A system, module, and method for generating reliable, high quality power on demand and off-grid includes a photovoltaic array for delivering DC power; a generator having a size ranging from about 5 kW to about 30 kW, and comprising an engine powered by hydrocarbon gas filtered through a coalescing filter and comprising an extended lubrication system; an uninterruptible power supply (UPS) comprising a storage battery, the UPS being coupled to the photovoltaic array for receiving the DC power, and to the generator by a bi-directional inverter for receiving, transmitting, and qualifying DC or AC power; and an intelligent controller coupled to the UPS for controlling output of the DC or AC power to at least one air compressor capable of providing compressed air to one or more pneumatic devices.

In an embodiment, an integrated ground support system for an aircraft is described herein, the system including a frame on which the system is arranged as a singular assembly. An engine, drive train, alternator, bleed air unit, one or more electrical components, and air cycle machine are mounted on the frame. The engine operates at a first operational state associated with a first rotational speed that is independent of a frequency associated with electrical power, if only the electrical power is to be used by the aircraft, and the engine operates at a second operational state associated with a second rotational speed, different from the first rotational speed, that is a function of a pressure associated with bleed air or the conditioned air, if the electrical power and one of the bleed air or the conditioned air are to be used simultaneously by the aircraft.

A thermal choke, includes (1) a body, comprising a heat conductive material, (2) an electric heater, on or in the body, (3) a temperature sensor, on or in the body, and (4) a fin, in a channel surrounded by the body. The thermal choke is configured to fit between a throttle assembly and a cylinder of a spark ignition engine.

Devices, systems, and methods to air cool a portable generator are disclosed. The devices include various air ducts to direct airflow over heated components within a cabinet of the portable generator to cool the components by convection. A damping fan draws ambient temperature air into the cabinet and directs the air into channels of an outflow duct.

An internal combustion engine-based system includes an internal combustion engine. The internal combustion engine-based system includes an engine interrupt connected to the engine. The engine interrupt is configured to selectively stop the operation of the engine. The internal combustion engine-based system includes a controller in communication with the engine interrupt. The internal combustion engine-based system includes a carbon monoxide detector in communication with the controller. The controller uses the engine interrupt to stop the operation of the engine when the carbon monoxide detector provides the controller with signals that are representative of a carbon monoxide level proximate the internal combustion engine that together form a trend of building carbon monoxide amounts over a set time interval.

A containerised generator set comprises a generator arranged within a container having a first aperture through which cooling air is exhausted in use. A pair of first doors are arranged to pivot outwardly on either side of the first aperture, with a removable wall being removably mounted between the first doors and spaced apart from the body of the container by the first doors from its lower end region to its tipper end region in its mounted position. The removable wall and the first doors define an exhaust air duct which preferably includes a sound absorbent material. The exhaust air duct extends for at least most of a total height of the body of the container to attenuate noise from the generator. Exhausted cooling air flows upwardly from the open upper end of the exhaust air duct and away from the immediate operating environment.

A container for a genset comprises a housing defining an internal volume. The housing includes a floor, a roof and a plurality of sidewalls at least one of which is movable relative to the roof and the floor between a first configuration in which the housing has a first width, and a second configuration in which the housing has a second width greater than the first width. The first width is not sufficient for a user to enter the internal volume of the housing for accessing a genset disposed within the housing, and the second width is sufficient for the user to enter the internal volume for accessing the genset. The first width can be the same as the width of an International Organization for Standardization 6346 container.

A generator assembly suitable for being carried on the back of a human comprising an internal combustion engine an alternator and a shaft driven by said engine and driving said alternator wherein when said generator assembly is being carried on the back of a human said shaft is substantially parallel to a longitudinal axis of said human. This enhances the manoeuvrability of the assembly. Preferably the assembly comprises a generator module having an engine and an alternator coupled directly by a common shaft, the generator module being attached to a frame of the assembly at only two longitudinally spaced-apart positions.

An engine-driven working machine capable of reducing an opening of an outer case to be small, and decreasing the number of components is provided. An engine-driven working machine 10 is a generator in which an inverter 27 is provided at a suction side of a cooling fan 17, and a fuel tank 25 is provided over the inverter 27. The generator 10 includes an intake port 36 that is formed in an outer case 12, and a first air guide passage 61 that is formed by a tank bottom portion 38 of the fuel tank 25. The intake port 36 is formed in a lower side part 12b of a tank front wall 37, in the outer case 12. The first air guide passage 61 is formed by the tank bottom portion 38 that is inclined with a falling gradient toward the inverter 27 from the intake port 36.
