摘要： With regard to a direct injection diesel engine comprising a piston 11, which has an upper recess constituting a cavity 21, and a fuel injection nozzle 12 injecting fuel into the cavity 12 of the piston, nozzle holes 32, which have at least a plurality of intersecting points between an axis of the fuel injection nozzle 12 and opening direction of the nozzle holes 32, are regarded as a pair, and a plurality of the pairs of the nozzle holes are provided in the fuel injection nozzle 12. An opening of a combustion chamber of the piston 11 is a polygon which has five or more corners. Accordingly, with regard to the diesel engine, engine output is improved, and noise and hydrocarbon in discharged gas are reduced.

摘要： An engine includes an angular velocity detecting means 10 for detecting a rotation angular velocity of a crankshaft 11 of the engine, a torque generated by the engine detecting means for detecting a variability of the angular velocity amplitude obtained by the angular velocity detecting means 10 as the variability of the torque generated by the engine. The engine compensates a fuel injection quantity by comparing the angular velocity amplitude detected by the angular velocity detecting means with the adequate angular velocity amplitude.
