新型VR30DDTTエンジンの先進技術

摘要

新型VR30DDTTエンジンは新時代にふさわしい卓越した動力性能と環境性能を実現した.前型エンジンであるVQ37VHRからの主な性能向上代を下に記す.1.最大出力とトルクは各々72hp(53kW)と112Nm向上2.燃費性能は約7%向上(USComb.)3.排気性能は触媒活性化時間を約半減し，HC排出量は約65%低減(LA4-CH1山目).%VR30DDTT was developed as a successor to the VQ37VHR engine. This engine offers superior driving performance combined with excellent environmental performance. This paper describes advanced technologies which VR30DDTT engine has been applied to achieve overwhelming driving performance and excellent environmental performance.
