Claims

[Scope of utility model registration request]

A combustion chamber is defined by the cylinder block that forms the cylinder hole, the piston that is slidably housed in the cylinder hole and has a cavity formed on its top surface, and the inner wall of the cylinder that is fixed to the cylinder block and the top surface of the piston. In an engine, the engine includes a cylinder bed formed of a cylinder bed, and a spark plug attached to a cylinder head, wherein the spark plug protrudes into a squish flow generated in a combustion chamber during a compression stroke. An engine that is specially designed to have a deflector that deflects it.
