Will Full Throttle Cause Engine Seizure?
1 Answers
If the vehicle operates at such redline RPM (i.e., full throttle) for an extended period, the engine load will be relatively high, leading to a sharp rise in cylinder temperature and excessive pressure, which can easily cause engine seizure. More related details are as follows: 1. Engine Seizure: This occurs when the tachometer enters the red zone. Due to excessive heat, the piston expands and gets stuck in the cylinder, resulting in engine failure. In severe cases, when the pressure is too high and the piston cannot move, it may cause the vehicle's wheels to lock up and even result in flames shooting out. 2. The Fastest and Most Effective Way to Suppress Detonation: Retard the ignition timing to reduce combustion pressure. 3. How Knock Sensors Work: When engine knock is detected, the ignition timing is retarded to a point where knocking stops. Once the engine stops knocking, the ignition timing is gradually restored. Knock sensors use accelerometers to measure changes in engine acceleration, i.e., vibrations. Engineers program the ECU with the vibration pattern of knocking. Once the knock sensor detects this pattern, the ECU identifies engine knock and immediately retards the ignition timing. More advanced knock sensors can even determine which specific cylinder is knocking and individually retard the ignition timing for that cylinder.
