In present work, simulation has been done for four stroke compression ignition engine for progressive combustion. Result of Progressive combustion simulation was validated with result available in literature. Graph of P-V, P-θ and T-θ were plotted for progressive combustion at stoichiometric Air-Fuel ratio. We observed that maximum temperature was 2824.49 K at crank angle in degree 381.61. Indicated power, Brake power, Indicated thermal efficiency and Brake thermal efficiency obtained from the simulation was good in agreement with the literature results. The difference between present work and literature was 2.58%, 3.11%, 5.24% and 4.73% respectively. Variations in power, mean effective pressure and efficency are presented by changing speed in graphical form. The value of Indicated power and Indicated thermal efficiency obtained from simulation of progressive combustion was 10.207 kW and 46.373%.

ABSTRACT

INTRODUCTIONGanesan, V. (2000) suggested that computer simulation can give major contribution to engine design at different levels of general studies, or detail, corresponding to a different stages of model development. In this research, the progressive com-bustion modeling of single cylinder for four stroke direct injec-tion diesel engine developed considering single zone com-putational thermodynamic model. It is assumed that there is spatial uniformity of pressure, temperature and composition of the cylinder content at each crank angle. Combustion proc-ess considered as progressive combustion process. Air-fuel mixture is considered an ideal gas. The analysis of model covers of compression, power and expansion processes and neglecting gas exchange process during intake and exhaust. I considered the effects of heat losses, friction and tempera-ture-dependent specific heats into performance analysis. This model can predicts in-cylinder temperatures and pressures as functions of the crank angle (θ). It can provide more realis-tic estimations of the main performance parameters, such as efficiency and mean effective pressure.

Heat released from combustion is distributed evenly through-out the cylinder. Taking stoichiometric Air-Fuel ratio, compute the adibatic flame temperature T3 at constant volume by Newton Raphson technique (Rakopoulos, C. D. , Hountalas, D. T., Rakopoulos, D. C., & Giakoumis E.

Performance of 4 stroke single cylinder compression ignition engine with varying speed at stoichiometric Air-Fuel ratio

Fig. 4. Power Vs Speed

Fig. 5. Efficiency Vs Speed

According to figure no. 4, the engine speed is at 1500 RPM the Indicated Power (IP) of engine is 10.207 kW. If the engine speed is increase, IP also increases. Brake Power (BP) is increase till in 5000 rpm and then decrease and go to down because friction power increases. Maximum bp is 23.742 KW on the engine speed is 6000 RPM. .

According to figure no. 5, Indicated Thermal Efficiency (ITH-EFF) is maximum equal to 47.032% and as speed increased, change in ITHEFF is negligible but brake thermal efficiency (BTHEFF) reduced. When the engine speed is increased, BTHEFF reduced from 40.593% because friction power in-crease.

According to figure no. 6, maximum indicated MEP is 14.977 bars at high speed. It is constant but brake MEP reduced from 12.928 bars as speed increased due to increment in the fric-tion power and net output at engine shaft is reduced.

CONCLUSION AND FUTURE WORK PROPOSAL1. The variation of specific heats reduces the temperature

and pressure of the gases after the compression stroke and at the end of combustion in I.C. engine.

2. Heat transfer deteriorate the performance of the com-pression stroke in I.C. engine

3. Incomplete combustion of the fuel is major loss as the fuel supplied to the engine is in tiny droplets of liquid fuel. The evaporation, mixing and combustion take place inside the engine.

4. Large divergence in efficiency in present work with actual engine is partly due to valve operation, incomplete com-bustion and gas exchange process.

Ghojel, J., & Honnery D. (2005), Gogoi, T. K., & Baruh, D. C. (2010) suggest that progressive combustion simulation is simple, low computational cost and reasonable accurate as

more complex models. This model is not however reliable, it does not cover the fluid flow analysis and do not take care of premixed and diffusive combustion

Lipkea, W. H, & De Joode, A.D. (1989) suggest that two-zone is better than single zone modeling. Quintero, H. F., Romero, C. A., & Useche, L. V. (2007) suggest four-zone or multi-zone models increased accuracy and flexibility for such complex phenomena as the formation of nitric oxide and soot in engine cylinders. Three dimensional Computational Fluid Dynamics modeling would be essential to understand the phenomenon. (Stone R., 1992)
