What Causes the Engine Abnormal Noise in Magotan?

[LaArabella]

Magotan engine abnormal noise mainly has the following reasons: 1. Piston slap noise: The so-called piston slap noise refers to the abnormal noise generated when the piston side knocks against the cylinder wall. Generally speaking, when the direction of the axial force on the piston top changes as the piston moves from the compression stroke to the power stroke, piston slap noise will occur. 2. Crankshaft bearing (big end) and connecting rod bearing (small end) noise: These two types of noise can be distinguished first by the sound location and frequency. Generally, the big end produces a lower-pitched sound, while the small end produces a higher-pitched sound. 3. Intake and exhaust system noise: When there is an intake manifold leak, the engine will produce noise during idle operation, and the noise will intensify as the engine speed increases.
