Abstract

A test kit is disclosed for testing an internal combustion engine with the engine kept at a fixed load condition. The test kit includes a test module programmed to execute a sequence of individual cylinder tests by measuring, in each cylinder test, a first engine performance value and providing an amount of fuel to one cylinder under test to differ from an amount of fuel provided to the rest of the plurality of cylinders. A further test module is programmed to measure, in an idle period between subsequent individual cylinder tests of the sequence of individual cylinder tests, a second engine performance value. This further test module is programmed to discard at least some of the individual cylinder tests if the second engine performance value measured by the further test module passes a threshold.
