Résumé

Effective heavy-duty vehicle waste heat recovery using Organic Rankine cycle technology is a key solution toward meeting the increasing fuel economy while high cost along with a long payback period hinders its development. The re-architecture of gas heat exchange by coupling ORC and diesel engines is an effective technical route. This paper is targeted to propose a new heat exchange equipped with Diesel Particulate Filters and Diesel Oxidation Catalysts. The simulation model of the ORC and engine system including four-cylinder high-pressure common rail direct injection and exhaust post-treatment was established. Performance of ORC and species concentration of exhaust post-treatment were studied based on chemical dynamics. The results show that chemical reaction heat can effectively improve the thermal efficiency and output work of ORC. The efficiency increased from 11.26% to 15.8% and the output work increased from 5.63KW to 6.63KW due to the extra heat input.
