Abstract

The application describes a system for an engine comprising a direct injection nozzle for injecting gaseous fuel into a cylinder of an engine in a second operating mode; an intake injection nozzle for injecting liquid fuel into an intake port of the engine in a first operating mode; and a valve gear suitable to adjust timing of opening and closing of an inlet valve. Preferential injection of a gaseous fuel such as compressed natural gas directly into the cylinder increases efficiency and allows for reduced heat exposure to the lesser used liquid gas injectors mounted in the intake port, reducing coking of these injectors.
