How does our car engine work?

Engine: “The purpose of a gasoline car engine is to convert gasoline into motion so that your car can move. Currently, the easiest way to create motion from gasoline is to burn the gasoline inside an engine. Therefore, a car engine is an internal combustion engine”

There are hundreds of gasoline cars on the market today and they all work pretty much the same, some might have extra mods added to the engine which increases the performance on the vehicle. There are 4 simple steps an engine takes to work which are listed below.

1. “Intake: The piston (green) is pulled down inside the cylinder (gray) by the momentum of the crankshaft (gray wheel at the bottom). Most of the time the car is moving along, so the crankshaft is always turning. The inlet valve (left) opens, letting a mixture of fuel and air (blue cloud) into the cylinder through the purple pipe.”

2. “Compression: The inlet valve closes. The piston moves back up the cylinder and compresses (squeezes) the fuel-air mixture, which makes it much more flammable. When the piston reaches the top of the cylinder, the sparking plug (yellow) fires.”

3. “Power: The spark ignites the fuel-air mixture causing a mini-explosion. The fuel burns immediately, giving off hot gas that pushes the piston back down. The energy released by the fuel is now powering the crankshaft.”

4. “Exhaust: The outlet valve (right) opens. As the crankshaft continues to turn, the piston is forced back up the cylinder for a second time. It forces the exhaust gases (produced when the fuel burned) out through the exhaust outlet (blue pipe).”
