Fuel injection device functional test starting method for use in internal combustion engine, involves conveying high pressure fluid to fluid cycle from inlet and outlet ports, where actuator varies fluid flow route and fluid pressure
摘要
<p>The method involves providing a nozzle (101) along the fluid cycle and receiving a nozzle needle (120) in the fluid cycle for opening and closing of the nozzle. An actuator varies the fluid flow route and fluid pressure to control opening and closing of the needle. High pressure fluid is conveyed to the fluid cycle from an inlet port (181). The high pressure fluid is conveyed to the fluid cycle from an outlet port (191). An independent claim is also included for a device for starting a functional test of an injection device.</p>
