Car engine pistons are an essential component of an internal combustion engine. They play a crucial role in converting the energy generated by the burning of fuel into mechanical energy, which powers the vehicle. Pistons are cylindrical in shape and made of high-strength materials such as aluminium or steel. They move up and down inside the engine cylinder, allowing the fuel-air mixture to be compressed and ignited. Without properly functioning pistons, an engine would not be able to operate efficiently, resulting in decreased performance and potential engine failure.

Frequently Asked Questions (FAQs)
1. How much does it cost to replace pistons in a car?
The average auto mechanic charges between $100 to $200 per hour to replace a blown piston. A new piston ring costs around $100, so you'll have to add that to the cost of how long it takes your mechanic to complete the job.
2. How do pistons in a car work?
In a spark ignition engine, the fuel is mixed with air and then inducted into the cylinder during the intake process. After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke.
3. How many pistons are on a car?
The majority of cars have four, six, or eight of them. Inside each cylinder is a piston that slides up and down, and as it does so, it turns a crankshaft that's attached to a gearbox, which in turn powers the car's wheels.
