In order to develop an internal combustion engine with a carburettor, in particular with a diaphragm carburettor (100) with an inlet section (11a), a carburation section (11), a throttle valve section (12), a partial load and a main jet chamber (25, 38) and a fuel feed line (16) having a fuel pump (18), which line is connected to a fuel tank (15) via a fuel line (14) and which is connected to a filter chamber (20), an intake section (40) preconnected to the carburettor (100) and comprising an inlet pipe (42), an air filter (43) and an intake manifold (44), an inlet section (41) post-connected to the carburettor (100) and comprising an intermediate flange (45), an intake duct (46) and an overflow duct (47), in such a way that the principle of additional injection under all starting and environmental conditions leads to problem-free starting, it is proposed that a fuel return line (60) be provided which is connected at one end (61) to the fuel feed line (16) and at its other end (62) to the fuel tank (15), in the length of which a flow resistance (throttle) (59) is arranged. …<IMAGE>… |
