摘要： The invention relates to supplying pilot fuel to the cylinders of a combustion engine. The invention comprises cylinder-specific pressure sensors (1) that are installed in the cylinders of the combustion engine, as well as a control unit (2). The control unit determines each cylinder's crankshaft angle at maximum pressure and the cylinders' average crankshaft angle at maximum pressure, and verifies whether the average crankshaft angle at maximum pressure is within a certain range of crankshaft angle variation. If the average crankshaft angle at maximum pressure is outside the range of variation, the duration of total pilot fuel injection into the engine is controlled. Furthermore, the differences between each cylinder's crankshaft angle at maximum pressure and the average crankshaft angle at maximum pressure are determined. The differences are compared with a certain range of difference variation, and the duration of fuel injection into a cylinder is controlled if the difference in an individual cylinder traverses the minimum or maximum limit of the range of difference variation.

摘要： The invention relates to balancing the cylinders of an internal combustion engine. The invention comprises cylinder-specific pressure sensors (1) installed in the cylinders of an internal combustion engine for measuring the cylinder pressures as well as an adjustment unit (2). The adjustment unit is arranged to determine the maximum pressure and knock value of each cylinder as well as the mean maximum pressure of the cylinders as a response to the measurements of cylinder pressures and to determine the differences between the maximum pressure of each cylinder and the mean maximum pressure. The differences are compared to a certain deviation range of the mean maximum pressure and the knock value to a certain knock limit value. The duration of the fuel injection of the cylinder is adjusted in case the difference of a single cylinder exceeds the lower limit of the deviation range and the knock value of the cylinder is less than the knock limit value or the difference of the cylinders exceeds the upper limit of the deviation range.

摘要： An an internal combustion engine has a plurality of cylinders for providing the necessary energy used for the work performed by the engine. Cylinder specific knock monitoring is used in order to distribute the load automatically among the cylinders of the engine. When an individual cylinder knocks continuously, the antiknock control system of the cylinder aims at reducing permanently the quantity of fuel supplied to the cylinder. The fall in the total output caused by the reduction of fuel supply is compensated by increasing the fuel supply to all cylinders. The new operating values of the engine provided by the adjustment are stored in the memory and used also as new reference values.
