摘要： A method and an apparatus for determining the temperature of a gas charge in a cylinder of an internal combustion engine increase the accuracy with which the temperature of the gas charge is determined. The gas charge includes a residual gas portion and a fresh gas portion. The temperature of the gas charge is determined by ascertaining the temperature of the fresh gas portion, the proportion of the fresh gas portion in the gas charge, the temperature of the residual gas portion, and the proportion of the residual gas portion in the gas charge. The temperature of the gas charge is calculated based on these ascertained quantities.

摘要： The invention is directed to a method for determining a load signal of an internal combustion engine having an intake pipe with a pressure sensor, external exhaust-gas recirculation (EGR) and an EGR valve. A load signal (tl) is computed in a circuit arrangement which is proportional to the mass inducted per revolution of the engine. The computation is made in dependence upon measured intake-pipe pressure (ps) and the speed (n) of the engine in rpm. On the one hand, the method makes a simple adaptation possible, while, on the other hand, a correct load signal is formed also in steady-state operation and, in this way, reduced exhaust-gas emissions of the engine are made possible. The exhaust-gas mass flow flowing through the EGR valve is determined by converting the exhaust-gas mass flow into an rpm-dependent signal. The rpm-dependent signal is filtered in a filter simulating charging operations in the intake pipe. A corrective signal (scorr) proportional to the exhaust-gas mass inducted by the engine per revolution thereof is determined and this corrective signal (scorr) is subtracted from the load signal (tl) to generate and output the corrected load signal (tlcorr).

摘要： The invention relates to a method and a control arrangement for the metering of fuel in an injection system, especially for engines having an exhaust-gas turbocharger. The inducted air mass in the intake manifold (2) is measured as a primary control quantity by an air mass measuring apparatus (1) for the metering of fuel and the cylinder charge is computed via a control apparatus (3). A switchover to a substitute signal (P) as the primary control quantity takes place when a leak (8) is detected in the intake manifold (2) via a change of stored and actual pressure conditions.
