Abstract
A spark ignition internal combustion engine is equipped with a fuel pressure sensor for detecting a viscosity of fuel supplied to a fuel injector based on a variation in a fuel pressure. In a case of stratified combustion by a spray guided injection, an ECU advances a fuel injection start timing of the fuel injectoraccording to the detected viscosity of the fuel. Thus, even if the viscosity of the fuel is significantly high, the fuel-rich area is well formed at a vicinity of the discharge electrode so that a preferable combustion condition can be maintained.
