Question 117Motor Plants - QMED
70% to passA normally operating diesel engine is shutdown by _______________.
Aoverspeeding the engine
Bsecuring the fuel supply
Cshutting off the air supply
Dsecuring the ignition system
AI Explanation
The correct answer is B) securing the fuel supply. A diesel engine operates by compressing air and then injecting fuel into the compressed air, which ignites the fuel and causes the engine to run. By securing the fuel supply, the engine is deprived of the necessary fuel, causing it to shut down. The other options, such as overspeeding the engine, shutting off the air supply, or securing the ignition system, would not directly result in the engine shutting down in a normal operating scenario.
