Will Full Throttle Cause Engine Blowout?

[NolanRose]

Full throttle does not necessarily cause engine blowout. However, if the vehicle operates at such redline RPM for an extended period, the engine load will be relatively high, leading to a rapid rise in cylinder temperature and excessive pressure, which can easily result in engine blowout. Engine blowout occurs when the tachometer enters the red zone. Due to excessive heat, the piston expands and gets stuck in the cylinder, causing the engine to fail. In severe cases, the piston may become immobile due to excessive pressure, locking all four wheels of the vehicle and potentially causing flames to shoot out. Quick and effective methods to suppress detonation include retarding the ignition timing and reducing combustion pressure. The knock sensor operates by detecting engine detonation and then retarding the ignition timing to a point where detonation does not occur. Once the engine stops detonating, the ignition timing is gradually restored.
