Why does a diesel vehicle lack power and can't run properly?
1 Answers
Diesel engine lack of power may be caused by engine failure, requiring inspection of the diesel engine's intake system, exhaust system, and fuel supply system for proper operation. Below are relevant explanations for diesel engine power loss: 1. Most trucks are equipped with manual transmissions: Manual transmissions have a clutch, where the clutch pressure plate is fixed to the engine flywheel, and the clutch disc transmits power when pressed by the pressure plate. If the clutch disc is not pressed tightly, it will slip during acceleration, preventing full power transmission to the transmission, resulting in weak vehicle acceleration; 2. Poor spray quality: Less oxidation reaction occurs, leading to reduced heat generation. Additionally, if the diesel engine governor is improperly adjusted or the governor spring is too tight or broken, it may result in insufficient force to push the fuel pump rack, preventing the injection pump from increasing fuel supply, thereby causing diesel engine power deficiency.
