Description/Abstract This paper describes a method for improving the performance of a multi-cylindered internal combustion engine having fuel injection by injectors controlled by an electronic controller, with the cylinders having internal thermodynamic operating values.^It comprises: with electronic thermodynamic value transducers, sensing the operating values inside the individual cylinders of the engine; with the electronic controller connected to the transducers, comparing the various thermodynamic operating values within the various cylinders to a standard thermodynamic value; and controlling the injectors such that cylinders operating at least a minimum amount below the standard thermodynamic value receive more fuel, thus elevating the thermodynamic operating value in the respective cylinder, and cylinders operating at values at least a minimum amount above the standard thermodynamic value receive relatively less fuel, such that thermodynamic operating values in the individual cylinders of the engine tend toward the standard thermodynamic value.
