LABORATORY AND ON-HIGHWAY TESTING OF DIESEL ORGANIC RANKINE COMPOUND LONG-HAUL VEHICLE ENGINE

An Organic Rankine-Cycle System (ORCS) designed for use with a 288-Bhp, Class 8, Long-Haul Vehicle Diesel Engine has undergone both laboratory endurance-performance testing and actual on-highway fuel economy comparison testing. Two, 1000-hour endurance tests have been conducted to demonstrate the functional integrity of the basic ORCS design and reveal any "infant mortality" problems with individual components. On-highway vehicle fuel economy tests demonstrated a statistical average of 12.5-percent improvement in fuel consumption. Such tests have been conducted in a project sponsored by the U.S. Department of Energy as part of their long-term national goals of improving the fuel consumption in energy-intensive industries, such as, but not restricted to, the U.S. Trucking Industry. Approximately 100,000 barrels of oil per day are expected to be saved with the full implementation of a Diesel Organic Rankine-Cycle Compound Engine in the U.S. Trucking Industry. A brief description of the basic ORCS components including the advanced microprocessor-based control system is included. The results of the laboratory endurance-performance and the on-highway vehicle tests will be given. A short discussion of the future work required in advancing the development of a commercial ORCS for long-haul vehicles is also given.
