摘要： In a direct fuel-injection engine equipped with a pentroof-shaped piston, cross-sectional shapes containing a piston central axis (Lp) of a cavity recessed in a central part of the piston having a top face with the height varying in the circumferential direction are set so as to be basically identical at each position in the circumferential direction (see broken line). Since the sizes of the cross-sectional shapes of the cavity thereby become different in a region further on the piston central axis (Lp) side than intersection points (e1, d1) in the vicinity of a fuel injection point (Oinj), in order to compensate for this, by correcting in a cross section that is away from the piston pin direction the cross-sectional shape of the broken line into the cross-sectional shape of a solid line so that it enlarges, the size of the cross-sectional shape at each position of the circumferential direction of the cavity is thereby made more uniform, thus making the conditions in which fuel and air are mixed uniform and improving the engine output and reducing harmful exhaust materials.

摘要： A direct fuel-injection engine includes a piston, a cavity recessed in a central part of a top face of the piston, and a fuel injector. At a main injection collision point of a fuel-injection axis when main injection is performed while the piston is near top dead center, a main injection collision angle formed between its tangent and the fuel-injection axis is set at an obtuse angle. Fuel colliding with the main injection collision point is deflected towards a cavity open end side. At a secondary injection collision point of the fuel-injection axis when performing secondary injection with the piston is further from top dead center, a secondary injection collision angle formed between its tangent and the fuel-injection axis is set at one of a right angle and an acute angle. Fuel colliding with the secondary injection collision point is deflected primarily in the circumferential direction of the cavity.
