Influences of Mixture Composition on Waste Heat Recovery System for Vehicle Internal Combustion Engine
Translated Abstract
The exhaust energy of 280 kW vehicle internal combustion engine in the whole conditions was analyzed by the ex-periment .A set of organic Rankine cycle system was designed and its working performance was analyzed under different engine operating conditions .Based on R245fa dry substance and R152a wet substance ,three zeotropic mixtures were prepared .The influence of zeotropic mixtures with different composition on the organic Rankine cycle waste heat recovery system performance was investigated .The results showed that the net power output ,waste heat recovery efficiency and required zerotropic mixture mass flow of organic Rankine cycle system increased gradually with the increase of engine speed and torque .The performance of zeotropic mixture containing the highest content of R152a was optimal .
