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)

Time taken for engine to cool

Go Time taken to cool Engine = (Engine Temperature-Final Engine Temperature)/Rate of Cooling

Engine rpm

Go Engine RPM = (Speed of vehicle in mph*Gear Ratio of Transmission*336)/Tire Diameter

Kinetic energy stored in flywheel of IC engine

Go Kinetic energy stored in the flywheel = (Flywheel moment of inertia*(Flywheel angular velocity^2))/2

Swept Volume

Go Swept volume = (((pi/4)*Inner Diameter of Cylinder^2)*Stroke Length)

Work done per operating cycle in IC engine

Go Work done per operating cycle = Mean effective pressure in pascals*Displacement volume of piston

Brake output per displacement of piston

Go Brake output per displacement = Brake power per cylinder per stroke/Displaced volume

Engine specific volume

Go Engine specific volume = Displaced volume/Brake power per cylinder per stroke

Brake specific power

Go Brake specific power = Brake power per cylinder per stroke/Area of Piston

Equivalence ratio

Go Equivalence ratio = Actual Air Fuel Ratio/Stoichiometric Air Fuel Ratio

Brake work per cylinder per stroke

Go Brake work per cylinder per stroke = Bmep*Displaced volume

Compression Ratio given Clearance and Swept Volume

Go Compression Ratio = 1+(Swept volume/Clearance volume)

Engine Capacity

Go Engine capacity = Swept volume*Number of Cylinders

Mean piston speed

Go Mean Piston Speed = 2*Stroke Length*Engine Speed

Peak torque of engine

Go Peak Torque of Engine = Engine Displacement*1.25

Engine specific volume Formula

Engine specific volume = Displaced volume/Brake power per cylinder per stroke
BSV = V_d/W⋅_b

What is specific volume?

Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. It is the ratio of a material's volume to its mass, which is the same as the reciprocal of its density. In other words, specific volume is inversely proportional to density.
