摘要： An auxiliary combustion chamber at least partially embedded in the cylinder head of an internal combustion engine adjacent the intake valve of a main combustion chamber and having a spark plug positioned in the auxiliary chamber and unvalved inlet and outlet ports interconnecting the auxiliary chamber with the main chamber. The air/fuel mixture drawn into the main combustion chamber is deflected by the back surface of the intake valve into the inlet port of the auxiliary combustion chamber toward the spark plug. The auxiliary combustion chamber may include a shell positioned in a cavity in the cylinder head with devices for properly positioning the shell in the cavity and for retaining the shell and preventing it from rotating. A passage is provided for rich air/fuel mixture terminating at the rear surface of the valve, when closed, with refinements of the passage, shape of the inlet port, and main combustion chamber wall facilitating the flow of the rich mixture into the auxiliary combustion chamber by venturi action. The flow of fresh mixture into the auxiliary combustion chamber through suction scavenges the combustion gas remaining from the prior firing sequence.

摘要： A cam lobe 22 is formed as a single part, not formed together with a shaft body 21. The shaft body 21 penetrates through bearing holes 13F, 13M, and 13R, as well as a mounting hole 24 provided in the cam lobe 22, which is arranged in between the adjacent bearing holes 13F, 13M, and 13R. The bearing holes 13F, 13M, and 13R each in a perfect circular shape can be achieved, since there is no need to divide the bearing holes 13F, 13M, and 13R into two semi-circular arc shaped concave portions. Consequently, a camshaft 20 can be supported so as to rotate smoothly.
