Internal combustion engines are widely used worldwide for transportation, shaft energy production, marine applications etc. Increasing the efficiency of internal combustion engines is one of the most promising and cost-effective approaches to dramatically improving the fuel economy of the on-road vehicle fleet in the near- to mid-term. The present paper gives a brief introduction of an Internal Combustion Engine and its application, Investigation of the effect of addition of browns gas to air fuel mixture in combustion of 4 stroke SI Engine, The porous medium technology for an I.C engines, concept of Nano Internal Combustion Engine, Novel Otto cycle engine concept and S.I.Engine with Quasi-constant volume Cycle (QCV).
