Abstract

An engine generator includes an engine having an intake device and an exhaust device which are connected to an engine body, a generator connected to the engine, and a fuel tank for supplying fuel to the engine. The engine, the generator and the fuel tank are mounted on a frame. In this engine generator, the intake device and the exhaust device are connected to an upper portion of the engine body having a cylinder axis extending vertically to protrude to opposite sides from the engine body, and the fuel tank is disposed sideways of the engine body and the generator below the intake device or the exhaust device. Thus, when a vertical engine is used, the fuel tank can be effectively disposed to avoid the production of a wasteful space, thereby providing reductions in size, weight and cost.

Claims

1. An engine generator comprising:

an engine including an intake device and an exhaust device which are connected to an engine body;

a generator connected to said engine; and

a fuel tank to supply fuel to said engine;

wherein said engine, said generator and said fuel tank are mounted on a frame, and wherein said intake device and said exhaust device are connected to an upper portion of said engine body having a vertical cylinder axis extending therefrom such that said intake and exhaust devices each protrude from opposite sides of said engine body, and said fuel tank is disposed to extend along and to the side of both said engine body and said generator, said fuel tank having a longitudinal axis parallel to an axial direction of a crankshaft of the engine body, said fuel tank located below one of either said intake device and said exhaust device.

2. An engine generator according to claim 1, further including a guard member which is secured to said frame to cover a side of said fuel tank on the opposite side from said engine body and said generator, said fuel tank being fixedly supported on said guard member.

3. An engine generator according to claim 2, further including an elastomeric member attached to said frame for receiving a bottom of said fuel tank.

4. An engine generator according to claim 2, further including a control panel having a plug socket for taking out an electric power from said generator, said control panel being mounted on said guard member.

5. An engine generator according to claim 1, further including a pipe line connected to a bottom of said fuel tank for guiding fuel, and a lower guard plate secured to cover a connection portion of said pipe line and said fuel tank from below.
