How to Solve Gasoline Engine Overspeeding?
2 Answers
For gasoline engines equipped with power output clutch devices, disengage the clutch to prevent damage to attached equipment. For models using point ignition, ground the stop wire by contacting it with the engine body. Quickly remove the spark plug protector to cut off the gasoline engine's circuit. Cover the air filter housing with a cloth to block the gasoline engine's intake passage until the engine shuts down.
If the gasoline engine speed suddenly surges out of control, my first thought is safety first. Immediately pull over, turn on the hazard lights, and manually shut off the engine to prevent runaway risks. If the throttle pedal gets stuck, try gently tapping it or check if the cable is frozen or clogged with dirt—common in winter, sometimes a temporary DIY lubrication can help. But in most cases, it's best to turn off the engine, wait a few minutes for cooling, then attempt a restart. After confirming no fuel leaks or ECU malfunctions, call a tow truck for professional repair. For prevention, I regularly clean the throttle mechanism and inspect pedal free play every six months; extra attention before highway driving avoids sticking issues—developing this habit minimizes accidents.
