Goals and Guidelines: Rankine Cycle Propulsion Systems for Application to Urban Buses and Other Heavy-Duty Vehicles.

摘要

Preliminary goals and guidelines are presented for the development of low-emission Rankine Cycle Engine (RCE) external combustion propulsion systems for urban transit vehicles. Both interim and long-range goals for power systems are described,so that development can progress toward prototypes having properties acceptable to fleet operations. The general guidelines cover only RCE power plants,although guidelines for other external combustion systems are recommended. Principal areas covered in the report include: (1) a description of the bus and its characteristics; (2) general power system requirements; (3) performance criteria; (4) fuels and fuel economy; (5) objectives for reduction of emissions,noise,and heat release; (6) operational safety; (7) operating characteristics; (8) reliability and maintenance factors; (9) resources and materials utilization; (10) production consideration; (11) cost projections;and (12) applications.
