Honda has developed a new next-generation 3.5 L V6 gasoline
engine using our latest Earth Dreams Technology. The overall design
objective for the engine was to reduce CO₂ emissions and provide
driving exhilaration.
The Earth Dreams Technology concept is to increase fuel economy
while reducing emissions. To achieve this and provide an
exhilarating driving experience, 3-stage Variable Valve Timing and
Lift Electronic Control (VTEC) was combined with the Variable
Cylinder Management (VCM) system. This valve train technology in
conjunction with Direct Injection (DI), resulted in dramatic
improvements in output (a 3.3% increase) and combined mode fuel
economy (20% reduction).
Helping to achieve Midsize Luxury Sedan level NV, a new mount
system was developed to reduce engine vibrations during
three-cylinder-mode operation.
In this paper, we will explain the 3-stage VTEC with VCM + DI
system, friction reducing technology, and the structure and benefit
of the new engine mount system.
