Aspects of the disclosure present a cooler driven by an engine turning a generator wherein the engine and the cooler are not linked by a direct drive shaft.

This generator set is provided with an airflow path which has an air inlet and an air outlet and through which a cooling air flows, a power generator, an alternator which is driven by the power generator, and a radiator which is installed in the airflow path, with a cooling medium circulating between the power generator and the radiator, wherein the inflow area of the cooling airflow into the radiator is greater than the passage area of the air inlet.

Various embodiments of the present disclosure are directed towards free-piston combustion engines. As described herein, a driver section may be provided in a free-piston combustion engine for storing energy during an expansion stroke. The driver section may be configured to store sufficient energy to perform the subsequent stroke. In some embodiments, the driver section may be configured to store sufficient energy so as to enable the engine to operate continuously across engine cycles without electrical energy input. A linear electromagnetic machine may be provided in a free-piston combustion engine for converting the kinetic energy of a piston assembly into electrical energy.

A system and method monitor operation of a compressor, determine whether the operation of the compressor is outside of a designated range of values, and, responsive to determining that the operation of the compressor is outside of the designated range of values, one or more of (a) prevent communication of a signal to a system controller that controls operation of the compressor, (b) direct a gas from a reservoir to a pressure sensor used by the system controller to determine a gas pressure generated by the compressor, and/or (c) communicate the signal to the system controller that controls operation of the compressor.

An enclosure for a genset comprises a container defining an internal volume for housing the genset. The container comprises a container floor, a container roof, a pair of container sidewalls disposed parallel to a longitudinal axis of the container, and a pair of container endwalls disposed at longitudinal ends of the container. A side cap is positioned parallel to each of the pair of container sidewalls along a longitudinal length of the container, each of the side caps sealed to edges of the corresponding container sidewall so as to define an acoustic cavity therebetween.

A vehicle drive includes a speed change mechanism connected to a rotary electric machine; an output member connected to the speed change mechanism and wheels; an engagement device changes a state of engagement between an input member connected to an engine and the speed change mechanism; a hydraulic pump driven by the engine or the rotary electric machine; a first pressure control device that controls pressure supplied from the pump and supplies the pressure to the speed change mechanism; a second, separate hydraulic pressure control device that controls the pressure supplied from the pump and supplies the pressure to the engagement device; and a case that houses the rotary electric machine, speed change mechanism, engagement device, and pump. At least the engagement device is housed in a space formed by the case, and the second hydraulic pressure control device is provided at a part of the case forming the space.

An integrated mobile ground support system 10 includes a wheeled cart 12 on which is mounted a power plant 14 to power an air compressor 16 to provide bleed air to an aircraft. The power plant 14 also powers an electrical generator 22, the output of which is controlled and converted to AC and/or DC power to meet the power requirements of the aircraft. An air conditioning unit 20 is also mounted on the cart 12 for providing conditioned air to the aircraft.

A generator module includes a housing arranged for mounting to a rear face of an internal combustion engine, a generator stator fixed in the housing, a generator rotor arranged radially inside of the generator stator, and a bearing arranged to support a radial inside of the generator rotor on the housing. The generator rotor may include a rotor carrier and a plurality of stacked plates secured to the rotor carrier. The bearing may be at least partially radially aligned with the plurality of stacked plates.
