11198039 · 2021-12-14 ·

A low emission submersible engine is part of a multipurpose aquatic device, such as an aquatic craft or an electrical generator. A propulsion system having a propeller is coupled to the submersible engine to produce a swimmer propulsion machine and a generator is attached to the engine to produce an electrical generator. The submersible engine receives air from a snorkel that extends up above a water line. The aquatic device has a fuel reservoir which may receive liquid fuel or may receive a fuel cylinder. Floatation chambers keep the aquatic device afloat with the engine submerged. The exhaust assembly and exhaust ports from the engine may also be submerged and the exhaust ports may provide additional thrust. A propulsion system housing integrates the drive shaft and propeller, clutch coupler, exhaust conduits and water flow conduits and is detachably attachable to the engine.

ENGINE

The engine includes a cylinder head provided over a cylinder row, an intercooler provided on one end side of the cylinder head in a row direction of the cylinder row, an air supply manifold to introduce air from the intercooler to the cylinder head, and a cooling piping connected to the intercooler, where the cylinder head, air supply manifold, and cooling piping are arranged in a width direction intersecting the row direction of the cylinder row in stated order of the cylinder head, air supply manifold, and cooling piping, and in a cross section of the air supply manifold taken along a line intersecting the row direction, a length along the width direction is shorter than a length along a direction intersecting both the row direction and the width direction.
