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.

Abstract: A railroad locomotive includes traction motors for propelling the locomotive, and an isolation switch disposed in signal communication with at least one of the traction motors for isolating a faulting motor from the other traction motors.

Abstract: A multiple outlet centrifugal blower has an impeller that provides both radial and axial airflows that are independent of each other such that an obstruction in one of the airflow does not substantially affect the flow of the other. The blower typically includes a housing having an inlet port, first and second outlet ducts, and an impeller rotatably positioned and supported within the housing. The first outlet duct is configured to receive airflow in a radial direction with respect to the blades of the impeller, and the second outlet duct is configured to receive airflow in an axial direction with respect to the blades of the impeller.
