摘要： Improvement of combustion stability in retard ignition at the time of starting in a cold state, high output in a full throttle condition, reduction of smoke, and prevention of wear of the cylinder liner caused by oil dilution, are to be attained. In connection with the flow of fuel into each hole and a fuel inflow angle which is determined by the axis of each hole formed in a plate, the fuel inflow angle of an hole directed to a spark plug is set large to reduce an effective flow path area, thereby making the amount of fuel in the hole smaller than in other holes. A shallow cavity is formed in a piston crown face and a small prominence confronting fuel sprays is formed within the cavity.

摘要： It is necessary to attain the combustion stability when performing ignition retarding in order to reduce exhaust gas and raise the exhaust gas temperature under a cold start condition, as well as soot reduction under a fully open throttle valve condition.An injector according to the present invention comprises: a plurality of fuel passages having an axis line inclined with respect to a valve operation axis line at a nozzle end; wherein inclined axis lines of at least three of the fuel passages have a spreading angle, none of them intersecting with each other, and three injection points are formed in a plane perpendicular to a valve operation axis line to form a triangle; and wherein at least one center-oriented fuel passage having an injection point around the center of the triangle is provided.
