🔍 Key Concepts

• Difference between cranking system (getting the engine to turn over) and the systems that keep it running • What a diesel engine does NOT use that a gasoline engine does • Role of the fuel system in maintaining continuous operation after start

đź’­ Think About

• If the engine is cranking normally, which systems are already working correctly? • For a diesel engine, what actually causes the fuel‑air mixture to ignite—do diesels rely on a traditional ignition system with spark plugs and coils? • Which system must keep supplying energy to the cylinders after cranking stops, or the engine will instantly stall?

âś… Before You Answer

• Confirm which choices (A–D) are involved only in getting the engine to turn vs. actually keeping it running • Recall that diesel engines depend on high compression and injected fuel, not spark ignition • Focus on which system, when interrupted, will cause an engine to start to fire then immediately die
