DIRECT-INJECTION INTERNAL COMBUSTION ENGINE WITH OUTWARDLY OPENING INJECTION NOZZLE, AND METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF SAID TYPE
摘要:
A direct-injection engine having a cylinder in which a combustion chamber is jointly formed by a piston crown of a piston, which is movable along the longitudinal axis of the cylinder, and a cylinder head, and an injection nozzle, which is arranged in the cylinder head on the opposite side of the piston crown eccentrically, spaced apart from the longitudinal axis of the cylinder, for the direct injection of fuel, which injection nozzle has a nozzle needle movable in a nozzle body, wherein the needle in the open position of the nozzle is moved into the combustion chamber, opening up an annular gap arranged between the nozzle body and needle.
