Mafunso ndi Mayankho:

Что лучше непосредственный впрыск или распределенный впрыск? Непосредственный впрыск.  В нем большее давление топлива, оно лучше распыляется. Это дает почти 20% экономии и боле чистый выхлоп (более полное сгорание ВТС).

Как работает распределенный впрыск топлива? На каждую трубу впускного коллектора установлена форсунка. В момент выполнения такта впуска распыляется топливо. Чем ближе форсунка к клапанам, тем эффективней топливная система.

Какие бывают типы впрыска топлива? Всего принципиально отличающихся типов впрыска два: моновпрыск (одна форсунка по принципу карбюратора) и многоточечный (распределенный или непосредственный.
