Abstract
In recent years the scientific and public awareness of the environment and energy issues brought great interest for research of advanced technologies, particularly in the efficiency of internal combustion engines. Thus, many researchers study ways to achieve better efficiencies in a more sustainable manner through various technologies, among which is the recovery of heat. A six stroke engine is considered as one of these technologies, it uses heat from the exhaust gases and proposes the addition of an extra cycle power carried by water injection. This work consists in undertaking an exergy analysis of a six stroke engine with water injection for comparisons to be made with conventional four strokes engine. Increases were observed in the exergetic efficiency of up to 14 % for different amounts of water injected at different injection temperatures for the six stroke engine. It was also noted a decrease of about 20% in lost exergy by the engine, a fact that proves the best use of exergy released by the fuel. The six stroke engine thermodynamic analysis shows that this technology has significant potential to achieve a better use of fuel and therefore achieve better efficiencies.
