Described is a power system having an engine, a generator, a belt-driven component, a first pulley, a second pulley, a third pulley, and a fourth pulley. The engine outputs a rotational force at a first rotational speed to rotate the first pulley. The generator converts mechanical power driving the generator shaft to electric power. The second pulley is drivingly coupled to the first pulley via a first belt and configured to rotate the generator shaft at a second rotational speed based on the first rotational speed. The fourth pulley coupled to the generator shaft having a first diameter that is greater than a second diameter of the second pulley. The fourth pulley configured to drive the third pulley at a third rotational speed to drive the belt-driven component

A mobile ground power unit includes a housing in which an engine and an electric generator are disposed. The housing features a canopy having an outer wall facing outside. The outer wall has a single piece covering an upper side of the engine and extending downwards along at least two different vertical sides of the ground power unit. The canopy has an inner wall facing inside. The inner wall features a horizontal area covering the upper side of the engine and is extending from the horizontal area downwards along the at least two different vertical sides. The inner wall and the outer wall define a hollow space between each other. The canopy has an integrated ducting system with an inlet opening within the outer wall of the canopy, whereby the hollow space constitutes an air channel for exchanging fluid between the inside and the outside of the housing.

A standby generator includes a standby generator enclosure having a partition wall separating a first end from an opposite second end of the enclosure, one or more airflow openings, and a first air duct and a second air duct each coupled to at least one of the one or more airflow openings. An engine mounts in the enclosure toward the first end from the partition wall, and an alternator driven by the engine mounts in the enclosure toward the second end from the partition wall. The engine includes an engine cooling fan that faces the first end to drive engine cooling air received from the first air duct toward the first end, and the alternator includes an alternator cooling fan that faces the second end to drive alternator cooling air received from the second air duct toward the second end.

An engine assembly is provided that includes an engine having a crankshaft that is caused to rotate response to a firing of the engine, a backplate affixed to the engine and comprising one or more air flow passages formed therethrough, and an engine cooling fan operatively coupled to the crankshaft so as to be rotated by the crankshaft, the engine cooling fan coupled to the crankshaft on a side of the backplate opposite the engine. The engine assembly also includes a fan cover mounted over the engine cooling fan and secured to the backplate, the fan cover including an opening through which an air flow is provided to the engine cooling. The backplate and the fan cover collectively form an air guide that directs a flow of cooling air generated by the engine cooling fan through the one or more air flow passages of the backplate and to the engine.

An energy process handling system may include energy process handling modules. Each module may be modularly and operationally engaged with at least one other module of the system, such that each module is inter-operationally engaged with the other modules of the system. The system may include at least one system energy process delivery outlet to a localized environment and at least one system energy inlet.

In a cogeneration device, a space is formed on a base member that supports an engine and an electric power generator in order to store leakages from the engine in the space. A panel-fixing bracket is provided outside the storage space, at a predetermined distance from a vertical wall section forming a vertical wall of the storage space. A panel, which is a part of a package, is bolted and fixed to the bracket. This structure enables each panel to be fixed to the base member while preventing the leakages stored in the storage space from leaking out.

Provided is an engine generator with improved accessibility to an operation panel. An engine generator includes: a casing; a generator; and an engine that drives the generator, the generator and the engine being housed in the casing, wherein a plurality of panels each having a predetermined dimension are respectively removably provided at side surfaces of the casing, and any selected one of the plurality of panels can be exchanged for a console for the engine generator.

A system for generating electrical power includes engine generators positioned on a pad and housed within an enclosure. The pad may have a first side having an associated long axis and a shorter second side having an associated short axis. The short axis is transverse to the long axis. The engine generators are electrically coupled to one another in a parallel fashion. Each engine generator includes a prime mover and an alternator that are serially aligned with the short axis of the pad. The enclosure encloses the engine generators and has a plurality of side walls, a roof, and a floor. The enclosure includes at least one intake opening formed in the floor to provide airflow into an interior of the enclosure.

A cooling air introduction path is formed in a base of a sound proof case of an engine-driven work machine. The base is divided into upper and lower portions, and a space in the upper portion is divided by a separation wall and arranged below an air discharging chamber. The upper part of one space is covered with a arranging plate, a partition wall is erected on the arranging plate, and a cooling air introduction port is provided between the partition wall and the separation wall to provide an engine chamber and one space are communicated, a hole is provided in the plate below the chamber, and one space and the space in the lower portion are communicated and located below the chamber. A cooling air intake port is provided on lateral walls of the lower portion to communicate the space inside the lower portion with the outside of the machine.

Power systems and enclosures having improved cooling air flow are disclosed. In some examples, a power system includes an enclosure, a first air inlet, a first air routing path, and a second air routing path. The first air inlet is at a first location on an exterior of the enclosure to permit intake of air from the exterior of the enclosure to an interior of the enclosure. The first air routing path is defined by the enclosure and directs air from the first air inlet through a welding-type power supply and a compressor. The second air routing path is separate from the first air routing path and defined by the enclosure. The second air routing path directs the air from the first air inlet or a second air inlet through at least one of an engine or a generator.
