## < 22 Fundamentals of IC Engine Calculators

Overall heat transfer coefficient of IC engine
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
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
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
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
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
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
Engine Displacement = Engine bore*Engine bore*Stroke Length*0.7854*Number of Cylinders
Rate of cooling of engine
Rate of Cooling = Rate of Cooling Constant*(Engine Temperature-Engine surrounding Temperature)
Time taken for engine to cool
Time taken to cool Engine = (Engine Temperature-Final Engine Temperature)/Rate of Cooling
Engine rpm
Engine RPM = (Speed of vehicle in mph*Gear Ratio of Transmission*336)/Tire Diameter
Kinetic energy stored in flywheel of IC engine
Kinetic energy stored in the flywheel = (Flywheel moment of inertia*(Flywheel angular velocity^2))/2
Swept Volume
Swept volume = (((pi/4)*Inner Diameter of Cylinder^2)*Stroke Length)
Work done per operating cycle in IC engine
Work done per operating cycle = Mean effective pressure in pascals*Displacement volume of piston
Brake output per displacement of piston
Brake output per displacement = Brake power per cylinder per stroke/Displaced volume
Engine specific volume
Engine specific volume = Displaced volume/Brake power per cylinder per stroke
Brake specific power
Brake specific power = Brake power per cylinder per stroke/Area of Piston
Equivalence ratio
Equivalence ratio = Actual Air Fuel Ratio/Stoichiometric Air Fuel Ratio
Brake work per cylinder per stroke
Brake work per cylinder per stroke = Bmep*Displaced volume
Compression Ratio given Clearance and Swept Volume
Compression Ratio = 1+(Swept volume/Clearance volume)
Engine Capacity
Engine capacity = Swept volume*Number of Cylinders
Mean piston speed
Mean Piston Speed = 2*Stroke Length*Engine Speed
Peak torque of engine
Peak Torque of Engine = Engine Displacement*1.25
