Abstract

Various systems and methods for determining a start of fuel injection including a gaseous fuel in an internal combustion engine are provided. In one embodiment, an end of gas injection, a duration of gas injection, and a start of gas injection in an induction pipe of a cylinder of an internal combustion engine is determined based on one or more operating parameters. An earliest possible start of gas injection is further determined, and if the start of gas injection is before the earliest possible start of gas injection, at least one of the one or more operating parameters is modified such that the start of gas injection does not occur before the earliest possible start of gas injection.
