Abstract: This paper presents the outcome of innovative and creative research carried out regarding designing and analyzing a hybrid engine working by Compressed Air and gasoline. The conventional four strokes associated with IC Engines are being modified into six strokes. These tasks have been fulfilled by using UG NX-8, ANSYS CFD, SOLID EDGE-19 and MATLAB-2010.First four strokes of INCO are executed by the combustion process. Last two strokes are executed by Compressed Air. During the intake of fifth stroke, intake valve is open and only Compressed air enters the combustion chamber. During the exhaust (sixth stroke), exhaust valve opens and Compressed air exits through it. Prototype constructed has emphatically shown that it is possible to modify the conventional cycle to INCO cycle for the purpose of realizing the need identified for this study. Preliminary investigation has revealed that the proposed INCO has an overall efficiency of 60-70% and thermal efficiency of 35-40%. Hybridization of the engine has reduced the emission of Nitrogen Oxides (NOx) by 13%. NOx is predominantly temperature dependent.
