What Causes the Engine to Feel Sluggish and Fail to Accelerate When the Throttle is Pressed Hard?
1 Answers
When a car feels sluggish and fails to accelerate upon pressing the throttle, it may be caused by excessive engine oil, overly viscous engine oil, malfunctioning sensors around the engine, or issues with the transmission system. In a car, the engine provides power, and the transmission system is responsible for transferring the power generated by the engine to the wheels. If there is a problem with the transmission system, acceleration issues may occur when the throttle is pressed. Below are the functions of engine oil: 1. Friction Reduction: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing: Engine oil can form a seal between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering. 3. Rust Prevention: Lubricating oil can adhere to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston pin, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, and the flow of the lubricating oil washes away dirt generated on the working surfaces of the parts.
