1. The problem DIESEL IC ENGINE We were given a excel sheet, with RPM, Torque, Power, Bmep, Fuel mass flow rate, Airmass SFC, Engine Air inlet and Exhaust temp. The engine capacity is 2.2litre 4 stroke. Fuel specifications: 50 Cetane (0.05% Sulphur) Coolant = Fresh water with 45% glycol mix. I am having problems finding Volumetric Efficiency, the fuel calorific value and coolant specific heat. 2. Relevant equations VE=(mRT/P)/(Vswept) VE=(9411*HP*BSFC)/(displacement*RPM) 3. The attempt at a solution I found a VE(volumetric efficiency) of 72.808% for the first speed of 1000RPM with eq: VE=(9411*HP*BSFC)/(displacment*RPM) =(9411*24.2*0.45)/(134*1000) but seem to get the rest above 100% eg @2000RPM VE=133.856% I have tried more than one equation, this seemed to get closer to the 70% VE it should be. I also need to do a heat balance thus i require the calorific value of the diesel (it is not bio diesel fuel) as well as cp for the coolant. Any assistance would be much appreciated.
