Abstract (en)

[origin: DE10233778A1] The method involves determining part moments provided by the cylinders of the combustion engine. A cylinder coordination factor (FZGST,i) is formed for each cylinder. The hub of the injection valve allocated to the cylinder is corrected depending on the cylinder coordination factor. Each cylinder has an injection valve with variable hub. Independent claims are also provided for (1) Computer program for the compensation method (2) Control apparatus for combustion engine
