Title: Fuel injection device for engine
Inventor: YAMADA TOMOHIDE
IPC: F02M61/10
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To increase the reduced amount of the pressure loss within a fuel injection valve and to realize high pressure injection by providing a fuel revolving means on an upstream side fuel passage on an upstream side of a fuel reservoir within a nozzle body of the fuel injection valve or a downstream side fuel passage between the fuel reservoir and a nozzle hole. SOLUTION: Fuel which is forcibly fed by a plunger within a unit injector at the time of operating a fuel injection device leads to a fuel reservoir 20 via a fuel passage 19 within a nozzle body 18. At the time of fuel injection, fuel within the fuel reservoir 20 forms a spiral flow along a spiral groove 26 of a needle valve passage 17a, flows into a suck part 22. A directional change of the flow in flowing into the suck part 22 is reduced by this spiral flow, a directional change in flowing from a sheet part 21 to a nozzle hole 23 via the suck part 22 is reduced by the formation of a spiral groove 26 and thereby pressure loss is reduced. Subsequently, fuel is injected from the nozzle hole 23 when a needle valve 17 is pushed up.
