vvt-I (variable valve timing-intelligence)

Variable valve timing is one of the engine designs used in toyota and lexus. In fact it is the latest and the most effective designs in the market. due to this design it has been able to increase volumetric efficiency, developing higher engine torque(output). It has also benn able to control the vehicles fuel economy. how u might ask? simple by having a few kinds of design. first is the variable valve timing with solenoid, 2nd is the variable vlve timing and lift.as far as my knowledge spands, honda is also currently using this design except for a different name and slight difference in the mechanical design aspect.I will gather as much information as i can before i can actually explain what is variable valve timing. so wait for my coming posts......so check u later and peace out!
