Maintain force is checked at the same time as fuel method stress. After the motor is switched off and the fuel pump stops operating, fuel system pressure will minimize slightly and afterwards maintain regular for at least five minutes.
The plunger is driven by a cam and tappet system at The underside. It reciprocates during the barrel. There are as quite a few plungers as the amount of cylinders within the engine. The plunger has an oblong vertical groove.
