摘要: A hydrogen internal combustion engine (HICE) emits both heat and water from the combustion process. In this study, a new concept of recovery sub-system, which exploits water exhausted an automobile HICE as working fluid for steam power generation system based on Rankine cycle has been introduced. cycle, separated HICE exhaust is evaporated superheated by exhaust waste HICE, water vapor released to atmosphere after it used produce in expander. The operating proposed sub-system described along with its potential generated, its beneficence overall thermal efficiency HICE. The recovery evaluated various speeds using fundamental thermodynamic model analysis. Two designs have examined; one a condenser another without condenser. The results showed that design cost-effective simple approach, performance comparable another design. Both consumed almost equal amount their fluid. Consequently, concluded condenser preferable recovery sub-system could enhance from 27.2% 33.6%, representing improvements 2.9% 3.7% any recovery sub-systems at 1500 4500 rpm.
