Abstract
A system for detecting conditions indicative of substandard performance of cylinders in a diesel engine includes an engine control unit disposed in operable communication with the engine and a computer disposed in informational communication with the engine control unit. The engine control unit is in operable communication with the engine through a communication element. The system measures the required fuel with all cylinders operating and enables a recommendation to be made with respect to corrective or maintenance measures that should be undertaken with respect to the cylinder. A method for utilizing the system includes comparing fuel requirements of the engine operating under power of all cylinders and under the successive arrest of each of the cylinders. The process is repeated until each cylinder is individually removed and all of the data can be compiled and considered to determine the performance of each individual cylinder.
