A bike motor is actually an internal combustion engine which provides a frontward thrust to the two wheeled machine we called motorcycle. In my previous article, we learned how 4 stroke engines work.

The goal of our project is to practice various modeling techniques, better understand the commands we use, and why we do. Now a days, electric energy is also used to power the bike motors. Newer models offer much smaller engines, some as small as an alternator. This little engine is carefully stationed in front of the back wheel, mounted low on the chassis. This animation will explain the inner workings and basic principle of twocycle engines also. Motorcycle engines work the same way that car engines do. In fact, i am not even sure they are still in production so i would not worry too much about having to repair one. The piston starts at the top, the intake valve opens, andthe piston moves down to let the engine take in a cylinderfull of air and petroleum. I wasnt just thinking of explosion in cylinders pushing pistons up and down.

Each engine has its own strengths and its own design quirks. Whats the difference between 2strokes and 4strokes. However, on the market are only two styles of engines. They consist of pistons, a cylinder block and a head, which contains the valve train. The dynamo contains a permanent magnet wound with coils of insulated wire.
