i-VTEC Economizes BBM and Low of Emission
Friday, January 16, 2009
If VTEC worked step by step at revolution of engine which has been determined. For i-VTEC, governing “timing” and valve lift height changes continually or leads to progressive transformation. So, if when revolution of engine changed, time of opening and closed induction valve and exhaust also changes.
Working condition like that making engine to work more efficient. Can yield energy and twist in stretch is more breadth.
For i-VTEC, when automobile accelerates at a speed of quicker, valve lift height also ever greater. Quicker time of opening and closes farther out. On the contrary, if when automobile runs slow, valve lift height minimized. Time opens it is slower and time closes quicker.
Instead at low revolution, one of pelatuk valve is non to activates. In this way, number of fuels which given to combustion chamber can in lessening or applies lean mixture. Result of his, besides reducing exhaust emission of gas, also economizes consumption of fuel. So, the mode of action thin differences with the elder brother Si-VTEC!
Very profits, but mechanism of engine thus adds complicated!
