Motorcycle Engine Parts Name With Picture Pdf
Motorcycles have always been a symbol of freedom and adventure. The rumble of the engine, the wind in your hair, and the open road ahead make for an exhilarating experience. But have you ever wondered what makes your motorcycle go? In this article, we will explore the different parts of a motorcycle engine and their functions. We will also provide pictures and a downloadable PDF for your convenience.
1. Piston
The piston is a cylindrical component that moves up and down within the cylinder. It is connected to the crankshaft via a connecting rod. When the fuel-air mixture is ignited, it creates pressure that pushes the piston down, which in turn rotates the crankshaft.
2. Crankshaft
The crankshaft is a shaft that converts the linear motion of the piston into rotational motion. The connecting rod is attached to the crankshaft, and when the piston moves up and down, it rotates the crankshaft. The crankshaft is supported by bearings, which allow it to rotate smoothly.
3. Cylinder
The cylinder is a tube-shaped component that houses the piston. The fuel-air mixture is injected into the cylinder, where it is compressed by the piston. The ignition of the mixture creates pressure that pushes the piston down, which in turn rotates the crankshaft.
4. Cylinder Head
The cylinder head is the top part of the cylinder that closes it off. It contains the valves, which allow the fuel-air mixture to enter the cylinder and the exhaust gases to exit. The cylinder head also houses the spark plug, which ignites the fuel-air mixture.
5. Valves
The valves are small components that control the flow of fuel-air mixture and exhaust gases into and out of the cylinder. The intake valve opens to allow the mixture to enter, and the exhaust valve opens to allow the gases to exit. The valves are operated by the camshaft.
6. Camshaft
The camshaft is a shaft that operates the valves. It has a series of lobes that push on the valves to open and close them at the correct time. The camshaft is driven by the crankshaft via a timing chain or belt.
7. Timing Chain/Belt
The timing chain or belt is a component that connects the crankshaft to the camshaft. It ensures that the valves open and close at the correct time relative to the position of the piston. It is important to maintain the timing chain or belt to ensure that the engine runs smoothly.
8. Spark Plug
The spark plug is a small component that ignites the fuel-air mixture in the cylinder. It is threaded into the cylinder head and has a small electrode that creates a spark when an electrical current is applied. The spark ignites the mixture, creating pressure that pushes the piston down.
9. Fuel Injector/Carburetor
The fuel injector or carburetor is a component that mixes fuel and air in the correct proportions to create a combustible mixture. The fuel injector sprays fuel into the cylinder, while the carburetor mixes fuel and air and sends it to the cylinder.
10. Oil Pump
The oil pump is a component that circulates oil throughout the engine. It is driven by the crankshaft and ensures that all the moving parts are lubricated, reducing friction and wear. It is important to maintain the oil level and change it regularly to ensure that the engine runs smoothly.
Conclusion
In conclusion, motorcycles are complex machines that rely on a variety of engine components to run smoothly. Understanding these components and their functions can help you better maintain your motorcycle and diagnose any issues that may arise.
