摘要： The aim of the invention is to provide a device for pre-heating the fuel for the cold start of a diesel powered internal combustion engine that does not require a bulky pencil-type glow plug. To this end, the inventive fuel nozzle is provided with a resistance heating layer (20) that especially consists of a ceramic material and that is disposed in the zone of the flow path of the fuel to be injected.

摘要： A fuel supply systems with two series-connected pumps and with fuel injection valves that inject fuel directly into a combustion chamber of an engine in which a starting process takes less time because of the small feed quantity of the second fuel pump. The system includes a valve device which assures that during the starting process the first fuel pump furnishes the fuel to the fuel valves at elevated feed pressure. In many cases, this elevated feed pressure suffices to start the engine in the quickest possible time. The apparatus and the method are intended for an internal combustion engine of a vehicle.

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： 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： 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.
