行なうようにした直噴式デイーゼル機関。 In a direct injection diesel engine equipped with a glow plug, a first fuel reflecting surface and a second fuel reflecting surface are formed on the inner peripheral wall surface of the cavity, and fuel is injected from a fuel injection valve toward these fuel reflecting surfaces, The first
The direction of the fuel reflecting surface is set so that the injected fuel reflected from the first fuel reflecting surface collides with the glow plug, and the direction of the second fuel reflecting surface is set so that the injected fuel reflected from the second fuel reflecting surface collides with the glow plug below. The injected fuel is directed into the cavity, and when the engine is started, fuel is injected at a time when the injected fuel collides with at least the first fuel reflecting surface, and after warm-up is completed, the injected fuel is injected at a time when the injected fuel collides only with the second fuel reflecting surface. A direct injection diesel engine that uses fuel injection.
