Question: hydrocarbon fuel c12 h26 is burned at gaz state in...

Question details

hydrocarbon fuel C12 H26 is burned at gaz state in a Ci engine having a bore b=100mm and stroke lenght L=125mm the compression ratio is 16 exhaut dry analysis of combustion product give the following percentages
12.5% CO2 /0.5%CO/ 3.8%O2
determine the chemical reaction of this combustion ?
calculate the equivalent ratio phi at which the engine operate ?
calculate the residual mass left un the cylinder at the end of exhaut stroke the exhaut gas pressure is 1.08bar and temperature is 427degree celcuis m residual=?
calculate the power produced by the engine in case the fuel enter at 25 degree celcuis at rate mf =0.5mol/l?
at 127 degree celcuis and heat loss of 100Mj/kg precise the flow rate mf dot and mg dot?
