Determination of Combustion Process Model Parameters in Diesel Engine with Variable Compression Ratio

Figure 5

Experimental and theoretical rate of heat release diagrams of experimental diesel engine under speeds of n=1960 rpm, fuel injection angle 18.5 (deg CA), BMEP=0.55 MPa. ( and ) are angle of initial (start) of combustion (2% of burned mass) for the first and second Vibe function, respectively.
