Question 64Motor Plants - Assistant Engineer
70% to passLoad control on a diesel engine is accomplished by_______________.
Aregulating the speed of the turbocharger
Bregulating the amount of fuel admitted to the engine
Cregulating the speed of the fuel oil transfer pump
Dchanging engine timing
AI Explanation
The correct answer is B) regulating the amount of fuel admitted to the engine. The load control on a diesel engine is primarily accomplished by regulating the amount of fuel admitted to the engine. This is because the output power of a diesel engine is directly proportional to the amount of fuel injected into the engine. By adjusting the fuel delivery, the engine's load can be effectively controlled. The other options are not the primary means of load control on a diesel engine. Regulating the speed of the turbocharger (A) or the fuel oil transfer pump (C) are not the main methods of load control. Changing engine timing (D) is more related to engine efficiency and emissions, not direct load control.
