ABSTRACT:
A fuel supply system is proposed for mixture-compressing internal combustion engines having externally supplied ignition. The fuel supply system includes an air intake tube delimited by an air filter, the air intake tube having a conical section downstream of which an arbitrarily actuatable throttle device is disposed. Associated with the conical section of the air intake tube is an air bypass line in which an air flow rate meter provided with a temperature-dependent resistor is disposed. The quantity aspirated by the engine is determined by this air flow rate meter. A fuel injection valve is disposed in such a manner that on one side it protrudes into the interior of the air filter and on the other side, with a slender mouthpiece, it protrudes approximately through the conical section. The fuel can be injected into the gap between the throttle device and the air intake tube wall by means of this mouthpiece. The fuel supply system according to the invention has a very low structural height.
