基于内燃兰金循环的二氧化碳回收车用动力系统

CO_2 capture automotive engine system based on internal combustion ranking cycle

模拟计算了内燃兰金循环(ICRC)的热效率,并对ICRC动力系统在大型公交车上的使用成本进行了估算。结果表明,通过在上止点附近向缸内喷水有效回收了废热,内燃兰金循环的循环热效率高达55.6%,可显著提高发动机的燃油经济性。ICRC动力系统使用成本比柴油动力系统低6%,且无有害气体及温室气体排放,具有广阔的市场前景。

This paper investigates the thermal efficiency of Internal Combustion Ranking Cycle （ICRC） by simulation. The operating cost of the use of ICRC in large public transport bus is also evaluated. Results show that the thermal efficiency of ICRC can be achieved as high as 55.6%, and the operating cost of ICRC is reduced by 6% in comparison with conventional diesel engine. The ICRC engine has potential future market because of its excellent emission performance accompanying with affordable CO2 capturing technology.
