缸内直喷式汽油机正在不断普及 ,均质燃烧和层状燃烧是很重要的内容。按照发动机的运转工况灵活地运用这两种燃烧方式可同时实现最大功率输出和最低油耗率。 均质燃烧即为普通燃烧方式 ,燃料和空气混合形成一定浓度的可燃混合气 ,整个燃烧室内混合气的空燃比是相同的 ,经火花塞 In-cylinder direct injection gasoline is constantly ubiquitous, homogeneous combustion and stratified combustion is very important content. In accordance with the engine operating conditions flexible use of these two combustion modes can achieve maximum power output and minimum fuel consumption. Homogeneous combustion is the normal combustion mode, the fuel and air mixture to form a certain concentration of combustible mixture, the entire combustion chamber mixture of air-fuel ratio is the same, the spark plug
