摘要： A method is provided for determining a time duration for an electric actuation of a valve which has a coil drive, in particular of a direct-injection valve for an internal combustion engine. The method may include a deactivation of a current flow through a coil of the coil drive, such that the coil is in a currentless state, a detection of a time profile of a voltage induced in the currentless coil, a determination of the closing time of the valve on the basis of the detected time profile, and a determination of a time duration of the electric actuation of the valve for a future injection process on the basis of the determined closing time. A corresponding device and a computer program for carrying out the described method are also disclosed.

摘要： In a first operating state, the fuel metering of one of the cylinders is controlled in first metering pulses with the same pulse characteristic during a respective one working cycle, and the metering of fuel into the other cylinders by at least one second metering pulse with a different pulse characteristic. The first pulse number and characteristic is predefined such that the same fuel mass should be metered based on an assumed injection valve characteristic as with the one second metering pulse. Depending on the measurement signal, a correction value for the one cylinder is determined. To meter the fuel based on the assumed injection valve characteristic, a single first metering pulse would be generated during a respective one working cycle. The correction value for the one cylinder is used during the rest of the operation to adapt the first metering pulse in the second operating state.

摘要： The invention relates to a method for operating an internal combustion engine comprising a fuel pressure accumulator, in order to provide fuel at a nominal pressure, pressure in a fuel pressure accumulator being generated by means of a high-pressure pump. According to said method, the high-pressure pump is supplied with a fuel flow via a volume flow control valve. In a first operating mode, the pressure in the fuel pressure accumulator is set to the nominal pressure, by regulating the fuel flow of the fuel delivered to the high-pressure pump by means of the volume flow regulating valve. In a second operating mode, the pressure in the fuel pressure accumulator is set to the nominal pressure, i.e. more specifically, the pressure in the fuel pressure accumulator is reduced to the nominal pressure.

摘要： A method is provided for checking the efficiency of a catalytic converter with an oxygen probe upstream of the catalytic converter and of an oxygen probe downstream of the catalytic converter. A ratio of times in which the oxygen probe downstream of the catalytic converter and the oxygen probe upstream of the catalytic converter indicate a rich or a lean mixture value is formed. The catalytic converter has a sufficient efficiency if the value of the smaller amount of the ratio values is lower than a predeterminable limit value.

摘要： An internal combustion engine is equipped with a lambda regulating device, a catalytic converter disposed in an exhaust pipe of the internal combustion engine, a device for externally heating the catalytic converter to its operating temperature, and a secondary-air pump which injects additional air into the exhaust pipe. A method for controlling the fuel supply for the internal combustion engine includes injecting an additional fuel quantity during operation of a burner and during secondary-air injection, for heating the catalytic converter, as a function of engine air mass flow and an additional secondary-air quantity which is injected into the exhaust system.

摘要： A method for heating an exhaust gas catalyst of an internal combustion engine to an operating temperature during a warmup phase includes establishing an enriched mixture as a function of an engine operating state, with a control system. A sensor signal corresponding to a rich or lean mixture is output from a lambda sensor in an exhaust gas system. A quantity of secondary air is blown downstream of outlet valves and upstream of the lambda sensor in the exhaust gas system, from a secondary air pump. A feed quantity of the secondary air pump is pilot-controlled to a stoichiometric exhaust gas ratio, as a function of engine operating parameters, with the control system. The pilot control is corrected with a superimposed closed-loop control in accordance with the sensor signal, starting with operational readiness of the lambda sensor.

摘要： A method for carrying out a hot start in an internal combustion engine has a hot start condition that is recognized on the basis of the coolant temperature and the intake air temperature. A hot start identifier is stored when the coolant temperature and the intake air temperature have both reached a predetermined limit value at least once during a post-operation time after the internal combustion engine is turned off. At the next start of the internal combustion engine, the hot start is then carried out when the hot start identifier is stored and the coolant temperature still lies above its limit value. The method is thus based on temperature sensors that are already present in the motor control system. Therefore, no additional temperature sensors, for measuring the temperature of the fuel, are required.
