About This Quiz
Without an engine, your motor vehicle is pretty useless, isn't it?
We all know the anguish of when we get into our car and it simply won't start. And it could be a number of reasons that have caused this to happen. Why? Well, your car's engine is made up of thousands and thousands of parts, big and small, all working together to ensure the power generated by the engine is transferred into the energy that makes your vehicle move.
And just think of those first engine designers figuring out who to do this, often with so much trial and error. Those men were incredible but we should be eternally grateful to them. Those engines, just like modern ones need all its parts working in perfect harmony to make the engine run efficiently, because an engine that is not running as efficiently as it should is burning your money!
But now let's ask you a question: 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?
We want to test your knowledge with these 40 questions. Do you think you identify engine parts from just an image?
Can you name this belt that helps the engine run efficiently?
The timing belt is a toothed belt. It's usually made of reinforced rubber and it rides on the sprockets. It ensures that the pistons fire at the correct time, thus ensuring the engine runs as efficiently as possible.
Please can you tell us which engine part is shown in this image?
The carburetor controls the amount of air and gasoline entering the engine. For example, too much gasoline and the engine will run rich, wasting gas that it cannot burn, too little gasoline and it will run too lean.
Turn the key and this engine part swings into action. Can you name it?
When you turn the key of your car, the starter motor begins the combustion process by rotating the engine. Sometimes, when your car will not start, the starter motor is not operating properly and could be jammed.
Can you please name this engine part that moves in an up and down motion within a cylinder?
The piston fits snugly within the cylinder. It moves ups and down in the cylinder and is attached to a connecting rod. A piston will compress the fuel/air mixture in the cylinder and help cause combustion.
In this image we have a car part that moves coolant through the engine. Can you name it please?
Valve stem seal
This pump ensures that coolant which is kept in the radiator is moved through the coolant system on the car. It will only do so once the thermostat allows it to, and this depends on the temperature of the engine.
This part is essential to how your engine runs. It allows the fuel/air mixture into the cylinder of the engine where it will combust, causing the engine to run. It does this by evenly distributing the air/fuel mixture to the intake ports.
