Overall heat transfer coefficient of IC engine

Go Overall Heat Transfer Coefficient = 1/((1/Heat Transfer Coefficient on Gas Side)+(Thickness of Engine Wall/Thermal conductivity of material)+(1/Heat Transfer Coefficient on Coolant Side))

Fuel Jet Velocity

Go Fuel jet velocity = Coefficient of Discharge*sqrt(((2*(Fuel injection pressure-Pressure of charge inside the cylinder))/Fuel Density))

Rate of convection heat transfer between engine wall and coolant

Go Rate of Convection Heat Transfer = Convection Heat Transfer Coefficient*Surface Area of Engine Wall*(Engine Wall Surface Temperature-Temperature of Coolant)

Mass of air taken in each cylinder

Go Mass of air taken in each cylinder = (Intake air pressure*(Clearance volume+Displaced volume))/([R]*Intake air temperature)

Heat transfer across engine wall given overall heat transfer coefficient

Go Heat Transfer across Engine Wall = Overall Heat Transfer Coefficient*Surface Area of Engine Wall*(Gas side temperature-Coolant Side Temperature)

Power produced by IC engine given work done by engine

Go Power produced by IC engine = Work done per operating cycle*(Engine speed in rps/Crankshaft revolutions per power stroke)

Engine displacement given number of cylinders

Go Engine Displacement = Engine bore*Engine bore*Stroke Length*0.7854*Number of Cylinders

Rate of cooling of engine

Go Rate of Cooling = Rate of Cooling Constant*(Engine Temperature-Engine surrounding Temperature)

t = (T-T_f)/R_c

What is the time taken for the engine to cool?

Newton’s law of cooling defines the rate at which an exposed body changes temperature by radiation, which is roughly equal to the difference in temperature between the item and its surroundings, Using Newton’s rule of cooling, we can determine how quickly a substance at a given temperature will cool in any given environment. Furthermore, it explains how the rate of cooling of an object is affected not only by the temperature differential between the material and its surroundings but also by the cooling constant of the material.
