[002] In the conventional approach, the injection pump drive indirectly from the crank shaft to deliver the right quantity of fuel in to the combustion chamber via fuel injector device for better combustion. It also opts for gear train arrangement to drive the fuel injection pump. This leads to the increases overall weight of the engine. Hence additional space required to fit the fuel injection pump in gear train arrangement system drive of the engine. Although their complexity makes it complicated to replace individual parts.
[003] The existing solution for transferring the power from the cranks sprocket to the cam sprocket through chain drives mechanism. The fuel injection pump need to be mounted and bolted to the cam sprocket and fuel injection pump shaft has cam, projected on it, providing driving mechanism to the cam roller of fuel injection pump system, creates more deflection in the main shaft drive.
