DIRECT INJECTION INTERNAL COMBUSTION ENGINE WITH A MULTIPOINT SPARK PLUG INTEGRATED WITH AN INJECTOR, WHICH TAKES LITTLE SPACE

摘要

PURPOSE: A direct injection internal combustion engine with a multipoint spark plug integrated with an injector is provided to improve thermal efficiency as the speed of burning fuel increase.;CONSTITUTION: A direct injection internal combustion engine comprises a cylinder head(10), a spark plug(30), and a injector. The spark plug comprises positive and negative electrodes. The spark plug is installed in the cylinder head in order that the positive and negative electrodes are exposed to the center of a combustion chamber. The injector is fixed into an injector space formed in the spark plug to inject fuel to the center of the combustion chamber. The spark plug comprises positive and negative electrode plugs.;COPYRIGHT KIPO 2013
