ComVEC High Efficiency Session - Oral Only Session
(Session Code: CVHE)


The need to identify and implement cost-effective technologies capable of delivering quantifiable improvements in vehicle efficiency is a top priority for the entire heavy duty vehicle continuum. Topics being invited include: IC Engine Technologies, Hybrids (both electric and hydraulic), Whole-Vehicle Technologies (electrification, cooling systems, low rolling resistance tires, aerodynamics, etc.) and Intelligent Transportation Systems.

Roots Expander Organic Rankine Cycle Exhaust Energy Recovery System for Heavy Duty Diesel Engines
For most Heavy Duty (HD) diesel engines over 50% of total fuel energy is lost to the ambient as heat (exhaust and coolant). Eaton Roots (Supercharger) technology has been used as expander (Roots Expander to demonstrate an efficient Organic Rankine Cycle (ORC) Waste Heat Recovery (WHR) system for a HD diesel engine. The present work includes a baseline engine characterization to identify and quantify the potential waste energy sources and correlate the thermodynamic models. Thermodynamic models were used to assess the merits of various WHR layouts and WHR components on system performance. An average of 6% fuel economy improvement has been predicted for Eaton Supercharger based expander in an ORC WHR system with ethanol as a working fluid for HD diesel engines
