What Causes Shaking During Semi-Clutch Start in Trucks?
1 Answers
Truck shaking during semi-clutch start is caused by poor cylinder combustion and low ignition energy. The following are specific analyses: 1. Poor cylinder combustion: The fundamental reason for truck shaking is poor combustion inside the cylinder. Poor combustion results in insufficient power output, leading to vehicle shaking. 2. Low ignition energy: When the engine temperature is too low, the temperature of fuel and lubricating oil will also be insufficient. The larger the spark plug gap, the smaller the ignition energy. At low temperatures, fuel atomization is poor, requiring higher ignition energy. When the spark plug gap increases, it leads to decreased ignition energy, affecting power output and causing the vehicle to shake.
