Audi using supplementary port fuel injection to address particulates from gasoline direct injection

Green Car Congress

In part-load operation, the indirect injection supplements direct gasoline injection to improve fuel economy and to reduce the output of particulates from the engine. GDI technology provides fuel efficiency benefits from charge air cooling, more facile turbocharging, and the downsizing that these permit. Resources. Earlier post.)
