日前,在2012北京国际道路运输、城市公交车辆及零部件展览会上,潍柴动力推出新能源“WN20”动力总成。该动力总成是一款电混合化4～12升柴油机或天然气国Ⅳ、国Ⅴ发动机和5～16挡自动变速系统的总成组合,具备整车改动较小、应用于10～12米公交车的节油率达30%、8年运行可直接减少二氧化碳排放量80吨等优点。据《商用汽车新闻》记者了解,2011年玉柴也推出过一款混合动力总成系统,采用作用于离合器总泵的自动控制方式的玉柴专利技术,在保持传统离合器机构的同时,又能实现自动离合器控制,一旦电控系统失效,驾
Recently, at the 2012 Beijing International Road Transport, Urban Bus and Parts Exhibition, Weichai Power launched a new energy “WN20” powertrain. The powertrain is an assembly of electric hybrid 4 ~ 12 liter diesel engine or natural gas country Ⅳ, national Ⅴ engine and 5 ~ 16-speed automatic transmission system, with minor vehicle changes, used in 10 to 12 meters of public transport Car fuel economy rate of 30%, 8 years of operation can directly reduce the carbon dioxide emissions of 80 tons and so on. According to “Commercial Vehicle News” reporter learned that in 2011 Yuchai also introduced a hybrid powertrain system, the use of clutch master cylinder automatic control of Yuchai patented technology, while maintaining the traditional clutch mechanism, but also to Automatic clutch control, once the electronic control system failure, driving
