Abstract: Today in every nation's agenda, the utmost priority is given to reduce the impact of pollution (emissions related to air and water) that is created through different sources. This pollution is highly impacting our life on the daily basis. The best way is to reduce the pollution by encouraging usage of environment friendly activities. Moreover, the rate by which our conventional (non-renewable) sources of fuel depleting is really alarming and might perish in long run. The only way for the sustainable development is by adopting eco-friendly and renewable sources of fuel. Oxygenated fuel is an alternative fuel for the diesel engine because it is reversible in nature and its emissions are low. This paper has focused on the impact of different modification made in CI (compression ignition) engines in order to work at their optimum level in terms of combustion, emission and performance. The modification in engine had carried out by varying injection pressure (IP), injection timing (IT),compression ratio (CR), combustion chamber geometry etc. Results show that at high value of CR, IP and retardation or advancement of IT shows the improvement in the combustion, performance and emissions characteristics of CI engines. At modified conditions brake specific fuel consumption, unburned hydrocarbon, smoke opacity and carbon monoxide emission decreases and brake thermal efficiency and nitrogen oxide emission increases as compared to without modified ones. The result also shows that retarded injection timing as compared to original injection timing, emission of nitrogen oxide decreases.
