About This Quiz

Engines are some of the most technologically interesting machines on the planet. They’re the result of years of invention, innovation and mastery. You ride in your car every day without realizing the amazing process that’s happening right under the hood.

Camshafts, intake valves, combustion chambers, valve springs, cylinder heads — your internal combustion engine is the heart of your vehicle, but all the parts are an intricate system of veins and arteries keeping the whole thing moving. Whether you need to make sure your knowledge is really up to snuff, or you’re just a little bored at work and mechanically minded, this quiz is going to give you the ride of your life.

Do cars have more than one piston and valve? Does increasing the number of pistons give you more power? Hey, you’ve got an inquisitive mind, a desire to understand your vehicle and an honest-to-goodness need for speed. 

And just because you read this far, here’s a fun fact: A cannon is really just a simple type of combustion engine. The cannonball is packed into the cannon, along with gunpowder. When you light the gunpowder, it creates gas and pressure, so the cannonball flies. See how fascinating this stuff is? Let’s do this!
