About This Quiz

Do you have gears in your head instead of the traditional gray matter? Are you always thinking about how engines run, learning about the different designs out there? 

Engines can be incredibly complex. Of course, early designs were relatively simple, usually only having a few dozen parts or so. Thanks to the desire for smoother operation, more power, less noise, greater reliability, increased longevity, lowered emissions, improved fuel efficiency and more, the design of modern engines has evolved into something far more complex. Your engine might contain hundreds of parts, which all serve a very precise purpose. 

It's amazing to think how quickly the different actions happen inside your engine, all without problems, at least for the most part. To regard engines as anything other than mechanical miracles is to not appreciate them nearly enough. Just let something obscure go wrong with your engine, especially something that leaves you stranded on the side of the road, and you'll come to a whole new appreciation for the complexity of these machines.

Just how much do you know about the different components in various engines? Could you guess what a component is with a short hint? Try out your skills now by taking this quiz! 

1.0 of 35
This part ignites the fuel in the cylinder.
2.0 of 35
You must remove this part to put more oil in the engine.
3.0 of 35
This part literally attaches the engine to the car's frame.
4.0 of 35
This is where the combustion process takes place.
5.0 of 35
As the pistons move up and down, they make this part rotate.
6.0 of 35
This part allows the fuel and air mixture to flow into the cylinder.
7.0 of 35
This part is attached to the piston and the crankshaft.
8.0 of 35
All the air/fuel mix and exhaust gases flow through this part.
9.0 of 35
This part will detect preignition and detonation.
10.0 of 35
This part is where the engine oil naturally flows and gathers.
11.0 of 35
This part is shaped like a can and it moves up and down.
12.0 of 35
This transports the exhaust gases to the catalytic converter.
13.0 of 35
This part measures how much unburned oxygen is in the exhaust gases.
14.0 of 35
This part measures the precise amount of gas that should go into each cylinder.
15.0 of 35
This part keeps the valve shut tight, allowing no gases to escape until the valve opens again.
16.0 of 35
This part keeps the camshafts spinning at the right speed.
17.0 of 35
This keeps the entire engine from getting too hot.
18.0 of 35
This forms a tight seal between the cylinder head and the engine block.
19.0 of 35
This carries electricity to the spark plugs
20.0 of 35
This regulates when the exhaust gases leave the cylinder.
21.0 of 35
This part has lobes that control when valves open, how much and for how long.
22.0 of 35
This part makes a tight seal between the intake manifold and cylinder head.
23.0 of 35
This part is always spinning behind the engine.
24.0 of 35
In an overhead valve engine, this part moves the valves.
25.0 of 35
This part measures the temperature of the air coming through the air intake.
26.0 of 35
This holds the connecting rod and piston together.
27.0 of 35
This part can trigger a warning if your oil level is too low.
28.0 of 35
This is the final part to transport fuel to the injectors.
29.0 of 35
This part protects the timing belt from interference and the elements.
30.0 of 35
The timing belt connects to this part, which also connects to the camshaft.
31.0 of 35
You use this to check the oil level in the engine.
32.0 of 35
This part maintains proper valve clearance with the rocker.
33.0 of 35
This device sends oil to the various parts of the engine.
34.0 of 35
This part keeps exhaust gases flowing into the manifold.
35.0 of 35
In some overhead cam engines, this part interacts with the camshaft and opens the valve.
