About This Quiz
Remove your car's engine and you aren't going anywhere!
With a faulty engine, a car is useless, unless you can convince people to push you everywhere. But let's be serious. Car engines consist of thousands of parts, all working in unison to transfer the power the engine makes into energy that makes your car move.
How did they manage to figure that all out over 100 years ago when the first engines were made? It's incredible, if you think about it.
But all those working parts not only need to work in perfect harmony to make an engine run. They must do so efficiently as well. An engine that isn't running properly is just going to cost you money somewhere down the line.
So just how much do you know about the internal combustion engine and car engines, in particular? Do you know your exhaust manifolds from your mufflers, your oil pump from your fuel pump or your spark plug from your glow plug?
You do? Then this is the quiz for you! Be warned, however, it's a tough one.
So take your time and let's see how well you do.
Good luck. You can do this!
Without this vital engine part, your car is not starting. What is it?
If your car's engine is turning over sluggishly when starting, or nothing happens except for a ticking sound, it's likely your battery is the problem. That is always the first place to check.
What part of the engine turns the motion of the pistons (linear) into a rotational motion?
Pistons move in a linear fashion, up and down, essentially. The crankshaft, which is connected to the transmission through a flywheel, turns that movement into a rotational movement, which is needed to move a vehicle forward (or backward, depending on the gear selected).
Name the engine part that ensures the air coming into the engine that forms part of the combustion process is clean and debris-free.
Mass airflow sensor
Air intake manifold
The air entering your car's engine needs to be clean. This is the air filter's job. Depending on the roads you drive on, it should be replaced every 15,000 to 30,000 miles, more often if you drive on dusty, unpaved roads.
Open and close to let the gas/air mixture into the cylinder, then seal to allow combustion
It's all about timing! Valves must open to let the gas/air mixture into the cylinder and then close to allow combustion to happen. Finally, they open to release the gases that are left over after the combustion process.
What part of the vehicle removes the gases produced by the combustion of the gas/air mixture?
The by-product of the combustion of the gas/air mixture during combustion is a number of gases. These need to be removed from the engine through the exhaust system, starting with the exhaust manifold which collects the gases from the various cylinders then sends them down the exhaust system and out the tailpipe.
