    摘要: A quadrangular combustion cavity V in the crown of a diesel engine piston is offset from the center thereof, and the position of the fuel injector nozzle is also offset relative to the center of the cavity to accomodate enlarged intake and exhaust valves. The rotational orientation of the nozzle and cavity are geometrically determined such that:A. the fuel distances J.sub.1, J.sub.2 and J.sub.3, J.sub.4 are equal,B. the angles between a line A connecting the geometric center C.sub.1 of the cavity and the center C.sub.2 of the nozzle, and fuel jet directions J.sub.1 and J.sub.2 are equal, as are the angles between line A and fuel jet directions J.sub.3 and J.sub.4, andC. the difference between the maximum jet distance J.sub.1 and the minimum jet distance J.sub.3 is minimizedThe distances from the four fuel impingement points Z.sub.1 - Z.sub.4 on the side walls of the cavity to the respective corners of the cavity are also equal.
