Abstract: Systems and methods of the invention relate to diagnosing a compressor. A method may include monitoring a pressure of compressed air within a reservoir, actuating a piston within a cylinder of the compressor, and detecting a leak condition of an exhaust valve of the cylinder through recognition of a change in the monitored pressure of the compressed air within the reservoir during a time period in which the piston is actuated. A system is also disclosed including an engine, a compressor operatively connected to the engine, and a controller that is operable to determine a condition of the compressor.

Abstract: Systems and methods of the invention relate to diagnosing a compressor. A method may include monitoring a pressure of compressed air within a reservoir of a compressor, actuating an unloader valve of the compressor, and detecting a leak condition of the compressor through recognition of a change in the monitored pressure of the compressed air within the reservoir during a time period in which the unloader valve is actuated. A system is also disclosed including an engine, a compressor operatively connected to the engine, and a controller that is operable to determine a condition of the compressor.

Abstract: Systems and methods of the invention relate to diagnosing a compressor. A method may include operating a compressor to compress air from a first stage compressor into an intermediate stage reservoir, to deliver air from the intermediate stage reservoir to a second stage compressor, and to further compress the air in the second stage compressor into a primary reservoir, monitoring an intermediate stage pressure of the intermediate stage reservoir, and identifying a condition of the compressor through recognition of a change in the monitored intermediate stage pressure during a time period in which the compressor is operated. A vehicle system is also provided including an engine, a compressor operatively connected to the engine, and a controller that is operable to identify a condition of the compressor.
