Advanced technology Variable Valve Timing and Lift Electronic Controlled (VTEC) Honda innovation results show different mechanisms. The main difference is the inclusion of valve movement. In the 16 valve engine, there is two of each incoming and exhaust valves in each cylinder.
VTEC is applied only on the intake valve. In this valve controlling the efficiency of the engine more powerful. The assumption, the process does not require disposal of the variable valve opening for the more smoothly the exhaust, engine work will be more lightly.
In VTEC engine, the second intake valve does not always move together. For example, at low speed there is only one valve is opened. Opening was also relatively small because the characters are punched camshaft valve is suitable for low speed. This condition is considered fit for the machine. Since at low rpm a lot of unnecessary air supply. In addition, there could be air turbulence to help mix the fuel. Engines so efficient, efficient, environmentally friendly too.
With increasing engine speed, air supply needs are also increasing. Directly answered by the second valve. Larger opening for nok chamshaft have a higher degree of character. Fun, had joined the first valve to open wider. This is because there are pins that connect the rocker arm and push pin. This will automatically lock the second pin rocker arm. Because the second rocker arm which is driven by the camshaft duration nok higher, so follow the movement of the first valve.
