METHOD, COMPUTER PROGRAMME AND CONTROL AND/OR REGULATION DEVICE FOR OPERATING AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for operating an internal combustion engine (10), in particular on a motor vehicle, whereby fuel is introduced under pressure by means of at least one injection valve (18). The injected amount of fuel is influenced by the injection time of the injection valve (18). According to the invention, an optimal operating standard and a good component security may be achieved even with a faulty fuel pressure (pr) whereby a maximum permitted torque and the current torque (mimxth) for the internal combustion engine (10), which is dependent upon the fuel pressure (pr) are determined.
