🔍 Key Concepts

• Purpose of a crankcase on a diesel engine • Why gases and vapors might build up in an engine crankcase • Safety reasons for removing fumes from enclosed engine spaces

💭 Think About

• Ask yourself what could happen inside the crankcase if oil mist and fuel vapors were allowed to build up with no way out. • Think about which option is focused on safety rather than performance or convenience. • Consider which answer choice matches a ventilation system’s normal job on any machinery: what does ventilation usually try to control or remove?

✅ Before You Answer

• Identify which choice deals with removing or controlling gases or vapors rather than changing oil properties. • Eliminate options that talk about improving performance (starting, cooling) instead of addressing a hazard. • Recall that crankcase explosions are a known risk on large engines; which option is most directly related to preventing that hazard?
