About This Quiz
Are you one of those people who like to know what’s under their car’s hood? Have you ever opened the hood and wondered what exactly is in there and how it all works?
When buying a new car, it can be more than useful to understand what sort of an engine that car is equipped with, how it works and which parts it includes. We all know that the very purpose of a gasoline engine is to convert fuel into motion so that you can move your car. Burning the gasoline inside an engine is the most efficient way of creating motion from gasoline today, which means that a car engine is, in fact, an internal combustion engine. But, how much more do you know?
For many people, a car engine may look like a big, hot, confusing structure built out of various tubes and wires. For others, however, it’s very clear what each of those tubes and wires is and how each little system works. To which group do you belong? Can you name a car engine part just by looking at a photo of it? We’ve thrown in some hints to help you out, so feel free to start that engine and ace this quiz!

What do you call this snail-shaped part?
A turbocharger’s role is to force extra compressed air into the combustion chamber and thus increase an internal combustion engine’s efficiency and power output.
You’ll probably know what this engine part is called. Can you name it?
A throttle is a valve that controls the volume of vaporized fuel delivered to the cylinders of an internal combustion engine.
