Abstract:
One advantage of a direct-injection S.I. engine is lower fuel consumption due to the use of lean stratified charge combustion. Another advantage is greater power output resulting from evaporation of the fuel in the cylinder. A critical factor in making the most of these advantages is to achieve optimum mixture formation for both stratified and homogeneous charge combustion.To achieve the optimum mixture, the new direct-injection S.I. V-6 engine adopts a piston with a shallow bowl, a valve that changes in-cylinder air motion between swirl and tumble by opening and closing one side of separated air intake port, an air intake port that has optimized inward and port angle to induces swirl in the piston bowl, and a CASTING NET injector that injects the hollow cone spray in a deflected pattern toward the spark plug.
