What is a Piston in a Car?

Pistons are a critical part of any internal combustion engine. The piston is vital in converting fuel to energy, allowing the vehicle to drive forward. Pistons have a thick metal plate that compresses gas inside the cylinders. The plate is the same size as the cylinders, so no fuel or air can escape around the sides. 

It starts at the top of the cylinder as the valves are opened to fill the cylinder with fuel and air. The piston is then forced downwards to compress this mixture of fuel and air. This compression creates a more powerful explosion when it is ignited by the spark plug. The force from this explosion moves the piston up, and the exhaust valve opens to allow the burnt fuel and fumes to leave the cylinder. Thus completing the cycle. 

This movement of the piston turns the crankshaft at very high speeds.

What happens when your Car Pistons Fail?

If one or more car piston fails, you'll notice a severe drop in power from your engine. In some severe cases, a cracked or damaged piston will seriously diminish the combustion process in the engine, causing it to cut out completely.
