摘要： A temperature-dependent resistor or hot wire is extended over at least three anchoring points and to improve the measuring accuracy of the hot wire and to ensure sufficiently high temperatures over the entire active length of the hot wire during a cleaning step by burning, the hot wire is configured in the shape of loops at all anchoring points and the intersecting wire sections of the loops are conductively connected with one another. Current lead wires are preferably conductively attached to the hot wire by means of which the current is conducted to an electric control device. The end anchoring points are preferably electrically heated during an interruption of the measuring process of the hot wire and the hot wire may be directed in a W-shape over anchoring points whereat the hot wire is connected to the electric current, during the measuring process, via the two central, symmetrical anchoring points and upon an interruption of the measuring process, by means of a switching device, via the two end anchoring points.

摘要： A fuel delivery apparatus is proposed for mixture-compressing, externally ignited internal combustion engines, which serves to meter a fuel quantity adapted to the quantity of air induced and to regulate the fuel-air mixture in accordance with operational characteristics of the internal combustion engine. The fuel delivery apparatus comprises a fuel metering system actuated by an air measuring element arranged in the air induction line of the internal combustion engine, while the air measuring element has a control body which controls the size of the air induction tube cross-sectional area, a radial vane which is pivotably fixed in a work chamber, and a damping vane fixed in a damping chamber. The radial vane separates the work chamber into partial chambers and is impacted upon by the pressure upstream and downstream of the control body in such a manner that a force engages the radial vane which is capable of moving the control body in the direction of an enlargement of the controlled induction tube cross-sectional area and which acts counter to a return force. The damping vane separates the damping chamber into a pressure chamber and a throttle chamber; the pressure chamber is connected with atmospheric pressure or with the pressure upstream of the control body, and the throttle chamber, into which the damping vane moves during an opening movement of the control body, is connected with the pressure chamber via a throttle point. The throttle chamber and/or the pressure chamber of the damping chamber are capable of being connected with the induction tube section downstream of the control body by means of contro valves in accordance with operational characteristics of the internal combustion engine, for the purpose of influencing the fuel-air mixture furnished to the internal combustion engine.

摘要： A fuel injector has a piezoelectric or magnetostrictive actuator, which actuates a valve-closure member cooperating with a valve-seat surface a sealing seat. An hydraulic coupler includes a master piston, a slave piston, and a coupler volume formed in-between, the coupler volume being connected to a compensating chamber via a throttle. An elastic flexible section delimits the compensating chamber at least partially, and the coupler volume, the throttle, and the compensating chamber are filled with an hydraulic medium. The flexible section exerts a pressure on the hydraulic medium due to prestressing, and the force of a compression spring, which is braced either directly and/or via fixed components on the slave piston and the master piston, is directed with an initial stress in such a way that the force enlarges the coupler volume.
