A) Compressing the air/fuel mixture until it ignites
B) Igniting the air/fuel mixture with the glow plugs

D) None of the above

Question

Quizplus · Accepted Answer

Diesel engines work by compressing air to increase its temperature, and then injecting fuel into the hot, pressurized air, causing ignition and creating power. This process is known as compression ignition, and is different from gasoline engines which use spark plugs to ignite the fuel/air mixture. Therefore, choice C - compressing the air and then injecting the fuel - is the correct answer.
