Engine Capacity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Engine capacity = Swept volume*Number of Cylinders
EC = V_s*k
This formula uses 3 Variables

Variables Used

Engine capacity - (Measured in Cubic Meter) - Engine capacity is the displacement volume of a cylinder multiplied by the number of cylinders in an engine.
Swept volume - (Measured in Cubic Meter) - Swept volume is the volume between the top dead center (TDC) and bottom dead center (BDC).
Number of Cylinders - Number of Cylinders is the count of the cylinders that are present on the engine.

STEP 1: Convert Input(s) to Base Unit

Swept volume: 1178 Cubic Centimeter --> 0.001178 Cubic Meter (Check conversion here)

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 Capacity Formula

Engine capacity = Swept volume*Number of Cylinders
EC = V_s*k

What is Engine Capacity ?

Engine capacity is the measurement of the total volume of the cylinders in the engine. The bigger the engine size, the more space there is for air and fuel inside it.
