A diesel generator with an improved load capacity according to one embodiment may include a generator body including a field magnet and an armature, and configured to convert rotational energy of a diesel engine main body into electric energy; and an automatic voltage regulator configured to control power supplied to a field winding and to control output voltage of the generator body. The automatic voltage regulator is driven by a power supplier configured to supply constant voltage or current based on power storage and conversion. According to the present disclosure, the diesel generator may have a load capacity without a PMG.

A work machine that can discharge water collected inside a casing to the outside, reduce leakage of noise, and reduce entry of foreign matter from outside. The work machine includes a bottom portion cover forming a portion of a casing, and the bottom portion cover includes: at least two ribs and a bead (strengthening structure portions) that are formed substantially perpendicular to a bottom surface of the bottom portion cover; and a drain hole located in a connecting portion connecting the bottom surface of the bottom portion cover and a water-discharging rib among the at least two ribs. An upper portion of the water-discharging rib is located over the drain hole.

Disclosed example power systems include an enclosure, an engine within the enclosure; and a generator within the enclosure and configured to convert mechanical power from the engine to electrical power. The enclosure includes a first air inlet on a first end of the enclosure, a first air outlet on a top of the enclosure, and a second air inlet on a side of the enclosure to provide a second airflow through the enclosure. The power system further includes an engine fan configured to generate a first airflow from the first air inlet to the first air outlet to cool the engine. The power system includes a diverter located below the first air outlet and configured to direct environmental contaminants away from at least one of the engine or the generator, where the environmental contaminants enter the enclosure through the first air outlet.

An enclosure assembly is provided to house an engine of a generator set system. The enclosure assembly includes an enclosure having a plurality of walls. The engine is disposed in an interior space defined by the plurality of walls. A chamber disposed in the interior space of the enclosure includes a vent port in fluid communication with an exterior of the enclosure and an intake port for communication with an intake of the engine. In one example, the chamber is closed from fluid communication with the interior space of the enclosure.

A generator enclosure for an engine-generator includes multiple walls defining at least one air path. In one example, a first wall includes an exhaust path for the engine-generator, and a second wall includes an intake path for the engine-generator. The generator enclosure may include at least one air flow frame associated with the exhaust path or the intake path and at least one movable wall supported by the at least one air flow frame, At least one thermal fuse may be coupled to the at least one movable wall and configured to release the at least one movable wall to block the exhaust path or the intake path.

A sound-attenuated power generation system includes an enclosure. The enclosure includes a floor, side walls, end walls, and a roof. The system includes sound damping foam panels mechanically coupled to the interior of at least one of the floor, side walls, end walls, and roof. The enclosure has an intake vent formed in the side wall; an exhaust vent formed in the side wall; and a generator positioned within the enclosure, the generator including an engine.

Systems and apparatuses include an asynchronous electrical machine coupled to an engine, a power supply selectively coupled to the electrical machine by a power supply switch device, and an electrical output coupled to the electrical machine by an output switch device. The electrical machine is structured to produce electricity when the power supply switch device is open, the output switch device is closed, and the electrical machine is mechanically driven by the engine, or perform as a starter motor to start the engine when the power supply switch device is closed, the output switch device is open, and the electrical machine mechanically drives the engine.

An autonomous modular device for an electric generating plant is described which may be in the form of a container that makes use of a vehicular engine adjacent to the canopy of a modular structure. A drycooler heat exchanger, with a layout different from the other existing layouts, implying improvements in the use of this type of autonomous generator system, is provided insofar as it provides easy transport, adequate consumption without mechanical loss and high energy efficiency. In one embodiment the vehicular engine is placed under the canopy of the modular structure, wherein a drycooler heat exchanger is accommodated, and not an engine radiator, with a different arrangement from the other existing units. A second embodiment is adapted to places where there is no physical space for the model including the heat exchanger under the canopy, forcing the installation on the ceiling of the installation, or for other installations.

A frameless cooling module includes a first and a second shroud panel arranged at opposing sides of the module and extending from the front of the module to the back of the module. At least one L-shaped stiffener bracket extends between the panels at an intermediate location along both the height direction and the depth direction of the module. One or more heat exchangers is arranged within the cooling module between the L-shaped stiffener bracket and the front of the module, and is at least partially secured within the cooling module by being mounted to the L-shaped stiffener bracket.

A plenum for processing one or more byproducts output from a generator, and systems and methods thereof, can have the plenum in the form of a hollow elongate rectangular box having a first end and a second end opposite the first end. The plenum can have a frame and a sidewall fixed to the frame, and can be adapted to be oriented vertically when operatively coupled to receive the one or more byproducts from the generator. The sidewall can include an opening adapted to receive heated air from the generator as one of the byproducts from the generator.
