The Power Generation System: Pistons and Crankshaft
At the heart of your car’s engine lies a remarkable system. It’s made up of pistons and crankshaft. These parts work together to turn the explosive force of combustion into the rotational energy that moves your vehicle.
As the pistons move up and down in the cylinders, they are driven by the power stroke. This is when the air-fuel mixture ignites, creating a strong downward force. This piston movement is then turned into crankshaft rotation through the connecting rods. These rods link the pistons to the crankshaft.
The crankshaft, with its unique design, changes the pistons’ linear motion into the circular motion needed to drive the vehicle’s wheels. This power stroke is key in the four-stroke cycle. It’s where the combustion event happens, providing the force needed to keep the engine running.
| Engine Component | Function | Key Features |
|---|---|---|
| Pistons | Convert the explosive force of combustion into mechanical energy | Typically made from lightweight aluminum alloy for exceptional heat conductivity |
