ABSTRACT:
An externally ignited four cycle internal combustion engine equipped with an inlet valve and an outlet valve, both valves being positioned on one side of the cylinder. A swirl (or vortex) chamber is provided within the cylinder head, the height of the swirl chamber being substantially less than its maximum diameter. The inlet and outlet valve discs lie substantially in a same plane. A channel-like recess in the cylinder head, which creates a guide channel when the piston is in its upper dead center position, terminates approximately tangentially in the swirl chamber.
