摘要： A method and device for diagnosing a low pressure exhaust gas recirculation system (LPEGRS) of an internal combustion engine having an intake area for supplying fresh air which includes in succession in the flow direction a first section having a low pressure in which an air mass flow sensor is situated, a compressor and a second section having a high pressure, the engine exhaust area including a second section having a low exhaust gas pressure, and the LPEGRS which has an adjustable LPEGR valve recirculating at least a portion of the exhaust gas in the second section of the exhaust area to the first section of the intake area. The fresh air mass flow taken in is measured by the air mass flow sensor, the total mass flow flowing through the compressor being ascertained, the LPEGR mass flow being ascertained from the difference between the total mass flow and the fresh air mass flow taken in, an estimated value being calculated for the LPEGR mass flow, the difference between the ascertained LPEGR mass flow and the estimated value being formed, and an error signal being output for a deviation. The procedure is for detecting exhaust gas-relevant errors.

摘要： A method for operating an internal combustion engine (10), the internal combustion engine (10) having a feed line (14) for feeding an air mixture into the internal combustion engine (10), the feed line (14) having a first section (27) at a comparatively low pressure, a compressor (22) for compressing the air mixture fed in, and a second section (29) at a comparatively high pressure arranged in series in the feed direction, the internal combustion engine (10) having an exhaust line (12) for discharging exhaust gas from the internal combustion engine (10), the exhaust line (12) having a section (43) in which the exhaust gas is at a comparatively low pressure, and the internal combustion engine (10) having an exhaust gas recirculation system (50) which recirculates into the first section (27) of the air feed (14) at least part of the exhaust gas which flows through the section (43) of the exhaust line (12) at the comparatively low pressure, the recirculated part of the exhaust gas and fresh air fed in forming the air mixture flowing through the feed line (14). A mass flow (71) of the recirculated part of the exhaust gas is determined by means of the following steps: (a) determination of a mass flow (72) flowing through the compressor (22); (b) determination of a mass flow (70) of the fresh air fed in; and (c) subtraction of the mass flow (70) determined in step (b) from the mass flow (72) determined in step (a).

摘要： The present invention may relate generally to a circuit for converting a first digital signal having a first sample rate to second digital signal having a second sample rate. The circuit may comprise a cascaded integration-comb filter and a fractional sample rate converter. The fractional sample rate converter may be configured to perform fractional sample rate conversion. A first of the cascaded integrator-comb filter and the fractional sample rate converter may be configured to receive the first signal having the first sample rate and to generate a third digital signal having a third sample rate different from the first and second sample rates. A second of the cascaded integrator-comb filter and the fractional sample rate converter may be configured to receive the third signal having the third sample rate and to generate the second signal having the second sample rate.

摘要： In an internal combustion engine, at least one rotation variable characterizing the rotational movement of a crankshaft is ascertained cylinder-specifically. It is provided that, in an operating state in which differences and/or fluctuations of the rotation variable are basically a function of a combustion position, the instant of a fuel injection is adapted cylinder-specifically in order to reduce the differences and or fluctuations.

摘要： To enable operation of an internal combustion engine even without the signals of a phase sensor while nonetheless enabling an emergency driving function in the case of a disturbance of a crankshaft signal acquired by a crankshaft sensor, a cylinder pressure is acquired using a cylinder pressure sensor and it is checked whether the cylinder pressure reaches a prespecifiable threshold value. When the threshold value is reached or exceeded, an angular position associated with the threshold value is inferred. The angular position is then made available for an operation of the internal combustion engine.
