Systems for internal mixture formation
Direct-injection (DI) systems rely on solenoid-operated injection valves to spray fuel directly into the combustion chamber; the actual mixture-formation process takes place within the cylinders, each of which has its own injector (Figure 3). Perfect atomization of the fuel emerging from the injectors is vital for efficient combustion. Under normal operating conditions, DI engines draw in only air instead of the combination of air and fuel common to conventional injection systems. This is one of the new system's prime advantages: It
banishes all potential for fuel condensation within the runners of the intake manifold.
External mixture formation usually provides a homogenous, stoichiometric airfuel mixture throughout the entire combustion chamber. In contrast, shifting the mixture-preparation process into the combustion chamber provides for two distinctive operating modes:
With stratified-charge operation, only the mixture directly adjacent to the spark plug needs to be ignitable. The remainder of the air-fuel charge in the combustion chamber can consist solely of fresh and residual gases, without unburned fuel. This strategy furnishes an extremely lean overall mixture for idling and part-throttle operation, with commensurate reductions in fuel consumption.
Homogenous operation reflects the conditions encountered in external mixture formation by employing uniform consistency for the entire air-fuel charge throughout the combustion chamber. Under these conditions all of the fresh air within the chamber participates in the combustion process. This operational
mode is employed for WOT operation. MED-Motronic is used for closed-loop control of DI gasoline engines.

Answer 1

内部混合物形成的系统
Direct-injection (二)系统依靠螺管磁铁操作的射入阀门喷洒燃料直接地入燃烧箱; 实际混合物形成过程在圆筒之内发生，其中每一个有它自己的注射器(图3)。 涌现从注射器的燃料的完善的雾化是对高效率的燃烧至关重要。 在正常工作状态、在仅空气的DI engines凹道而不是空气的组合和燃料下共同对常规注射系统。 这是其中一新的系统的头等好处： 它
banishes在燃料结露的所有潜力在进气歧管的赛跑者之内。
External混合物形成通常提供在整个燃烧箱中的一个同源，化学计量学的航空燃料混合物。 相反，转移混合物准备过程入燃烧箱提供二种特别操作方式：
With有层次充电操作，只有混合物直接地在火花塞附近需要是可燃性的。 航空燃料充电的剩下的人在燃烧箱的可能单独地包括新和残余的气体，不用未烧过的燃料。 这个战略装备虚度光阴和部分节流孔操作的一个极端精瘦的整体混合物，与对燃料消费的比照减少。
Homogenous操作反射在外在混合物形成遇到的条件通过使用整个航空燃料充电的一致的一贯性在燃烧箱中。 在这些条件下所有在房间之内的新鲜空气参加燃烧过程。 操作的这
mode为WOT操作被使用。 MEDMotronic为二汽油发动机闭环控制使用。
