Quiz Answer Key and Fun Facts

1. Current gasoline powered cars have two-stroke engines.

Answer: False

Gas engines have 4-cycle engines (intake, compression, power and exhaust).

2. Anti-freeze cools your engine.

Answer: True

Besides preventing your engine from freezing when ambient temperatures reach the freezing point (32F or 0C), it serves as a coolant to keep your engine within operating parameters.

3. The more common U.S name for the "differential" is the....?

Answer: Rear End

"Differential" refers to the fact that the rear allows the driving force to be distributed equally to both axles while permitting one to revolve faster than the other, hence, "differential".

4. Which of the following is NOT a part of a "disc brake" system?

Answer: Wheel cylinder

Wheel cylinders are part of a "drum-brake" system.

5. Your car's battery has a "CCA" rating. "CCA" means...?

Answer: Cold Cranking Amperage

This rating determines the stored power of your battery in cold conditions.

6. Diesel engines have spark plugs.

Answer: False

Diesel engines are fired by the heat of compression, thereby requiring no spark plugs. (Though some diesels have glow plugs, they are not the same as spark plugs).

7. A "check engine" light on your dashboard normally refers to a fault being reported by your car's _____ system.

Answer: Computer

This light means that your car's computer has detected a fault in one of the systems that are controlled by the ECM or electronic control module which is your car's computer brain.

8. When referring to ignition timing, "TDC" means what....?

Answer: Top dead center

It means when the piston has reached it's upward-most rotation (not going up and not going down). Most ignition systems are timed by the #1 piston, but not all. (International Harvester 345 engines are timed to #8).

9. If your car has "EFI", you have a computer-controlled carburetor.

Answer: False

"EFI" refers to "electronic fuel injection", which means there are fuel injectors and not a carburetor.

10. The "thermostat" in your car's cooling system controls the temperature of your air conditioning.

Answer: False

The thermostat controls the temperature of your engine's coolant.

11. A timing belt and a timing chain serve the same function.

Answer: True

They both "time" the crankshaft with the camshaft(s).

12. Which one of these automobiles was NOT produced by "General Motors"?

Answer: Mercury

Mercury was a Ford product.

13. Where are "U-joints" located?

Answer: Driveshaft

"U" meaning "universal" refers to the ability to rotate in all directional angles without losing RPM's.

14. Turn signals blink with the help of a form of circuit breaker.

Answer: True

They blink with the help of a flasher, which is a self-resetting circuit breaker. It works by heating up and cooling very quickly, thus breaking and then connecting a circuit repeatedly.

15. In German, what does "BMW" stand for?

Answer: Bayerische Motoren Werke

The English translation would be "Bavarian Motor Works". Thank you for playing my quiz!
