摘要： PCT No. PCT/DE86/00250 Sec. 371 Date Jun. 25, 1987 Sec. 102(e) Date Jun. 25, 1987 PCT Filed Jun. 13, 1986 PCT Pub. No. WO87/02741 PCT Pub. Date May 7, 1987.A starting control for fuel injection systems of internal combustion engines is suggested in which an injection time (teVER), which is dependent on the engine starting temperature (TMS), is determined in the starting phase. In the starting phase, this injection time (teVER) follows the curve of special starting characteristic lines. A continuous transition to performance characteristics injection time (teKF) is effected by means of a comparator. A smooth transition from the starting phase to normal operation is obtained in this way.

摘要： An actuating device is proposed which is used to adjust a throttle valve disposed in the intake tube of an internal combustion engine. The actuating device includes a gas pedal adapted to engage an actuating lever, which is supported rotatably relative to a throttle valve shaft, so as to pivot counter to the force of a restoring spring. Connected to the actuating lever is a follow-up drawing spring, which is secured with one end to an intermediate lever provided with a cam disk having a curved camming surface which surface a lever arm is supported so as to operate a damper element. The intermediate lever is rotatably supported with respect to the throttle valve shaft and with a coupling stop engages a throttle valve lever, which is connected to the throttle valve shaft such that relative rotation between them is prevented. The throttle valve lever is drawn against the coupling stop by means of an uncoupling spring disposed between the intermediate lever and the throttle valve lever. An idling actuator also engages the throttle valve lever. When the actuating lever is actuated in the clockwise direction, the intermediate lever is drawn in a damped follow-up manner by the follow-up drawing spring to adjust the throttle valve via the throttle valve lever.

摘要： PCT No. PCT/DE85/00366 Sec. 371 Date Jul. 2, 1986 Sec. 102(e) Date Jul. 2, 1987 PCT Filed Oct. 5, 1985 PCT Pub. No. WO86/03258 PCT Pub. Date Jun. 5, 1986.An adaptation method for a position detection member, particularly for detection of the position of the throttle valve of an internal combustion engine in a motor vehicle, is suggested, wherein a plurality of position receivers have a common drive and scan a plurality of overlapping path areas with different resolutions. The adaptation is effected in the overlapping path areas. In so doing, a correction value (ki) is formed, and the measured values (M2) of the path area to be adapted is added to it. A new correction value (Ki+1) is formed in each instance from the differential value (D) between the corrected measured value (W2) of the path area to be adapted and a desired value (T (W1)) for this path area. In so doing, the desired value is taken from an assignment table by means of which measured values (W1) of another path area forming a measurement basis are assigned desired values for the path area to be adapted. A very high accuracy can be achieved by means of this adaptation in spite of low-cost manufacture with relatively high allowable tolerances of the position detection member.

摘要： A fuel supply line for use with fuel injection devices of internal combustion engines is proposed, having supports to contain fuel injection valves. The fuel supply line has an elastic wall section, with which is connected a rigid wall section and on which are fastened the supports. The elastic wall section is elastic to the extent that it damps the pressure pulsations of the fuel in the fuel supply line, whereas the rigid wall section assures the required rigidity of the fuel supply line.

摘要： PCT No. PCT/DE90/00231 Sec. 371 Date Nov. 4, 1991 Sec. 102(e) Date Nov. 4, 1991 PCT Filed Mar. 23, 1990 PCT Pub. No. WO90/13738 PCT Pub. Date Nov. 15, 1990.A method is introduced of checking the drivability of a tank-venting valve (TEV) and of an idle actuator. After actuating the TEV, an additional air/fuel mixture is supplied to the intake region of an internal combustion engine having an air/fuel ratio which can be equal to that at which the engine usually operates ( lambda 0) or greater or less than lambda 0. Reactions of a lambda -control and/or of an idle control can be evaluated in dependence thereon. It is advantageous that a check is made independently of how intense the additional air/fuel mixture is enriched with fuel.

摘要： The invention is directed to a method for controlling the no-load speed of an internal combustion engine wherein the position of the throttle flap in the intake tube of the engine is varied as a function of the speed of the engine and of a position signal defining the position of the throttle flap. The variation of the throttle flap position takes place, however, only whenever the throttle flap has assumed a specific, predeterminable position and whenever the engine speed has remained virtually constant over a likewise predeterminable period of time. An embodiment in the form of a flow chart is described by means of which the method according to the invention can be realized.
