Abstract

An internal combustion engine includes transfer passages between a pre-chamber and a main combustion chamber, and a control unit configured to control a pre-chamber supply system coupled to the pre-chamber and a main combustion chamber supply system coupled to the main combustion chamber, wherein the control unit is configured to control the pre-chamber supply system such that a supply volume exceeds a volume of the pre-chamber and that a surplus of the supply volume is communicated to the main combustion chamber, such as during a transient operating condition.
