Abstract
An internal combustion engine includes multiple fuel injections external to a pre-chamber. A further aspect provides an engine pre-chamber ignition apparatus which employs a pre-assembled and/or removable cartridge including an ignitor and a fresh air inlet but not a fuel inlet injector directly mounted thereto. Another aspect of a vehicular engine apparatus includes a fuel injector positioned externally to a pre-chamber which delivers an initial greater quantity of fuel for combustion and then a later and smaller quantity of fuel for pre-chamber ignition.
