ABSTRACT:
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 and diesel bus. The diesel engine is controlled to supply only that power demanded by the electrical systems, including the traction motor, and to operate on a fixed power curve. This provides an optimized efficiency. Other novel characteristics include a two-speed drive axle limited to the mode selector, a backup hydraulic motor and pump, a dual mode passenger compartment tester, and a diesel engine pretester.
