Question 151Motor Plants - Assistant Engineer

The correct answer is D. The injector rack of the diesel engine shown in the illustration is indicated by the component labeled "G". The injector rack is a critical component in a diesel engine, as it is responsible for delivering the fuel to the engine's cylinders. The labeling in the provided illustration clearly identifies the injector rack as component "G", which makes this the correct answer. The other answer choices are incorrect because they label different components in the engine, such as the fuel pump ("B"), the engine block ("E"), and the fuel filter ("F"), which are not the injector rack.
