ABSTRACT:
The piston of an internal combustion engine has an odd number of sockets formed in the top surface thereof. With the piston in its top dead center position, a thin slit is formed between the cylinder head and the top of the piston. The sockets form acoustical chambers for detonation waves which may be generated in the cylinder such that with the piston in its top dead center position, these detonation waves travel in random fashion between the acoustical chambers formed by the sockets thereby attenuating such waves and minimizing the effects of detonation.
