Car Smarts: Engine Performance
Whether racecar driver or casual commuter, odds are you're going to be concerned about engine performance at some point in your driving career. But can you even tell the difference between a camshaft and a stick shift? You will once you take the engine performance quiz.
1) Bolt-on accessories that make it easier for your engine to push exhaust gases out of the cylinders are called:
- Headers
- Footers
- Mufflers
2) If you're using an exhaust header with a four-cylinder engine, how many exhaust pipes will you have?
- One
- Two
- Four
3) Why do properly inflated tires improve fuel efficiency?
- They decrease the force of friction
- They decrease the force of Gravity
- They’re lighter
4) During the exhaust stroke, many engines lose power through:
- Exhaust manifolds
- Back pressure
- Exhaust headers
5)Nitrous oxide improves engine performance by providing more what?
- Nitrogen
- Oxygen
- Hydrogen
6) What other benefits does nitrous oxide provide?
- A cleaner-burning fuel
- A cooling effect
- A quieter performance
7) Why do cars normally carry only a few minutes worth of nitrous oxide?
- It’s difficult to find
- It's expensive
- It's fairly bulky
8) How much faster can the turbine in a turbocharger spin when compared to a regular car engine?
- 10 times faster
- 20 times faster
- 30 times faster
9) How many valves per cylinder do dual overhead camshafts typically have?
- Two
- Four
- Six or more
10) Three fundamental causes can keep your engine from running. Which of the following is not one of them?
- Bad fuel
