Overall Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - Overall heat transfer coefficient is the overall convective heat transfer between a fluid medium (a fluid) and the surface (wall) flowed over by the fluid.
Heat transfer coefficient on gas side - (Measured in Watt per Square Meter per Kelvin) - Heat transfer coefficient on gas side is defined as the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat from engine side.
Thickness of engine wall - (Measured in Meter) - Thickness of engine wall is defined as the measure of the distance between the outer and inner side of the engine wall.
Thermal conductivity of material - (Measured in Watt per Meter per K) - Thermal conductivity of material is defined as a measure of a material’s ability to conduct heat.
Heat transfer coefficient on coolant side - (Measured in Watt per Square Meter per Kelvin) - Heat transfer coefficient on coolant side is defined as the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat to the coolant side.

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))
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)
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)
Compression Ratio given Clearance and Swept Volume
Compression Ratio = 1+(Swept volume/Clearance volume)
