A study by ethical car recycling company Scrap Car Network found that we can’t identify many of the really important parts of our car engines.
This is perhaps surprising, as mechanically, very little has changed in the past thirty years or so.
Engines are Pretty Much the Same as They’ve Always Been
Modern cars use the same type of combustion engine that’s always been used. This type of engine mixes fuel with air which is then inducted into several cylinders. A series of pistons compress the mixture, and a spark then ignites it. The combustion pushes a set of pistons that move up and down. A crankshaft then translates this motion into linear movement, which makes the car move.
