About This Quiz
Your car engine is made up of many, many parts. If one fails, chances are that your car is not moving!
So how does it all work? Well, the engine provides the power. This is fed through the transmission, either manual or automatic, to the differential which, in turn, will turn the wheels of the car. Sounds simple enough but it isn't, really. How those engineers worked this all out all those years ago still boggles the mind, don't you think?
All those parts have to work in perfect harmony. Pistons moving, valves opening at the right time, spark plugs firing at the right instance, gasses moved out of the engine. One little problem, and the engine might still run, but not efficiently.
So let's get onto the task at hand. In this quiz, you will be given a description of a car part and a brief idea of what it does in the engine. From that, you will have to identify it from four choices. Seems simple enough, right? Well, some are pretty simple but what about the inner workings? Do you know all the parts that help make an engine run or the supporting parts, without which the engine wouldn't even start?
