Installation of a Diesel-Organic Rankine Compound Engine in a Class 8 Truck for a Single-Vehicle Test

A Class 8 truck has been equipped with a diesel-organic Rankine compound engine in preparation for a 1-year test program. The compound engine consists of an organic Rankine bottoming cycle system directly coupled to a Mack diesel engine from which it recovers the waste heat in the exhaust gases. The components of the bottoming cycle system are described, and their installations in three pre-assembled modules - a power conversion package, a vapor generator, and a cooling system - are discussed. Plans for the 1-year test program, including baseline performance tests on the compound engine, chassis dynamometer tests, noise tests, and over-the-road fuel economy measurements, are also outlined.
