CONCLUSION AND FUTURE SCOPE A. Conclusion From this experimental work, we conclude the following results, 1) The Break thermal efficiency, Mechanical efficiency and Indicated Thermal efficiency are higher for the compression ratio of 17 compared to other compression ratios. 2) Break Specific fuel consumption is lower and Break Power is almost similar with minor variations for the compression ratio of 17 compared to other compression ratios. 3) The various emissions namely CO, HC, NOx and decreasing for the compression ratio 17 compared to other compression ratios. 4) The NOx emission increasing for all the compression ratios due to the increase in cylinder temperature. However, still NOx is lower in the case of 17, compression ratio due to proper combustion. 5) The Smoke emission is also lower for all the compression ratios at higher loads due to enhanced combustion. B. Future Scope Researchers can future work on different compression ratios with fuel blending in the diesel engines. Someone can extend the work for different compression ratios with a varying injection pressure of diesel engines.
