cause the engine to burn slowly, then the engine power can not be provided, and other reasons may be that the spark plug jump spark is weak.
Fuel system failure
The fuel system failure is mainly caused by three reasons, one is the pressure valve above the tank cover is damaged, due to the blockage of the vent hole above the tank cover, making the vacuum in the tank, the gasoline can not be pumped out, when the accelerator is pressed, the engine power supply is not on. The second reason is that the octane number of the gasoline is too low to cause the engine to knock. The third reason is that the system's high-pressure oil pump or fuel assembly is damaged.
The variable timing control system of the engine can change the time when the valve is open, but it cannot change the amount of air intake. This system can adjust the intake volume supplied to the valve according to the load and speed of the engine, and obtain good intake and exhaust efficiency.
