This formula uses 3 Variables
Variables Used
Brake work per cylinder per stroke - (Measured in Joule) - Brake work per cylinder per stroke is defined as the work done on the single piston per one stroke due to the brake power obtained in that cylinder.
Bmep - (Measured in Pascal) - Bmep is defined as the average pressure which, if imposed on the pistons uniformly from the top to the bottom of each power stroke, would produce the measured power output.
Displaced volume - (Measured in Cubic Meter) - Displaced volume is defined as the volume covered by the piston during one complete stroke in IC engine.
STEP 1: Convert Input(s) to Base Unit

22 Fundamentals of IC Engine Calculators

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

Brake work per cylinder per stroke Formula

Brake work per cylinder per stroke = Bmep*Displaced volume
Wb = Bmep*Vd

What is brake work per stroke?

The engine develops power during its running. The power obtained at the crankshaft is known as brake power.The resultant work done on the piston due to this power is called as the brake work for one stroke. One stroke signifies the displacement of piston from either TDc to BDC or vice versa.
