Abstract: A oil supply system supplies the same oil for lubricating an engine and for driving a hydrostatic infinitely variable transmission. The hydrostatic infinitely variable transmission is built into a crankcase of the engine, resulting in an overall compact configuration. A drive shaft of the hydrostatic infinitely variable transmission is provided parallel with a crankshaft of the engine. Axial centers of the drive shaft and crankshaft can be made hollow and serve as oilways. Further, an axial center of a counter shaft of the hydrostatic infinitely variable transmission can be made hollow and serve as an oilway. By the present oil supply system, engine oil is used in common as drive oil for the hydro-static infinitely variable transmission, and as oil supplied to parts of a cylinder head, a stepped transmission, and other various parts of the engine and transmission, thereby elimating the duplication of oil pumps and filters and reducing the maintanance associated with servicing independent oil systems.

Abstract: Fuel injector apparatus is described, for use on internal combustion engines using slurry fuels, wherein a portion of the engine air mass is passed through an aspirator passage shortly prior to combustion and the slurry fuel is aspirated into this air portion. The thusly mixed air and fuel slurry is distributed throughout the engine combustion chamber via several exit channels from the aspirator. The fuel portion of the slurry is reduced to a very small size when the slurry is prepared, and fine atomization of the slurry during injection into the engine is not needed. Hence relatively low velocity slurry injection can be used and injector wear problems greatly reduced.
