<p>The present invention provides an improved compound internal combustion engine designed efficiently from a thermodynamic standpoint. The present invention has improved fuel efficiency and emission control for both noxious gaseous outputs as well as emissions of carbon dioxide, a major constituent of greenhouse gases. On one aspect, the present invention comprises at least two chambers used in a multiple stage expansion design. Exhaust from the first chamber (302) is inlet for further expansion into the second chamber (304). A catalytic converter (318) is coupled to both chambers such that the exhaust gases from the first chamber are passed through the converter to undergo a catalytic process. The catalytic process serves to complete the combustion process from the first chamber, thereby cleaning the exhaust while increasing the heat content of the exhaust gases for further expansion.</p> |
