Does the Suzuki Handao 150 engine experience piston slap?

[McBraxton]

Not necessarily, piston slap is not a common phenomenon. Piston slap in a car is a type of malfunction caused by premature ignition. When the piston has not yet reached the top dead center, the diesel engine has already injected fuel into the cylinder. This causes combustion while the piston continues to move toward the top dead center, producing a knocking sound. This is the phenomenon of piston slap in a car. Additional information: 1. Piston slap: (1) Piston slap is the most significant abnormal combustion in an engine, often occurring when the compression ratio is high. (2) When it occurs, the engine produces a high-frequency metallic knocking sound, hence it is also called detonation. 2. Effects of piston slap: (1) When piston slap is mild, the engine power may slightly increase. (2) In severe cases, power and RPM decrease, operation becomes unstable, the engine shakes severely, and it may cause the engine to overheat and emit black smoke.
