Izvoli najkraće moguće uvod u potpuno suprotni način rada benzinaca sa viškom vazduha, tipičan za direktno ubrizgavanje kao bitna razlika u odnosu na link i tekst koji si postavio za indirektno ubrizgavanje.
Iako koriste isti benzin prilično su različiti po tome kako rade pretežni deo vremena i koji su odnosi količina u izduvnim gasovima.
The stratified charge mode creates a small zone of fuel/air mixture around the spark plug, which is surrounded by air in the rest of the cylinder. This results in less fuel being injected into the cylinder, leading to very high overall air-fuel ratios of >8 with mean air-fuel ratios of 3...5 at medium load, and lambda =1 at full load.[11] Ideally, the throttle valve remains open as much as possible to avoid throttling losses. The torque is then set solely by means of quality torque controlling, meaning that only the amount of injected fuel, but not the amount of intake air is manipulated in order to set the engine's torque
due to its inherent lean burn, more nitrogen oxides are formed,[17] which sometimes require a NOx adsorber in the exhaust system to meet emissions regulations.[18] The use of NOx adsorbers can require low sulphur fuels, since sulphur prevents NOx adsorbers from functioning properly.[19] GDI engines with stratified fuel injection can also produce higher quantities of particulate matter than manifold injected engines,[20] sometimes requiring particulate filters in the exhaust (similar to a diesel particulate filter) in order to meet vehicle emissions regulation

Nije nešto novo pa da se ne zna. Od 1996.godine se primenjuje kod benzinaca a to je koliko godina već proteklo
