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 (e.g., a method for controlling and/or operating a compressor) are provided that includes the steps of monitoring a crankcase pressure of a first compressor; analyzing the monitored crankcase pressure that includes calculating an average of the crankcase pressure over a time period and comparing the average of the crankcase pressure over the time period to a nominal crankcase average pressure; identifying a condition of the first compressor based on the analysis of the monitored crankcase pressure; and adjusting operation of a second compressor to compensate for the first compressor in response to identifying the condition of the first compressor based on the analysis of the monitored crankcase pressure. (The method may be carried out automatically or otherwise by a controller.)

Abstract: In one aspect, a method for detecting and diagnosing a coolant leak of an engine may include diagnosing a coolant leak of the engine based on a low frequency pressure response of a measured engine coolant pressure. In another aspect, an engine system (e.g., for a vehicle) includes an engine and a coolant system operatively connected to the engine. The coolant system includes a coolant reserve and a coolant pump between the engine and the coolant reserve. The engine system also includes a coolant pressure sensor to measure coolant pressure, and a controller configured to measure an engine coolant pressure and diagnose a coolant leak of the coolant system based on a low frequency pressure response of the measured engine coolant pressure.

Abstract: Systems and methods of the invention relate to monitoring a change in a rotational speed of a crankshaft to identify a failure related to a crankcase breather valve. A reciprocating compressor can include a detection component that is configured to track a rotational speed of a crankshaft of a compressor to identify a change in rotational speed. In an embodiment, the rotational speed can be monitored while unloaded and/or below approximately 800 Revolutions Per Minute (RPM). Based on a change in a rotational speed of the crankshaft, a controller can be configured to communicate an alert which corresponds to a failure related to the crankcase breather valve.

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.
