A system for equalizing the performance among the cylinders of an internal combustion engine which involves the introduction of increased fuel to under-performing cylinders, and reduced fuel to over-performing cylinders, with the result that the cylinders all perform at a more uniform level. In the first embodiment, this is achieved by means of selecting unit injectors for a diesel engine according to the cranking compression in each cylinder so that cylinders with lower compression receive more fuel. In the second embodiment, in which injectors in either diesel or gasoline engines are controlled by an electronic controller, temperature sensors within the individual cylinders report to the electrical control unit which then operates the injectors to meter the fuel injection such that hotter operating cylinders receive less fuel and cooler cylinders receive more. The engine is then tuned according to the engine manufacturer\s standard procedures.

A method of improving the performance of a multi-cylindered diesel engine having unit injectors by tuning, comprising the following steps: (a) measuring the non-combustion compressions of a plurality of the cylinders of said diesel engine and noting the relative compressions of the cylinders relative to one another; and, (b) selecting and installing fuel injectors of differing flow rates, with the particular flow rate of each injector being so installed, being inversely related to the relative compression of the cylinder into which it is being installed, such that cylinders having relatively low compression are fitted with injectors having relatively high flow rates and vice-versa.
