Abstract

An air injection arrangement 101 for a combustion engine too comprising a combustion engine module 150. The air injection arrangement 101 comprises an air inlet 195 arranged to guide air into a main air channel 220 at an air pressure. The main air channel comprises a branch into a first air channel and a second air channel. The first air channel is arranged to be connected to an air intake of the combustion engine, andthe second air channel is arranged to be connected to an air flow conduit for cooling the combustion engine module.
