Abstract:
A direct cylinder injected, internal combustion engine comprising a plurality of cylinders each having a combustion chamber, an air induction system for delivering an air charge to said respective combustion chambers, a plurality of fuel injectors being provided for said respective combustion chambers for injecting fuel directly into said combustion chambers for burning with the air charge delivered by said induction system, an exhaust system for discharging the burnt charge from said combustion chambers, and a control device for separately controlling at least an injection timing of each one of said fuel injectors such that said injection timing of each one of said fuel injectors can be independently adjusted based on engine operating characteristics and said control device shifting the respective injection timings of said cylinders relative to each other so that at least one of the state of emissions contained in the burnt charge and the state of fuel efficiency is almost optimal in every cylinder.
