摘要： A method for operating an internal combustion engine with at least one working piston with a variable compression ratio, which can be changed as a function of an operating state of the internal combustion engine, the method including the steps of: detecting, with a knock sensor, when the compression ratio is too high; reducing the compression ratio (V) when the knock limit (L) is at least reached by a first, predetermined value (V1), which is a function of the operating state, over a first, predetermined time period (t1-t0); subsequently increasing the compression ratio (V) by a second, predetermined value (V2) over a second, predetermined time period (t2-t1) until the knock limit (L) is at least reached again; and determining at least one of the first predetermined value (V1), the first time period (t1-t0), the second predetermined value (V2), and the second time period (t2-t1) as a function of load demand on the internal combustion engine.

摘要： A direct injection internal combustion engine, especially an Otto engine, is provided with layered lean operation and internal exhaust-gas recirculation. An exhaust-gas aftertreatment for reducing Nox using an Nox storage catalyst is also provided. This combination is to achieve the highest possible exhaust-gas recirculation rates with the lowest HC and Nox emission values. A tumble flow is provided for the incoming fresh gases, which may contain recirculated exhaust gas from external exhaust-gas recirculation. The swirl axis of the incoming fresh gases therefore extends substantially crosswise to the piston movement. This results in an emissions-reducing, optimal mixture inside the cylinder during the layered lean operation.

摘要： A device for supplying exhaust gases from an internal combustion engine to a catalytic converter, having multiple exhaust gas supply lines including at least one exhaust gas supply line that serves as a heat-conveying line to promote a transfer of exhaust gas heat to the catalytic converter and at least one other exhaust gas supply line that serve as a heat exchanger to promote an extraction of heat from the exhaust gas upstream of the catalytic converter. A switchable control mechanism controls a flow cross-section of at least one of the exhaust gas supply lines. The exhaust gas supply lines are arranged as a bundle of pipes including individual pipes which are spaced apart and extend to the catalytic converter so that the exhaust gas supply line that is the heat-conveying line is arranged as an inner pipe in the bundle and is surrounded around its circumference by the exhaust gas supply lines that are heat exchangers, which are spaced some distance from one another in a circumferential direction of the heat conveying line. The exhaust gas supply line that is the heat-conveying line has a cross-section that is smaller than a cross-section of the exhaust gas supply line that is the heat exchanger.

摘要： A method relates to operating an internal combustion engine in the form of an Otto engine, especially of a motor vehicle. Otto engine fuel (i.e., carburetor fuel, spark ignition engine fuel), such as gasoline or ethanol (E85), are directly injected into at least one combustion chamber of the internal combustion engine with at least one fuel injector. Optionally, instead of injecting ignition spark engine fuel or in addition, the internal combustion engine is operated with gas, especially CNG (compressed natural gas) or LPG (liquefied petroleum gas). During operation of the internal combustion engine with gas only, the engine is automatically switched to the operation with spark ignition engine fuel for a predetermined period, or the engine is switched to the operation with spark ignition engine fuel in addition to the operation with gas, in such a manner that a predetermined quantity of the carburetor fuel flows through the at least one fuel injector. The engine is then automatically switched back to the operation with gas only.

摘要： A method is for controlling an overrun condition in a hybrid vehicle having a combustion engine and additionally at least one electric motor as well as an overrun fuel cutoff, which interrupts a fuel supply to the combustion engine when the vehicle is in an overrun condition and restores the fuel supply when the combustion engine reaches or falls below a restoring speed. At least in a combustion engine at operating temperature, the fuel supply is restored at a restoring speed of at most 200 min−1, e.g., at most 100 min−1 above an idling speed of the combustion engine. The restoring speed may be in the range of the idling speed or only slightly above the latter. The restoring speed is thus clearly lowered as compared to the usual restoring speeds and extends the overrun fuel cutoff phases and thus reduces fuel consumption.
