摘要： Internal combustion engines which are operated using ethanol exhibit an improved capability for lean-burn running. The lean-burn running limit with a higher ethanol proportion is displaced in the direction of lean. This link between the lean-burn running limit and the ethanol proportion of the fuel is used to determine the ethanol proportion. To determine the lean-burn running limit, a fuel quantity is injected into a cylinder in the operating range of the overrun fuel cut-off, with which fuel quantity no combustion of the air/fuel mixture occurs, and the fuel quantity is increased continuously until combustion occurs; the smooth running of the engine is monitored for this cylinder and the lean-burn running limit is detected as reached if the smooth running exceeds a predefined threshold value. The ethanol proportion is then deduced from the increase in the injected fuel quantity which is required to reach the lean-burn running limit.

摘要： In a method and a device which allow determination of the combustion lambda value of an internal combustion engine having at least two combustion chambers without using a lambda sensor, a predetermined first fuel quantity is metered to the first combustion chamber and a predetermined second fuel quantity is metered to the second combustion chamber, the first fuel quantity is reduced by a predetermined amount and the second fuel quantity is increased by the same predetermined amount. A first engine noise, associated with the first combustion chamber, and a second engine noise, associated with the second combustion chamber, are determined. The combustion lambda value is determined based on the first engine noise value and second engine noise value.

摘要： An internal combustion engine has at least one cylinder and an exhaust gas tract, which contains a component to be protected. An estimated dynamic component temperature of the component is determined in accordance with at least one operating variable of the internal combustion engine, taking into consideration the dynamic behaviour of the section of the internal combustion engine. An estimated stationary component temperature of the component is determined in accordance with at least one operating variable of the internal combustion engine without taking into consideration the dynamic behaviour of the section of the internal combustion engine. An actual value is determined for the component temperature of the component in accordance with the estimated dynamic and stationary component temperatures of the component to be protected.

摘要： The invention relates to a method for controlling an internal combustion engine with a motor control system that adjusts the exhaust-gas temperature by influencing the air-fuel mixture. Said motor control system has a temperature model so as to determine a preset temperature for a component in the exhaust manifold, which is achieved after a longer period of time while maintaining current operating and driving conditions. The motor control system regulates the exhaust-gas temperature depending on the preset temperature for the purpose of component protection.

摘要： In a method for regulating an air/fuel ratio, and in a method for recognizing a fuel quality, a lambda sensor is provided in the exhaust of the internal combustion engine, wherein after fueling of the tank the second adaption value is first adjusted due to a deviation of the lambda signal from the target signal occurring such that the lambda signal oscillates again about the target value, wherein the second adaption value is determined as a function of the current adaption value and as a function of the currently determined quality of the fuel. In a method for recognizing a fuel quality, particularly of a mixture ratio of two types of fuel, the lambda signal of the lambda sensor is analyzed for recognizing the quality.
