定めた直噴式デイーゼル機関の燃焼室。 A direct injection diesel engine, wherein a first concave fuel reflecting surface is formed on the bottom wall of the cavity, and fuel injected from a fuel injection valve toward the first concave fuel reflecting surface is reflected at the first concave fuel reflecting surface. In the engine, a second concave fuel reflecting surface having an arcuate cross section is formed on the inner circumferential wall of the cavity, and fuel is injected from the fuel injector with the second concave fuel reflecting surface facing, and the second concave fuel reflecting surface is formed on the inner peripheral wall of the cavity. A combustion chamber of a direct injection diesel engine, in which the formation position and cross-sectional shape of a surface are determined such that the injected fuel reflected by the second concave fuel reflecting surface sequentially moves from the cavity periphery to the cavity center as the piston rises.
