Abstract
Honda has successfully developed a new generation continuously variable transmission (CVT) for the 1996, 1.6L economy car, Civic series. The major development target to be achieved was; integration of the advantages of the conventional automatic transmission (AT) and CVT. In doing so, the engineers in charge aimed at further improvements in product attractiveness, fuel economy and driving performance. To reach the goal, the following technologies were required. 1)The start clutch layout to the output side (driven-side) of the belt shifting mechanism. 2)The full-electronic control system for the operation of the CVT. 3)The belt compatible to high engine power output and wide shift ratios. 4)The dual mass flywheel (DMFW) to reduce noise and vibration. As a result of combining CVT with the engine having power output of 95.7kw, variable valve timing, and lean burn technology, as well as having CVT totally controlled with engine system was good fuel economy, which is consuming only one liter of fuel every 17.2km under the Japanese 10-15 fuel economy standard measuring method.
