 1. The car is weak in acceleration and the car cannot run. It is better if the speed exceeds 2500 rpm;
2. The car will have high fuel consumption, excessive exhaust emissions, and unpleasant black smoke will be emitted from the exhaust pipe;
3. After the engine fault light detects that the sensor is faulty, it will light up the fault light to remind the owner to carry out inspection and maintenance;
4. The idling speed of the car is unstable and the vibration is serious, similar to the failure of the car lacking cylinder;
5. During the start-up process, the crankshaft will be reversed, and there will be a tempering phenomenon in the intake manifold. The camshaft is a component in a piston engine that controls the opening and closing of the valve.
Although the camshaft rotates at half the speed of the crankshaft in a four-stroke engine, it is usually still very high and requires a lot of torque.
