The Mechanics Of Car Engine Operation

The video explains how a car engine works, focusing on the four-stroke cycle: intake, compression, power, and exhaust. It covers the engine's main components, including pistons, crankshaft, camshaft, and the firing order. The video also details supporting systems like air intake, fuel delivery, cooling, electrical, oil, and exhaust systems, highlighting their roles in engine operation.

What is the primary function of a piston in a car engine?

• To ignite the fuel-air mixture

• To compress the air-fuel mixture

• To open and close the valves

• To transfer power to the crankshaft

How many strokes are there in a typical car engine cycle?

• Two

• Three

• Four

• Five

What is the firing order for the engine discussed in the video?

• 1-2-3-4

• 4-3-2-1

• 2-3-1-4

• 1-3-4-2

What does RPM stand for in the context of car engines?

• Revolutions Per Minute

• Rotations Per Minute

• Rounds Per Minute

• Rates Per Minute

Where does the air mix with fuel before entering the cylinders?

• In the exhaust manifold

• In the intake manifold

• In the fuel tank

• In the oil pan

What is the purpose of antifreeze in a car engine?

• To lubricate engine parts

• To clean the engine

• To prevent the engine from overheating

• To keep the engine from freezing in cold weather

What component delivers the electrical spark to ignite the fuel-air mixture?

• Alternator

• Battery

• Fuel injector

• Spark plug

What is the role of motor oil in an engine?

• To increase engine speed

• To lubricate and clean engine parts

• To cool the engine

• To ignite the fuel

What does the exhaust manifold do?

• Cools the engine

• Collects exhaust gases from cylinders

• Mixes air and fuel

• Lubricates engine parts

What is the function of the catalytic converter in the exhaust system?

• To capture toxic chemicals in exhaust gases

• To reduce exhaust noise

• To improve fuel efficiency

• To increase engine power
