Automobile

1) VTEC engine mechanism

VTEC (which stands for Variable Valve Timing and Lift Electronic Control) is an electronic and mechanical system in some Honda engines that allows the engine to effectively have multiple camshafts. As the engine moves into different rpm ranges, the engine's computer can activate alternate lobes on the camshaft and change the cam's timing. In this way, the engine gets the best features of low-speed and high-speed camshafts in the same engine.

                     In this mechanism, the acceleration of the engine is controlled by extending the time taken for the valve lift. It can be controlled by the synchronizing pin.

2) CVT [Continuous Variable Transmission]

It is the modern way of transmission by the friction rollers. The speed can be controlled without the gear box arrangement. It is mainly used in the ungeared vehicles.

3) Anderson CVT
