Dual mode diesel electric power system for vehicles

摘要: A diesel-electric propulsion and operating system may be used alone or in combination with another power supply. It has particular application to a dual mode, trolley diesel bus. The engine is controlled supply only that demanded by the electrical systems, including traction motor, operate on fixed curve. This provides an optimized efficiency. Other novel characteristics include two-speed drive axle limited mode selector, backup hydraulic motor pump, passenger compartment tester, pretester.
