摘要： PROBLEM TO BE SOLVED: To protect internal combustion engines against fuel enrichment by stopping fuel supply to at least discrete cylinders and limiting the fuel cutoff time or frequency in a maximum permissible speed range or fully-loaded range. SOLUTION: On receiving input signals about wheel rotating speed from measuring devices 40 and 42, a control unit 34 diagnoses the slip trend of at least one driving wheel. When the wheel rotating speed exceeds a predetermined reference value, the control unit 34 outputs to another control unit 10 a signal urging it to reduce the torque of an internal combustion engine, and regulates the slippage that is based on the wheel rotating speed to a predetermined target value. The control unit 10 then controls the fuel quantity via an output line 12 and the ignition timing via another output line 16 and further limits or prohibits individual injection stops to protect the internal combustion engine in a maximum permissible speed range or fully-loaded range.

摘要： PROBLEM TO BE SOLVED: To contrive consistency between torque reducing control and additional functions in view of fewest harmful substance emissions by maintaining additional functions by EGR and tank ventilation during torque reduction mainly by ignition angle control. SOLUTION: An internal combustion engine is provided with an EGR duct 18 and a tank ventilation/exhaust duct 20 both connected to an intake pipe system 10 between a throttle valve 12 and an intake valve 16. The intake pipe system 10 has a fuel injection valve 22, and a combustion space 24 has a spark plug 26. Combustion gas is expelled out by a piston 28 into an exhaust pipe system 14 via an exhaust valve 30. An engine control unit 36 is connected with a solenoid valve 32 interposed in the EGR duct 18, the spark plug 26, the fuel injection valve 22, and another solenoid valve 44 interposed in the tank ventilation duct 20 via respective lines 34, 38, 40 and 42. In torque reduction mainly by ignition angle control, the additional functions of the EGR and tank ventilation are maintained.

摘要： The invention sets forth an arrangement for the aftertreatment of exhaust gases from a compression-ignition internal combustion engine, in which, to improve the operation of a reducing catalytic converter, a reducing agent is injected into the exhaust gas fed to the catalytic converter. Injection is performed by virtue of an electrically controlled metering valve which is combined in a common housing with a control valve. This control valve serves for the controlled introduction of compressed air supplied, in which a quantity of reducing agent made ready by the metering valve is prepared and introduced intermittently into the exhaust gas. This serves, in particular, to avoid urea deposition and clogging in the metering valve and the control valve and for the optimum preparation of the reducing agent introduced.

摘要： PCT No. PCT/DE90/00818 Sec. 371 Date Jun. 18, 1991 Sec. 102(e) Date Jun. 18, 1991 PCT Filed Oct. 26, 1990 PCT Pub. No. WO91/08383 PCT Pub. Date Jun. 13, 1991.An electrohydraulic valve control device for internal combustion engines in which a tappet volume for operating a valve piston arranged between an actuating cam operated cam piston and an engine valve can be reduced via a solenoid valve which is arranged in a drain passage. Arranged in this drain passage is a shut-off valve which is hydraulically actuated to open only when the valve piston has carried out a minimum stroke. This minimum stroke corresponds to a torque angle range of the camshaft in degrees of rotation during the opening actuation, in which, due to the shut-off valve, a control by the solenoid valve is not possible, whereby despite overlapping of engine valve opening times in a multi-cylinder engine, any overlapping of control times for the drain passages of individual engine valves, predetermined by the solenoid valve is prevented.

摘要： Fuel injection pump having a pump piston including a working space that is connected via a check valve with a reservoir closed off by a movable wall. A control line leads from this reservoir to a regulating cylinder. An adjustable regulating member is displaceably disposed in this regulating cylinder, permitting adjustment of the fuel quantity control slide according to the position of the regulating member. The subject of the invention achieves a simple construction for a fuel injection pump, for which only a small amount of drive power is required.

摘要： A fuel injector for an internal combustion engine, having a valve member which is axially displaceable in a guide bore of a valve body, has two guide areas with which it is displaceably guided in the guide bore, a first upper guide area being provided on the send of the valve member facing away from the combustion chamber and a second lower guide area being provided in an area of the valve member near the combustion chamber, a lower guide area separating an annular clearance which is formed between the valve member shaft and the wall of the guide bore and is connected to a high-pressure fuel inlet channel is separated from a lower pressure space opening onto the valve seat face when the fuel injector is closed, and opening this connection during the opening stroke movement of the valve member, and having a connecting throttle cross section between the annular clearance and the lower pressure space. This throttle cross section is designed as a throttlebore.

摘要： In a method and device for the open-loop control of an internal-combustion engine, the change in the torque caused by an influencing of the ignition angle is compensated for by a correspondingly adjusted influencing of the air inducted by the internal-combustion engine. Thus, the accelerator-pedal characteristic is hardly influenced in the case of a change in the ignition angle. The method and device can be used, for example, to accelerate the heating up of a catalytic converter after start-up of the internal-combustion engine. To reinforce the heating operation and to reduce emission, an intervention in the air/fuel ratio can be made at the same time, and a switching signal can be produced, for example, for a secondary air pump. The air inducted by the internal-combustion engine is generally influenced by an idle-speed actuator, which is arranged in a by-pass duct leading to the throttle valve. In the case of internal-combustion engines having an electronically controlled throttle valve, in place of the idle-speed actuator, the throttle valve can also be influenced accordingly. Weighting factors which depend on the operating state of the internal-combustion engine, are used to weight the influencing of the ignition angle, the idle-speed actuator, the throttle valve, and/or the air/fuel ratio.

摘要： A fuel-supply system for an internal combustion engine, particularly of a motor vehicle. The fuel-supply system is provided with a pump for delivering fuel into a storage chamber and for producing a pressure in the storage chamber. In addition, provision is made for a pressure sensor for measuring an actual value of the pressure in the storage chamber, as well as a pressure-control valve for influencing the pressure in the storage chamber. A control unit is provided with means by which the pressure in the storage chamber is controllable to a setpoint value. In addition, the control unit is provided with means by which the closed-loop control of the pressure in the storage chamber is able to be superseded by an open-loop control.

摘要： PROBLEM TO BE SOLVED: To reduce harmful emission after catalyst especially in the low temperature start process by mixing gas having a high oxygen content as a function of an operating point of an internal combustion engine in sucked air. SOLUTION: A thorttle valve 12 is interposed in an intake pipe 10 where atmospheric air flows through an air filter 14 by intake negative pressure, and a by-pass channel 20 is connected to an intake pipe 10 in such a manner as to by-passing the throttle valve 12. In the channel 20, a chamber 21 provided with a film 30 where only oxygen molecules can penetrate is disposed. The film 30 is preferably a film of one bundle of hollow fibers buried in synthetic resin. In the by-pass channel 20, a check valve 22 for preventing backflow in the channel 20 and a blower 24 capable of supplying air flow generated under a little high pressure to the film 30 is further provided. The by-pass channel 20 is opened and closed through an idling setting device 16 driven by motor control and at the time of low temperature start, a gas with a high oxygen content is supplied to an engine.
