Abstract

The invention relates to a device in internal combustion engines provided with a supercharger (2) of the rotary screw compressor type and a compressed air assisted fuel injection system (8, 9, 10). According to the invention a rotary screw compressor (2) of a kind known as such is used as the supercharger, which compressor through a special, from the ordinary outlet port (13) separated, outlet port (21) delivers a minor air flow of high pressure after closing of the ordinary outlet port, which special port (21) by a pressure pipe (7) is connected to the fuel injection system (8, 9, 10) for pressurizing this.
