Abstract

The present invention relates to a method for restricting work produced by combustion in a combustion chamber, wherein an aftertreatment system is arranged for reduction of at least one substance resulting from the combustion, wherein the work produced by the combustion is restricted when there is a malfunction regarding reduction of the at least one substance. The method includes: performing a first evaluation regarding the reduction of the at least one substance, when the first evaluation indicates a malfunction, performing a second evaluation regarding the reduction of the at least one substance, the second evaluation being different from the first evaluation, and restricting work produced by the combustion only when a malfunction regarding reduction of the at least one substance is indicated also by the second evaluation.
