Claim:
An internal combustion engine, comprising: at least one combustion chamber; a piston slidably disposed within the at least one combustion chamber and configured to reciprocate between a top-dead-center position and a bottom-dead-center position; a pre-combustion chamber in communication with the at least one combustion chamber; an air induction system configured to direct air into the at least one combustion chamber; a fuel system configured to direct gasoline into the at least one combustion chamber; a spark plug at least partially disposed within the pre-combustion chamber and configured to selectively ignite a mixture of the air and gasoline; an exhaust system configured to direct exhaust gas from the at least one combustion chamber, the exhaust gas divided into two streams, a first stream directed upstream of a turbine and away from an exhaust gas recirculation system; and a second stream directed to the exhaust gas recirculation system configured to selectively redirect at least a portion of the exhaust gas from the exhaust system back to the air induction system.
