If we should go further into detail about how a car engine works, then we must say that at the beginning of the cycle, the piston starts at the top, once the intake valve opens, the piston moves down, letting the engine take in a cylinder full of air into which is injected a drop of petrol. The piston then moves back up to compress the air with the drop of petrol, the compression will make the explosion which is about to occur all the more powerful. When the piston reaches its limit, the spark plug emits a spark which ignites the petrol, causing an explosion thus driving the piston back down. When the piston reaches its bottom limit, the exhaust valve opens and the exhaust leaves the cylinder. And this cycle is repeated over and over again. The cylinder is a very important part for the internal combustion engine. Usually, cars have four, six or eight cylinders.
So, if you have not opened the hood of your own car yet and wondered how a car engine works, here you might understand the way an internal combustion engine functions in making your car take the required actions. At a first glance, your car engine might look as a big confusion of metal, tubes and wires, but this perfect mechanism is the one which enables your car to function the way it should be. Although a lot of men are passionate about cars few actually know how an engine works. Automobile constructors always try to improve the engine in order to increase a car’s performance. When reading a we are not always able to understand how the upgrades improve the performance. We hope that the information featured in this articles will not only help you understand how a car works but it will also help you compare different cars.
