Latest Patents

Ueda’s listed inventions address the design and integration of systems for V-type engines.

- **Cooling system for vehicle.** This invention describes an oil separator for a V-type engine’s crankcase ventilation system. Positioned in the valley between the cylinder banks, the separator uses a simplified arrangement to separate oil from ventilation gases.

- **Crankcase vent system.** This invention combines crankcase ventilation with engine cooling. A ventilation chamber sits in the valley of the V-shaped engine, while a main coolant gallery runs through the valley between the chamber and crankcase to cool ventilation gases. The gallery also partially encircles the main oil gallery to help cool the lubricant.
