🔍 Key Concepts

• cold starting of diesel engines and what factors make starting difficult in low temperatures • the effect of temperature on lubricating oil viscosity versus coolant/jacket water • how air intake heaters or glow plugs assist diesel combustion at start-up

💭 Think About

• Which part of the engine actually has the built‑in electric heater on many small diesels: the air intake, the coolant jacket, or the lube oil system? • When a diesel is hard to start in cold weather, what specifically needs to be warmed for fuel to ignite more easily in the cylinder? • Does increasing compression ratio require an electric device, or is it fixed by engine design (pistons, heads, etc.)?

✅ Before You Answer

• Verify which option refers to a property that is fixed by engine design and cannot be changed by simply switching on a heater. • Check which fluids (lube oil vs. jacket water) are normally heated by separate external heaters, not usually "built into" the small engine itself. • Focus on the answer that deals with air or combustion temperature at start‑up, since diesel ignition relies on hot compressed air rather than a spark.
