汽车发动机电子点火系统优化设计

Optimization design of engine electronic ignition system for an automotive engine

与上一代的M272发动机相比,梅赛德斯奔驰M276发动机的在动力性、经济性、排放等方面均有出色的表现。M276发动机采用第三代ECI点火系统,以满足日趋苛刻的燃油排放标准,并降低油耗水平,配合修改后的发动机停止/启动系统,理论上相较M272发动机最高能节省24%的燃油消耗量。

Compared with the previous generation of M272 engine,Mercedes-Benz M276 engine has excellent performance in power,economy,emissions and other aspects.The M276 engine uses the third generation ECI ignition system to meet the increasingly stringent fuel emission standards and reduce fuel consumption.The modified engine stop/start system can theoretically save up to 24%fuel consumption compared with the M272 engine.
