How does an Engine work?
An internal combustion engine creates mechanical motion by igniting an air/fuel mixture. The power created by the engine is used to drive your car’s wheels and propel you down the road.
Although there are many parts inside the engine, the pistons and crankshaft are some of the most important. When the air/fuel mixture is ignited inside one of the engine’s cylinders, the explosion forces the corresponding piston downward, causing it to rotate the crankshaft. The torque or twisting motion of the crankshaft is transferred from the engine, through the car’s drivetrain and to the drive wheels.
