Structural principle and working mode of EFI motorcycle fuel injectors The fuel injectors in the motorcycle EFI system is one of the most important actuators. In fact, the main carrier of the word "electrospray" is the injector. Today we will introduce the structural principle and working method of this component. 1. What structure of fuel injectors is used for EFI motorcycles? The function of the injector is to rapidly and precisely spray a well-sprayed gasoline to the engine intake port at regular intervals (Fig. 14). The injector used in EFI motorcycles is a shaft-type electromagnetic injector (Fig. 15). It consists of an injector housing, a nozzle, a needle valve and an armature ring that fits over the needle valve. It is a machining accuracy. Very high precision devices play a key role in the actuators of fuel injection systems. The amount of fuel injected by the injector depends on three factors: 1 The size of the cross-sectional area of ??the fuel inject...

How to adjust check the timing of the mechanical fuel pump To be able to check and modify the fuel supply advance angle, when production the diesel engine, the maker generally marks the timing at the corresponding position of the diesel engine and the Mechanical fuel pump :  It refers to the fixed time range on the Mechanical gasoline pump coupling (or automated advancer) and the essential oil pump bearing cover. As long as both lining lines are aligned, it really is sure to be Enough time when the Mechanical fuel pump starts to provide oil to the first cylinder;  The average person identifies the engraved series on leading end of the crankshaft. And a pointer on the front cover of your body; For the multi-cylinder diesel engine,   the unloading advance placement of the oil supply can be confirmed. The meshing mark of the Mechanical gas pump and the corresponding transmission gear may be aligned following the diesel engine is definitely overhauled,  Pe...

7 reasons for direct-injection fuel pump assembly fail Don’t be frightened by direct fuel injection diagnostics. Theoretically, these systems are powered by the same concepts as port gas injection, but immediate injection can inject more exact amounts of fuel in to the combustion chamber therefore the engine can operate leaner and better. The key to direct injection is a fuel pump assembly. This pump is certainly precision-machined to generate energy pressure to the rail up to 2, these gasoline pump assemblys are typically powered by a camshaft and so are able to differ their displacement and result to match the requirements of the engine. fuel pump assembly s may malfunction and/or Invalid because of numerous factors. Diagnosing problems with these pumps isn’t as well difficult in the event that you know what to consider. 1. Lack of Maintenance The primary destroyer of fuel pump assemblys is too little oil changes. Put on between your camshaft lobes and the high-pressure pump ...
