Abstract: A system including an engine connectable to a time variant working load. A motor is connected to the engine, and a variable frequency drive is connected to the motor. A system controller is connected to the variable frequency drive, and is programmed to command the variable frequency drive to change a selected mode of the motor according to an operational state of the engine. An electrical generation mode includes the motor operating as a generation load on the engine when the working load falls to an intermediate load below the operational load. A generation load combined with the intermediate load includes about the operational load. A standby mode includes the motor operating as a standby load on the engine when the working load about equals the operational load. A drive mode includes the motor applying mechanical power to the engine.

Abstract: An anti-stall system to prevent an engine, particularly a low-powered engine, from stalling when encountering a load that the machine is capable of overcoming but due to the nature of the engine, the load encounter would result in a stall. The system includes a hydraulic system in communication with a control system that has one or more sensors that detect, determine, and/or transmit an operational variable. The control system further comprises a plurality of anti-stall blocks having unique configurations, including a first configured to limit output flow upon determination of an engine droop, a second configured to limit output flow based on available engine torque, a third configured to limit output pressure upon rapid engine droop detection, and a fourth configured to prioritize and share output flow between the machine functions. The anti-stall blocks provide for complementary and cooperative configuration to prevent a stall from occurring based on responses to the detection and determination of various dynamic and continuous operational variables in real-time or near real-time with operational parameters.

Abstract: An emissions evacuator system that collects natural gas vented from various components of a natural gas compressor system and directs the vented gases to the intake system of a natural gas engine of the compressor system. The evacuator system utilizes vacuum from an intake system of the natural gas engine contained on compressor packages to “suck up” the gaseous emissions from various emission sources on the compressor package. These emissions are rendered inert when combusted in the natural gas engine.

Abstract: Methods and systems to provide compressed air to one or more air consumers external to the engine via exhaust gases of an internal combustion engine are presented. In one example, the exhaust gas may be routed to drive an air turbine of an air compression system. The air compressed at the compression system may be stored in a tank and/or provided to the one or more air consumers.

Abstract: A hot water pressure washer employs an internal combustion engine with a drive shaft having an exhaust manifold fluidly connected to an exhaust water heat exchanger. The engine is driveably connected to a hydrodynamic heater, and a high-pressure pump for generating a stream of high-pressure fluid. The hot water pressure washer captures 80-90% of the thermal energy generated during combustion processes of the engine for heating water.
