ABSTRACT:
An externally ignited four cycle internal combustion engine equipped with an inlet valve and an outlet valve. In one embodiment a swirl (turbulence or vortex) chamber is provided within the cylinder head, the height of the swirl chamber being less than its maximum diameter. An outlet closable by the outlet valve is located in the upper portion of the swirl chamber. A channel-like recess, which creates a guide channel when the piston is in its top dead center position, terminates approximately tangentially in the swirl chamber. The channel-like recess may be formed in the cylinder head, in the top of the piston or partially in both of these members. In another embodiment, a reduced throat area is adapted to introduce the gases from the first inlet valve chamber to an oval secondary chamber adjacent to the outlet valve.
