An apparatus and method for establishing parallel flow to and from a plurality of turbochargers operating in parallel. The turbochargers are mounted on a manifold that has a high pressure chamber and a low pressure chamber. A plurality of turbines are mounted to the manifold so that each turbine inlet is in communication with the high pressure chamber and each turbine outlet is in communication with the low pressure chamber. Each turbine inlet is sized, shaped and positioned to accommodate a designed proportional mass flow rate to each corresponding turbine. A programmed logic controller and suitable control valve can be used to bypass a portion of the engine exhaust gas from the high pressure chamber directly to the low pressure chamber. The amount of bypassed engine exhaust gas can be controlled to vary the power output of turbines.

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.

Systems and methods of the invention may overcome a higher than normal starting torque for in a reciprocating, electric motor driven air compressor for a vehicle. A detection component can be configured to detect a stall condition for a reciprocating compressor based on a force from compressed air being compressed into a reservoir of the reciprocating compressor. Based upon the detected stall condition, a controller can reverse direction or increase torque to alleviate the stall condition. In the reverse direction mode, the controller component can change a direction of a piston rotation. In the torque increase mode, the controller increases a number of poles for the motor, a line voltage, or a volt/hertz.

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 approximiately 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.

A combination compressor unloader which has a horizontal cylinder and a double acting piston forming two compression chambers. Each chamber communicates by a passageway with a supplementary chamber with each passageway associated with a reversible actuator having an attached unloader plug capable of sealing the passageway from a remote control. A second means is provided to form a reversible by pass that can deactivate at least one cylinder end of said double ended piston.

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.

Systems and methods of the invention relate to diagnosing a compressor. A method may include monitoring a crankcase pressure of a compressor, analyzing the monitored crankcase pressure, and identifying a condition of the compressor based on the analysis of the monitored crankcase pressure. A system is also disclosed including an engine, a compressor operatively connected to the engine, and a controller that is operable to identify a condition of the compressor.

Systems and methods of the invention relate to removing fluid from a compressor to mitigate condensation accumulated for a compressor. A controller can be configured to actuate a drain valve coupled to an aftercooler of a compressor and actuate a check valve to isolate air pressure of the aftercooler from a reservoir of the compressor. Through control of the drain valve of the aftercooler and the check valve, the controller removes fluid from the aftercooler to facitliate thermal management of a compressor.
