    • In a direct fuel injection diesel engine equipped with a pentroof-shaped piston, a collision angle (α) at which fuel injected in a direction in which the height of the top face of a piston (13) is high collides with a cavity (25) is set larger than a collision angle (β) at which fuel injected in a direction in which the height of the top face of the piston (13) is low collides with the cavity (25). By so doing, in a direction in which the height of the top face is high fuel that has collided with the cavity (25) easily rebounds upward, thus achieving effective combustion by mixing with a large amount of air present in the vicinity of the opening of the cavity (25) where the height is high, and in a direction in which the height of the top face is low it is difficult for fuel that has collided with the cavity (25) to rebound upward, thus achieving effective combustion by suppressing the flowing out of fuel or flame from the opening of the cavity (25) where the height is low, thereby appropriately mixing fuel and air in all directions in the circumferential direction of the cavity and making it possible to improve the engine output and reduce harmful exhaust substances.
    • 在配备有五角柱形活塞的直接燃料喷射柴油发动机中,在活塞(13)的顶面高度与空腔(25)碰撞的方向上喷射的燃料的碰撞角(α) )被设定为大于在活塞(13)的顶面的高度低的方向上喷射的燃料与空腔(25)碰撞的碰撞角(& bgr)。 通过这样做,在顶面的高度与空腔(25)碰撞的高度高的方向上容易地向上弹回,从而通过与存在于​​开口附近的大量空气混合而实现有效的燃烧 在高度高的空腔(25)中,并且在顶面高度低的方向上,与空腔(25)碰撞的燃料难以向上回弹,从而通过抑制来实现有效的燃烧 从高度低的空腔(25)的开口流出燃料或火焰,从而在空腔的圆周方向上适当地混合燃料和空气在各个方向上,并且可以改善发动机的输出并减少有害的 排气物质。
