    摘要: In order to control an internal combustion engine, a fuel mass that is to be supplied to the respective cylinder is determined according to a load variable. An additional fuel mass to be measured once is determined, when the measuring signal of an oxygen probe arranged downstream from a three-way catalytic converter is characteristic of at least one pre-determined residual oxygen part, according to the course of the measuring signal. A once reduced fuel mass is determined, when the measuring signal is characteristic of at least one pre-determined residual fuel part, according to the course of the measuring signal. A corrected fuel mass to be measured is determined according to the fuel mass to be supplied and optionally less the once reduced fuel mass or the fuel mass to be measured once. An actuating signal for controlling the injection valve is generated according to the corrected fuel mass to be supplied.

    摘要: To determine effect on a magnetic field caused by a lining structure in a wellbore, an array may be deployed into the wellbore lined with the lining structure. The array comprises a plurality of sensors including sensor A configured to operate as a transmitter, sensor B configured to operate as either a transmitter or a receiver, and sensor C configured to operate as a receiver. The array measures magnetic fields using sensor B as a receiver and sensor C in response to activation of sensor B as a transmitter and sensor A. A plurality of lining structure correction factors can be calculated based on the measured magnetic fields, based on the reciprocity of the sensors.

    摘要: A control system for a PWM inverter may reduce a DC component of an output of the inverter. An output voltage signal may be attenuated with a low-pass filter to produce a signal with a high DC content. A duty cycle of an output of the low pass filter may be determined with a zero-crossing detector. A calculation may be performed to determine a magnitude of a DC offsetting voltage that may offset the DC component of the inverter output. The inverter may be commanded to produce a DC offsetting voltage with an opposite polarity from the DC component of the inverter output. The opposite polarity DC offsetting voltage may effectively cancel the DC component of the inverter output. A monitoring system may employ an alternate system for determining the level of the DC component, thus providing a desirable redundancy to the system.

    摘要: An efficient method for parsing HTML pages identifies pages containing a mix of static and dynamic content. The pages are parsed to form abstract syntax trees (ASTs), which are then cached along with the pages. When a later version of a page is retrieved, it is compared against the cached version, and only those portions of the AST that contain different content are reparsed.

    摘要: An internal combustion engine is provided with at least one modulator for adjusting an air mass in a cylinder. It is also provided with an injection valve for metering fuel to which fuel is supplied via a fuel supply device. A maximum fuel quantity which can be metered to the cylinder per working stroke is determined. Depending on the maximum meterable fuel quantity, a maximum producible torque is determined. An air mass flow is determined depending on an air/fuel ratio to be adjusted and the maximum meterable fuel quantity is adjusted by controlling the at least one modulator for adjusting the air mass. The injection valve is controlled in accordance with the maximum meterable fuel quantity when the required torque is greater or equal the maximum producible torque.

    摘要: For this method, a portion of the exhaust gas is recirculated from the exhaust train via an external line to the intake manifold and is mixed with the fresh air supplied to the cylinder, and a further portion of the exhaust gas is supplied once again through the valves internally to the combustion space of the engine. The internally recirculated amount of exhaust gas is adjusted by controlling the cam phases (VVT) as a function of the engine load and engine rpm. A target value (VVT_EGR_SP) for the internal recirculation rate of the exhaust gas is calculated as the difference between the target value (EGR_SP) of the recirculation of the exhaust gas and the external recirculation rate of the exhaust gas (EXT_EGR_RATE).

    摘要: There is described a method for determination of an application time for a tank ventilation on an internal combustion engine. An excessive enrichment of the air/fuel mixture can be avoided by means of a timely application of injection correction as result of the tank ventilation. According to said method, a threshold value comparison is carried out for a modified lambda control deviation, made up of the lambda control deviation and a pseudo lambda control deviation, whereby the pseudo lambda control deviation depends on the deviation of the lambda values from a given lambda set value.
