This diagram shows the different parts of the injector pump and how they work together. The injector pump is responsible for delivering fuel to the engine's cylinders. It does this by drawing fuel from the fuel tank and then pressurizing it and injecting it into the cylinders at the correct time.
The injector pump is driven by the engine's camshaft. The camshaft rotates a series of plungers, which in turn draw fuel into the pump and then pressurize it. The plungers are actuated by a series of tappets, which are controlled by the engine's valves.
The injector pump also contains a governor, which controls the amount of fuel that is delivered to the engine. The governor is actuated by a flyweight, which is driven by the engine's crankshaft. As the engine speed increases, the flyweight moves outward and causes the governor to reduce the amount of fuel that is delivered to the engine. This helps to keep the engine from overspeeding.
The injector pump is a critical component of the engine, and it is important to keep it in good working order. If the injector pump fails, the engine will not be able to run properly.
