摘要： Method for measuring a fluid flow, in particular an air flow (L), flowing in a flow canal to an engine (VM) or from an engine (VM), by means of a fluid mass measuring means (3) connected to an evaluation means (2), wherein in a regularly performed cycle an operational parameter (D1, D2, . . . , Dn) characterizing the operating status of the engine (VM) is recorded, the data (M1, M2, . . . , Mn) supplied by the fluid mass measuring means (3) are recorded, at least one extreme value (Ep, En) is determined from the data (M1, M2, . . . , Mn) recorded since the beginning of a time period (t1, t2, . . . , tn), an average value (Wma) is determined from the recorded data (M1, M2, . . . , Mn), a pulsation amplitude (P1, P2, . . . , Pm) is determined by dividing the extreme value (Ep) by the average value (Wma), and the average value (Wma) is corrected by multiplying it by a correction factor (K11, K12, . . . , Kmn) which is selected in dependence on the operational parameter (D1, D2, . . . , Dn) and the pulsation amplitude (P1, P2, . . . , Pm) from a plurality of correction factors (K11, K12, . . . , Kmn) stored in a memory (12) of the evaluation means (2) and being determined in an operation test for the type of fluid mass measuring means (3) in relation to the type of engine.

摘要： An electrical camshaft phaser arrangement for controllably varying the phase relationship between a crankshaft and a camshaft in an internal combustion engine includes an adjusting gear drive unit formed as a three shafts transmission having a drive shaft connected with the crankshaft, an output shaft connected with the camshaft, and an adjusting shaft connected with the control shaft of an electrical machine. The electrical machine allows phasing the camshaft with regards to the crankshaft by increasing or decreasing control shaft speed, the control shaft being spinning during phase holding modes. The adjusting gear drive unit is configured such that an energy recovering mode is provided wherein a braking torque is applied to the control shaft in order to generate electrical energy.
