Abstract: A high efficiency and high output electrical generator sized to match the electrical demands of generating power for lighting and operation of large amperage electrical machinery including an improved gear belt drive designed to allow the a diesel engine to run at a lower rpm, resulting in optimal fuel conservation benefit and longer run time on a tank of fuel, the engine, generator and motor mounts form a uniquely unitized mounting system employing a modular bell housing and generator adaptor plate supporting the engine, gears, belt drive and generator components.
