Engine driven generator assembly
First Claim
1. An internal combustion engine driven generator assembly, comprising:
- a thermally and acoustically insulated housing including a substantially rigid frame to which insulation elements are attached, said frame and insulation elements constituting housing walls;
a generator mounted in said housing, said generator having a substantially horizontal generator shaft;
an internal combustion engine mounted in said housing substantially vertically over said generator, said engine having a substantiall horizontal crankshaft situated substantially in the same vertical plane in which said generator shaft is situated;
said generator and engine being suspended from said housing frame;
a fuel tank for said engine, said fuel tank constituting at least a part of a wall of said housing for providing lateral stiffening reinforcement therefor;
an intake air port, an exhaust air port and an aperture adapted to receive an exhaust pipe, said air ports and exhaust pipe aperture being provided in a common housing wall, said intake air port being situated below said exhaust air port and said exhaust air port being situated below said exhaust pipe aperture; and
a ventilation module adapted to be mounted in said common housing wall in which said air ports and exhaust pipe aperture are formed, said ventilation module including apertures formed therein through which intake and exhaust air ar adapted to pass respectively, louver means for opening and closing said apertures, and a fitting for connection to an exhaust pipe mounted in said exhaust pipe aperture.

Abstract
An engine driven generator assembly comprises an internal combustion engine, e.g. a diesel engine and a generator driven by the engine, the engine and generator being mounted in a thermally and acoustically insulated housing provided with ports for cooling intake air and exhaust air and an aperture for an exhaust pipe. The engine is mounted in the housing substantially vertically over the generator, the engine having a substantially horizontal crankshaft which is situated substantially in the same vertical plane in which a substantially horizontal generator shaft is situated. A fuel tank for the engine is provided which constitutes at least a part of a wall of the housing to provide lateral stiffening reinforcement therefore. The ports for cooling intake air and exhaust air as well as the aperture for the exhaust pipe are provided in a common housing wall with the intake air port situated below the exhaust air port which in turn is situated below the aperture for receiving the exhaust pipe. A ventilation module is mounted on the common housing wall in which the air ports and exhaust pipe aperture are provided, the ventilation module including apertures formed therein through which intake and exhaust air are adapted to pass. Louvers are provided in the ventilation module for opening and closing the apertures and a fitting is provided for connection to the exhaust pipe received in the exhaust pipe aperture. This construction provides a compact, space efficient assembly by which the noise generated during operation is significantly reduced.
