Question 1 of 27070

Diesel engine starting difficulties due to cold intake air temperatures, can be overcome by using a/an __________.

🔍 Key Concepts

• diesel engine starting requirements • effect of cold temperatures on air, fuel, and lubricating oil • methods used to keep an engine warm when it is shut down

💭 Think About

• Think about what actually prevents ignition in a cold diesel cylinder: is it the fuel, the lube oil, or the temperature of the compressed air? • Which option would most directly warm the parts of the engine that surround the combustion space before you try to start it? • Ask yourself: which choice is commonly installed on standby or emergency diesel engines so they will start quickly even after sitting idle in a cold space?

✅ Before You Answer

• Verify which option would increase, not decrease, starting problems in cold weather (for example, heavier fuel or higher viscosity lube oil). • Consider which device or system is specifically intended to keep the engine at a suitable pre‑start temperature. • Eliminate any option that does not directly change the temperature of the engine block and intake air, but only changes fluid characteristics.
