Why does the Magotan engine shake when started?

[McJasmine]

Here are the specific reasons for the Magotan engine shaking when started: 1. Shock absorber system failure: The shock absorber system is mainly responsible for filtering the vibration of the engine during operation. If there is a problem with the shock absorber, these vibrations will be directly transmitted to the steering wheel and the interior of the car, affecting driving. When the engine is idling, turning on the electrical system in the car can also easily cause shaking. The engine increases the load due to the activation of electrical appliances, causing the idle speed to drop. To compensate for the shaking caused by the idle speed drop, the engine will automatically increase the speed. 2. Unstable oil pressure: Check whether the fuel supply pressure and intake pressure sensor are normal. If the fuel pump supply pressure is abnormal or the intake pressure sensor value is incorrect or not working properly, it will cause the car body to shake. 3. Cold start: The main reason for the car body shaking during a cold start is insufficient fuel combustion, which leads to insufficient power of the car. The ignition energy is low. When starting, when the temperature of the fuel and lubricating oil is low, it is necessary to rely on more fuel to meet the power demand. Over time, the gap between the poles of the spark plug will gradually increase, leading to a decrease in ignition energy and poor fuel atomization, which will cause the car body to shake. In addition, aging of the ignition coil, aging of the high-voltage wire of the spark plug, or leakage can also lead to a decrease in ignition energy.
