Fremdgezündeter Verbrennungsmotor mit Direkteinspritzung

摘要

A direct injection engine provided with an injector (15) at a peripheral portion of a combustion chamber to inject at least at a latter stage of a compression stroke in at least in a low engine load and low engine speed condition, wherein a distance (L) from the tip end of the injector to an opposite end the combustion chamber is determined greater than a traveling distance (l1) of an injected fuel for a time period from a start of a fuel injection at the latter stage of the compression stroke to the ignition timing, wherein; an ignition plug (16) is arranged that an ignition gap (16a) is disposed within an injection area of the injector; and, wherein a distance (l2) from the tip end of the injector to the ignition gap is determined smaller than said traveling distance of the injected fuel. An ignitability and combustion stability can be improved to thereby improve a fuel consumption efficiency.
