Dual spark plug ignition internal combustion engine having improved cylinder head configuration

Patent ·
OSTI ID:6284504
;

Intake and exhaust valves and an intake port of an internal combustion engine are arranged so that strong swirl turbulence of the inducted air-fuel mixture is produced in the combustion chamber. The swirl turbulence improves the combustion of the air-fuel mixture mixed with exhaust gases, initiated by the ignition with two spark plugs disposed in the combustion chamber.
