What causes a gasoline engine to stall under load?
1 Answers
Gasoline engines stall under load due to engine carbon buildup or transmission overload operation. Here are the relevant explanations: 1. Engine carbon buildup: Carbon deposits cause incomplete combustion of gasoline, leading to engine stalling. Engine carbon buildup significantly affects vehicles: firstly, it reduces engine power, resulting in uneven power output and gradual decay. Secondly, it increases fuel consumption, adding to economic burdens. Thirdly, it causes difficult cold starts, making the engine hard to ignite. Severe combustion chamber carbon buildup can also lead to cylinder knocking, acceleration noise at low RPM, damage to pistons and crankshafts, and engine overheating, seriously compromising vehicle safety. Additionally, it results in excessive emissions, failing annual inspections and worsening environmental pollution. 2. Transmission overload operation: Overloading the transmission degrades transmission oil quality and friction characteristics, increasing friction and wear, leading to transmission noise. Simultaneously, sludge (impurities or contaminants) forms inside the transmission (e.g., in the valve body), causing symptoms like jerking, gear slipping, impact, slippage, stalling, abnormal noises, delays, overheating, and oil leaks. If not addressed promptly, the transmission may be permanently damaged.
