奔驰M270发动机与7G DCT变速器M270发动机首次应用是在新B级,它的结构设计能够兼容横置和纵置两种布局。这也是第三代缸内直喷技术BlueDIRECT首次应用在直列四缸发动机上,在一个冲程内实现最多五次燃油喷射的压电燃油喷嘴以及能够在一毫秒内连续释放四次电火花的多重火花点火系统是BuleDIRECT技术的核心,能够更好地提升燃烧效率,改善车辆的排放和经济性。也正是因为这两项技术的存在,使得这款涡轮增压发动机能够做到10.3的压缩
The first application of the Mercedes M270 engine and the 7G DCT transmission M270 engine is the new B-class, which is designed to be compatible with both horizontal and vertical layouts. This is also the first generation of in-cylinder direct injection technology BlueDIRECT first applied to the inline four-cylinder engine, in a stroke to achieve up to five times the fuel injection jet fuel nozzle and in a millisecond continuous spark discharge four sparks Ignition systems are at the heart of BuleDIRECT’s technology to better improve combustion efficiency and improve vehicle emissions and economy. It is also because of the presence of these two technologies, making this turbocharged engine can do 10.3 compression
