ABSTRACT:
A throttle valve pipe is proposed, which is used for fuel mixture formation for mixture-compressing internal combustion engines with externally supplied ignition. The throttle valve pipe includes an intake conduit and a throttle valve is disposed therein and to control fuel flow. From upstream of the throttle valve fuel can be ejected by an injection valve in the direction toward the throttle valve. The throttle valve is made of ceramic and on its surface which faces the injection valve this valve is provided with an electric heating resistor film. In the pivoting region of the throttle valve, a liner of ceramic is inserted into the intake conduit and the additionally liner surface which forms part of the intake conduit is provided with an electric heating resistor film.
