A system with “Variable Valve Timing –intelligent by Electric motor (VVT-iE)” has been newly developed to realize requirements for lower fuel consumption and lower exhaust gas emission, as well as higher performance. The system has initially been adopted for the intake valve train of Toyota’s new 4.6 and 5.0 litter V8 SI engine. The VVT-iE is composed of a cam phasing mechanism connected to the intake camshaft and a brushless motor integrated with an intelligent driver unit. The developed motor-actuated system is completely free from operating limitations by conventional hydraulic VVT. This new system leads to advantages in reducing cold HC and also achieves further reductions in fuel consumption.
