Engine tuned for hybrid electric and continuously variable transmission applications |
摘要 |
An engine tuned for use with a hybrid engine or CVT has a relatively narrow torque curve that is roughly centered at the engine's rated speed, with less than 50% of the maximum torque provided throughout 80% of the range of engine speeds. The relatively narrow torque peak permits a variety of optimizations that improve fuel economy and reduce emissions.
