Q

Diesel engine electric starting motors generally require heavier duty motors and operate at higher voltages than comparable starting motors for gasoline engines due to __________.

🔍 Key Concepts

• Diesel vs. gasoline compression ratios and what that means for how hard the starter has to work • How starting torque and current draw relate to motor size and voltage • The effect of engine speed at start-up versus the resistance inside the cylinders

💭 Think About

• When cranking a cold diesel, what internal engine force is the starter motor working hardest to overcome? • Would a diesel need to spin faster than a gasoline engine to start, or does some other characteristic make it harder to turn? • Which listed factor would most directly increase the torque required from the starter motor?

✅ Before You Answer

• Identify which choice most directly increases resistance to turning the crankshaft during starting • Ask which factor would force the starter to draw more current and need heavier construction • Eliminate options that mainly affect engine behavior after starting, not during the initial cranking
