| Abstract;A 1.3L 3-stage i-VTEC VCM engine, which satisfies both low fuel consumption and low emission requirements, was developed for the 2006 CIVIC Hybrid. In the development of this engine, friction was greatly reduced and volumetric efficiency was increased. In addition, VTEC technology was evolved to realize a 3-stage i-VTEC VCM that enables 3-stage valve motion switchover at low and high engine speeds and during cylinder idling. With the increased motor output, it is possible to run the automobile on the motor alone over a wider range of driving conditions, and to realize a further reduction in fuel consumption. The newly developed engine, higher power motor and more efficient CVT transmission enable the 2006 CIVIC Hybrid to achieve better vehicle dynamic performance and a fuel consumption of 31.0km/L in the 10-15 mode. In addition, the performance of the high density 2-bed, 3-way catalyst has been increased, realizing low emissions equal to 75% of the low emissions standard for fiscal 2005. (author abst.) |
