Detection method of operating condition of cylinder of internal combustion engine, involves detecting temporal method of rotational speed of crankshaft and torque, produced in crankshaft of internal combustion engine

摘要

The method involves detecting a temporal method of a rotational speed of a crankshaft and a torque, produced in the crankshaft of an internal combustion engine (1). A small spraying distance of two partial injections of a cylinder, is detected, when the rotational speed of the crankshaft and the torque produced in the crankshaft, are increased. The detection of the spraying distance is performed by power stroke of the cylinder. The spraying distance between the injections of the cylinder, are expanded. Independent claims are also included for the following: (1) a control unit for a fuel injection system of the internal-combustion engine (2) a computer program (3) an internal-combustion engine.
