效率目标是决定传动系选择的关键之一,汽车的三种新型装置在经济性方面可以与和固定排量的火花点火发动机相匹配的传统四档手动或自动变速器(当变扭器锁止时)相抗衡。对利用模拟车辆城市行驶(EPA 循环)和等速行驶工况采用连续可变传动比和无限可变传动比的汽车变速器的燃油消耗量做了预测,还使用可变排量发动机进行了模拟试验。
The efficiency goal is one of the keys to deciding on the powertrain choice. The three new car models are economically compatible with the traditional four-speed manual or automatic transmission that matches a fixed-displacement spark-ignition engine (when the converter is locked ) Contend. Predicting the fuel consumption of a vehicle transmission with a continuously variable transmission ratio and an infinitely variable transmission ratio using simulated vehicle city driving (EPA cycle) and constant speed driving conditions, a simulation test was also conducted using a variable displacement engine .
