Question 214Motor Plants - 1st Asst/Chief70% to pass
Which of the following is one of the ways to prevent a scavenging fire on a slow speed diesel engine?
AI Explanation
The correct answer is B) Keep the scavenging space clean and free of oil.
Scavenging fires on slow speed diesel engines are typically caused by the ignition of oil or combustible materials in the scavenging space. Keeping this space clean and free of oil buildup helps prevent the accumulation of flammable materials that could ignite and cause a fire.
The other options are not the primary ways to prevent scavenging fires. Preventing air entry (A) may help, but it does not directly address the root cause of the fire hazard. Shutting down the engine (C) is a reactive measure, not a preventative one. Monitoring bearing temperatures (D) can help detect issues, but does not directly prevent scavenging fires.
