11. Result and Discussion
 Combustion parameters
 Performance parameters
 Emission parameters
To evaluate suitable operating parameters for Diesel
engine in terms of different injection timings
Presented in ICAER 2013, IIT Bombay, Mumbai

12. Variation of cylinder pressure consumption with crank
angle
Fuel with advanced injection timing shows higher cylinder
pressure
Presented in ICAER 2013, IIT Bombay, Mumbai

13. Variation of ignition delay with load
The higher viscosity of UTO results in shorter ignition delay compared
to diesel
Presented in ICAER 2013, IIT Bombay, Mumbai

14. Variation of heat release rate with crank angle
Retarded injection timing exhibits lower rate of pressure rise due to
reduced ignition delay
Presented in ICAER 2013, IIT Bombay, Mumbai

15. Variation of combustion duration with load
Lower combustion duration is observed due to shorter ignition delay
Presented in ICAER 2013, IIT Bombay, Mumbai

16. Variation of exhaust gas temperature with load
The exhaust gas temperature is lower for advanced injection timing
due to the occurrence of combustion earlier.
Presented in ICAER 2013, IIT Bombay, Mumbai

17. Variation of NO emission with load
Higher combustion temperature results in higher NO emission
Presented in ICAER 2013, IIT Bombay, Mumbai

18. Variation of smoke density with load
The retarded timing of UTO shows higher values of smoke emission
due to incomplete combustion and poor atomization
Presented in ICAER 2013, IIT Bombay, Mumbai

19. Conclusion
Due to variation of injection timing
• Engine was able to run with 100% UTO when the injection timing
was advanced and retarded.
• Based on the combustion, performance and emission the optimum
injection timing is found to be at 20obTDC.
