ABSTRACT:
An arrangement in an internal combustion engine comprises a membrane carbureter (10) having a fuel chamber (12) provided with a movable membrane (11) cooperating with a valve (17) for controlling the fuel supply to said fuel chamber. The air inlet of the carbureter is connected to a filter housing (31) provided with an air filter (32) for cleaning the inlet air, and a pressure chamber (13) is disposed adjacent said membrane and connected to said filter housing to control the fuel supply in relation to the pressure drop across said air filter (32). According to the invention, the membrane (11) is arranged in parallel with a wall (33) of the filter housing, and said wall is disposed adjacent to the pressure chamber (13) and provided with an opening (34) via which said pressure chamber communicates with the interior of said filter housing.
