FUEL INJECTION VALVE FOR DIESEL ENGINE
PURPOSE:To prolong fuel injection time without reducing injection pressure particularly in low revolution and low loading state of an engine, by jetting-out fuel in two stages. CONSTITUTION:The first needle 8 and the second needle 9 are inserted into a nozzle body 1. The second needle 9 is inserted...

| description | PURPOSE:To prolong fuel injection time without reducing injection pressure particularly in low revolution and low loading state of an engine, by jetting-out fuel in two stages. CONSTITUTION:The first needle 8 and the second needle 9 are inserted into a nozzle body 1. The second needle 9 is inserted in movable ways into the first needle 8. Since the spring force of the second pressure spring 20 is made relatively smaller than the spring force of the first pressure spring 14, the second needle 9 lifts earlier when an equal fuel pressure is applied onto the first needle 8 and the second needle 9. Therefore, fuel is jetted-out from the second injection hole 18, passing through the first injection hole 6, and then the first needle 8 lifts, and all the necessary amount of fuel is jetted-out from the first injection hole 6. |
