Abstract: The invention concerns an exhaust gas cleaning system for an internal combustion engine with at least one catalytically active component which is configured such that its catalytically active coating comprises at least a first region with high light-off temperature and a high temperature resistance and at least a second region with a low light-off temperature and a reduced temperature resistance (relative to the first region). The exhaust-gas-side surface of the catalytically active coating in the intake region of the catalytically active component has at least a partial diffusion layer, or is at least partially covered by a diffusion layer.

Abstract: In an inlet system for a two-cycle internal combustion engine which includes a cylinder with a piston reciprocating therein between a top dead center position and a bottom dead center position and in which at least two rows of scavenging air flow passages are arranged in separate flow planes around the cylinder adjacent the bottom dead center position of the piston which are closed by the piston when it is remote from the bottom dead center position, each of the separate flow planes includes independent air flow control components for independently controlling the admission of scavenging air to the scavenging air passages in the different flow planes.

Abstract: The invention relates to a charge information system to support the operator of an electric vehicle or hybrid vehicle, including the input of desired parameters for charging and operating the vehicle. The charge information system according to the invention comprises an input unit for putting the desired parameters into a computing unit which determines the required remaining charging time and displays it. Defining quantities are, among others, the charging efficiency or the desired range.

Abstract: The invention relates to a diesel internal combustion engine with an exhaust treatment device for the reduction of nitrogen oxides and with a fuel injection system comprising a high-pressure pump and at least one solenoid valve-controlled injection nozzle. The injection nozzle is actuated by an electronic control unit and is intended both for the primary injection, provided for the combustion, and for the additional injection, influencing the effectiveness of the exhaust treatment device. The fuel injection nozzle provided for the primary injection also provides for the secondary injection. The secondary injection takes place as a supplementary injection at the earliest in the region of the end phase of the combustion after the ignition top dead center.

Abstract: For control of the injection rate of a device for feeding fuel into the combustion chamber of an internal combustion engine, comprising an injection valve opening into the combustion chamber, which is used for taking compressed gas from the cylinder and injecting it together with the fuel supplied by a metering device, and further comprising a gas storage cell for holding the compressed gas, the proposal is put forward that a variable throttle be provided between the valve seat of the injection valve and the gas storage cell, whose flow cross-section can be controlled in accordance with load and speed parameters of the engine.
