Fuel injection valve for internal combustion engine |
摘要 |
A fuel injection valve for an engine includes a nozzle located in the vicinity of a cylinder head of the engine. The nozzle has nozzle holes each being opposed to an in-cylinder space defined in a cylinder of the engine. Each nozzle hole has an imaginary injection line that extends from each nozzle hole into the in-cylinder space. The imaginary injection line is directed toward either an upper surface of the piston or the wall surface of the cylinder. The in-cylinder space includes divided spaces each including the nozzle and at least one imaginary injection line. The divided spaces include a piston-side divided space and a head-side divided space. The head-side divided space contains fuel and air mixed at an air fuel ratio that is greater than an air fuel ratio of fuel and air in the piston-side divided space.
