In this research the new engine (ZEE) for automotive, different types of it and also the governing thermodynamics cycle has introduced, then there's comparison is expressed between thisengine and the conventional ones which apply in automotive engine to reduce pollutants resulting from combustion and why this engine design. In this step super critical thermodynamics cycle of the ZEE03 engine is studied The next step, combustion in the porous burner and the relevant advantages of it has beenreviewed. At this point review of materials used in the porous burner, various structures of it and finally numerical simulation of combustion in two-stage porous burner and solve governing equations on fluid in porous media has been done With regards to effects of the correct locating of the input and output valves, opening and closing time of them and geometry of the cylinder and piston in the both engine efficiency and performance of thermodynamics cycle, therefore in thethird step, two-dimensional simulation of fluid motion in cylinder chamber has been paid with fluent softwar Key words : Porous Medium, Combustion,Radiation,Steam Engine, Porous Burner, Effective Conduction Heat Transfer Coefficient
