An internal combustion engine has at least one combustion chamber and a piston configured to reciprocate within the at least one combustion chamber between a top-dead-center position and a bottom-dead-center position. The internal combustion engine also has a pre-combustion chamber, an air induction system, a fuel system, a spark plug at least partially disposed within the pre-combustion chamber. The air induction system is configured to direct air into the at least one combustion chamber. The fuel system is configured to direct gasoline into the at least one combustion chamber. The spark plug is configured to selectively ignite a mixture of the air and gasoline. The internal combustion engine also has an exhaust system configured to direct exhaust from the at least one combustion chamber and an exhaust gas recirculation system configured to selectively redirect at least a portion of the exhaust from the exhaust system back to the air induction system.
