How your car works, the basics.

5 Dec , 2016  

For many motorists, knowing how their car works isn’t essential. But then when something goes wrong, you might well find yourself wishing you knew more.

The fact is, the more you know about the car you drive, the better. With that in mind, let’s take a look at some of the basic mechanics of a standard car. You never know, it could help you fix a problem that might arise.

The Engine

Let’s start, first of all, with the heart of the car – the engine.

Knowing how this functions is a good idea, as it’s obviously a hugely important part of the vehicle. In general, engines are internal combustion machines which create the energy needed to drive the vehicle forward.

The whole chain of events is caused by a single spark, which ignites petrol vapour and compressed air inside a sealed cylinder. This then burns rapidly, and expands as it does so. This creates the energy to move the pistons up and down, which is turned by the crankshaft into a circular motion of energy. Powering the car.

If something is majorly wrong with the engine its pretty obvious, and you wont be getting anywhere fast…or at all.
Apart from that, however, also be on the lookout for any strange smells or noises from the hood of the car.

The Cooling System

The engine is a good starting place, but there is much more to your car than that. If you want to be a real car pro, it is a good idea to learn as much as possible about how a car works.

Next, let’s take a look at the cooling system inside your average car. Problems with the cooling system could cause many issues, so this is important to know.

There are actually two types of cooling system: liquid cooled and air cooled. Most modern vehicles now use liquid cooled, so we will focus on that.

The system sends liquid coolant through a series of passages in the engine block and heads. As it does so, it picks up heat from the engine. It then travels to the radiator, and is cooled by the air entering the grills at the front of the car.

An overheating vehicle is something which could potentially be very dangerous, so understanding this is hugely important.




The Clutch

The clutch is the first stage in the transmissions process. It transmits engine power to the gearbox, allowing the transmission to be interrupted.

This is achieved by using friction or a cable. A pressure plate on the flywheel exerts a force on the driven plate.

When the clutch is released, the opposite happens. When there is a problem with the clutch, it is likely that you will know it before you even set off.

This is something you might want a professional to look at for you as it’s quite an involved proceedure if anything goes wrong with it.
