Abstract
An engine and power units employing the engine are provided which include a crankshaft oriented vertically and operatively connected to the engine, a liquid-cooled radiator arranged above the engine substantially perpendicular to the crankshaft, and a cooling fan interposed between the engine and the radiator and operatively connected to the crankshaft. The engines and power units may be employed in motor vehicles and other equipment such as electrical generators.
Claims26
A power unit comprising:
- an engine;
- a vertically oriented crankshaft operatively connected to said engine;
