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

Swept Volume Formula

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

What is total swept volume?

Swept volume is the displacement of one cylinder. It is the volume between top dead center (TDC) and bottom dead center (BDC). As the piston travels from top to bottom, it "sweeps" its total volume.

How to Calculate Swept Volume?

Swept Volume calculator uses Swept volume = (((pi/4)*Inner Diameter of Cylinder^2)*Stroke Length) to calculate the Swept volume, Swept Volume is defined as the volume swept by piston while moving from Top Dead Centre (T.D.C) to Bottom Dead Centre (B.D.C.) This is referred to as V_s. Swept volume is denoted by V_s symbol.

How to calculate Swept Volume using this online calculator? To use this online calculator for Swept Volume, enter Inner Diameter of Cylinder (D) & Stroke Length (L) and hit the calculate button. Here is how the Swept Volume calculation can be explained with given input values -> 7.5E+8 = (((pi/4)*0.08^2)*0.15).

FAQ

What is Swept Volume?

Swept Volume is defined as the volume swept by piston while moving from Top Dead Centre (T.D.C) to Bottom Dead Centre (B.D.C.) This is referred to as V_s and is represented as V_s = (((pi/4)*D^2)*L) or Swept volume = (((pi/4)*Inner Diameter of Cylinder^2)*Stroke Length). Inner diameter of cylinder is the internal or bore diameter of a cylinder & Stroke length is the distance travelled by piston in cylinder from BDC to TDC or vice versa.

How to calculate Swept Volume?

Swept Volume is defined as the volume swept by piston while moving from Top Dead Centre (T.D.C) to Bottom Dead Centre (B.D.C.) This is referred to as V_s is calculated using Swept volume = (((pi/4)*Inner Diameter of Cylinder^2)*Stroke Length). To calculate Swept Volume, you need Inner Diameter of Cylinder (D) & Stroke Length (L). With our tool, you need to enter the respective value for Inner Diameter of Cylinder & Stroke Length and hit the calculate button.
