HCCI FUEL INJECTORS FOR ROBUST AUTO-IGNITION AND FLAME PROPAGATION

摘要

A direct injection engine includes a fuel injector receiving a flow of pressurized fuel. The fuel injector provides fuel injections directly into a combustion chamber of the engine. The fuel injector includes a first fuel injector nozzle opening directing with a first narrow injection angle a first portion of a fuel injection mass at a spark gap of a spark plug. The fuel injector further includes a second fuel injector nozzle opening dispersing with a second wider injection angle a second portion of the fuel injection mass within the combustion chamber.
