Arrangement in an internal combustion engine

Abstract

Abstract An arrangement in an internal combustion engine comprises a diaphragm carburettor (10) with a fuel chamber (12) which has a moving diaphragm (11) which interacts with a valve (17) to control the fuel supply to the fuel chamber. The air inlet of the carburettor is connected to a filter housing (31), which is provided with an air filter (32) for cleaning the intake air, and to a pressure chamber (13), which is arranged in the vicinity of the diaphragm and is connected to the filter housing to control the fuel supply with reference to the pressure drop across the air filter (32). According to the invention, the diaphragm (11) is arranged parallel to one wall (33) of the filter housing and this wall is arranged in the vicinity of the pressure chamber (13) and provided with an opening (34) via which the pressure chamber is connected to the interior of the filter housing. <IMAGE>
