摘要： It is described a method to cause the torques produced by each cylinder (10) of a multi-cylinder internal combustion engine to be substantially equal, said engine including a rotatable crankshaft (20) being driven by combustions in combustion chambers (12, 14) of said cylinders, wherein a pressure in each of said combustion chambers (12, 14) is measured and an amount of torque produced by each of said cylinders is determined based on the pressure measurements, wherein further the pressure is measured intermittently in sample steps (j), thus generating pressure sample value (p j ) for each sample step (j) determining a value (V' j ) of a change of the cylinder's combustion chamber volume for each sample step and a torque value (T) each cylinder produces during a certain rotation angle (Δα) of the crankshaft (20) is calculated by multiplying each pressure sample value with the respective volume change value and by summing up all such obtained products and multiplying the result of the sum by Δα/4π.

摘要： It is described a method for adapting injector characteristics of fuel injectors (30, 32) of a multi-cylinder internal combustion engine (10) having combustion chambers (12, 14) with direct fuel injection, which injector characteristics are adapted for each injector (30) individually to compensate for deviations the individual injectors (30, 32) have from standard injectors (30), wherein fuel is injected by each injector (30) and the operation of the engine resulting therefrom is evaluated, and wherein the method further comprises: determining for each cylinder a value of the peak pressure or the indicated mean pressure, which pressure value occurs during a combustion cycle in the cylinder's combustion chamber (12, 14), and modifying the injector characteristics individually for each injector (30, 32) to minimize differences between the pressure values over said cylinders.

摘要： A method for controlling an automotive internal combustion engine (1) having direct fuel injection is described, the method comprising a fuel adaption part in which a fuel quality parameter (F) is determined using a first fuel quality parameter determination procedure under predetermined conditions, and a control part which uses the value of a fuel combustion characteristics parameter (MFB50) derived from the fuel quality parameter (F) as a target value (αT) in a closed-loop control of the start of injection (SOl) at the engine (1), with the closed-loop control using a second fuel quality parameter determination procedure being different from the first fuel quality parameter determination procedure to determine an actual value (αA) of the fuel combustion characteristics parameter (MFB50).
