TL;DR: In this article, the stator is arranged so as to encircle the rotor and to be encircled by an air induction casing, and a cooling fan of a centrifugal blower type is located at the upper end of the rotor shaft with the blades thereof directed to the side of the generator.
Abstract: In an engine generator having a work generator arranged at the upper side of an engine of a vertical crank shaft type, the output shaft of the engine projects upwards from the engine crank case so as to be connected to the rotor of the work generator. And the stator is arranged so as to encircle the rotor and to be encircled by an air induction casing. A cooling fan of a centrifugal blower type is located at the upper end of the rotor shaft with the blades thereof directed to the side of the generator so as to supply a cooling air flowing upwards to both the interior and the exterior of the stator during operation.
TL;DR: A surface cooler comprises a plate-like layer and a plurality of spaced-apart fins extending substantially perpendicular from an uppermost layer of the platelike layer as discussed by the authors, which are configured to augment heat transfer of the surface cooler by increasing the turbulence levels of a fluid flowing through the airflow paths.
Abstract: A surface cooler comprises a plate-like layer and a plurality of spaced-apart fins extending substantially perpendicular from an uppermost layer of the plate-like layer. The plurality of fins defining a plurality of air flow paths. The plurality of spaced-apart fins are configured to augment heat transfer of the surface cooler by increasing the turbulence levels of a fluid flowing through the airflow paths by promoting increased mixing with a resulting increase in the heat transfer coefficient of the surface cooler. A method of forming the surface cooler and an engine including the surface cooler.
TL;DR: In this article, a methodology for the estimation of the mean temperature of the cylinder inner surface in an air-cooled internal combustion engine is proposed, which avoids the use of data or correlations developed for other engines, providing more reliable results than extrapolating models from one engine to another.
TL;DR: In this article, the static cover is configured to prevent user access to a moving component of an air-cooled internal combustion engine, including an engine block, a blower assembly, and a static cover.
Abstract: An air-cooled internal combustion engine includes an engine block, a blower assembly including a blower housing and a fan, and a static cover. The static cover includes multiple air intake openings and is configured to prevent user access to a moving component of the engine. The blower housing is configured to at least partially direct air to the engine block. The fan is configured to move air into the blower assembly through the air intake openings when rotating in a first direction in a cooling mode and to move air out of the blower assembly through the air intake openings when rotating in an opposite second direction in a debris-removal mode.
