Waste heat recovery (WHR) assessment in complete truck simulation environment

peer reviewedOrganic Rankine Cycle (ORC) based Waste Heat Recovery in long haul heavy duty (HD) trucks is a promising technology to reduce the fuel consumption. Despite several studies that have been conducted, such technology has not been introduced yet on the market. The constraints for a market introduction are related to driving cycle fuel efficiency, the integration of the WHR system in the truck, control of the system, material compatibility, weight and costs. This paper outlines the mentioned constraints and proposes a complete truck environment simulation study, considering interactions of the system with the other sub-systems of the truck. Control strategies and optimized Rankine energy utilisation are proposed to maximize the effectiveness of the system
