Abstract (en)
[origin: WO8906310A1] Control equipment for controlling the quantity of fuel supplied to the cylinders of an internal combustion engine by an injection device on each cylinder has a pre-control timing unit (10), an individual value store (11) and a logic element (12). The individual value store memorises individual values assigned to the injection devices for the individual cylinders of an internal combustion engine (13). The logic element combines the individual values with a pre-control time supplied by the pre-control timing unit to yield a control time for each injection device such that the lambda values measured by a lambda probe in the exhaust fumes are essentially the same for all cylinders. Good exhaust gas values can be obtained using this control equipment.
