ABSTRACT:
A combustion system for a direct-injection, spark-ignition engine is disclosed. A side-mounted fuel injector located outboard the intake valves directs multiple fuel jets into a shallow, spherical bowl formed in a domed piston. Both good mixing to facilitate good air utilization with early injection and an ignitable mixture at the spark plug with late injection to facilitate cold start are provided with such a combustion system. Because the bowl is smooth and shallow, the surface area of the combustion chamber is less than with a deeper bowl of complicated shape. Lowering surface area in the combustion chamber leads to improved fuel economy.
