What does ivtec mean?

Ivetec is the abbreviation of Honda intelligent variable valve timing system. Vitec system has been widely installed on new Honda models. In the process of engine rotation, when the engine changes from low speed to high speed, the electronic computer will automatically transfer the oil pressure to the small turbine in the transmission gear of the intake camshaft, and the small turbine can continuously adjust the throttle timing.

Attachment: introduction of ivtec:

When the engine rotates at low speed, the mixture required by the engine is not high enough to keep the speed stable and shorten the fuel consumption and pollutant emission. However, when the engine rotates at high speed, the engine needs more intake air to meet the demand of power output, and the phase and lift of the engine intake valve are the key factors related to the intake air of the cylinder.

After most ordinary engines are produced, the valve timing and valve lift are fixed. This kind of engine has necessary limitations, which can't meet the requirements of the engine for intake and exhaust at different speeds, so the variable valve timing adjustment mechanism came into being. This system is developed by Honda, and it is also the first valve adjusting system in the world that can adjust the valve opening and closing time and valve lift at the same time. It has also become one of the technologies imitated by many car companies and can be supplied during engine operation.
