Actual Fuel Velocity of Injection Considering Orifice Flow Coefficient

Go Actual Fuel Velocity of Injection = Flow Coefficient of Orifice*sqrt((2*(Injection Pressure-Pressure in Cylinder during Fuel Injection)*100000)/Density of Fuel)

Volume of Fuel Injected Per Second in Diesel Engine

Go Volume of Fuel Injected per Second = Area of All Orifices of Fuel Injectors*Actual Fuel Velocity of Injection*Total Time Taken for Fuel Injection*Number of Injections per Minute/60

Fuel Jet Velocity

Go Fuel Jet Velocity = Coefficient of Discharge*sqrt(((2*(Fuel Injection Pressure-Pressure of charge inside the cylinder))/Density of Fuel))

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)

Energy Content per Unit Cylinder Volume of Mixture Formed in Cylinder of Diesel Engine

Go Energy Content per Unit Cylinder in Diesel Engine = (Density of Air*Lower Heating Value of Fuel)/(Relative Air Fuel Ratio*Stoichiometric Air Fuel Ratio)

Energy Content Per Unit Cylinder Volume of Mixture Formed Prior to Induction into Cylinder

Go Energy Content per Unit Cylinder = (Density of Mixture*Lower Heating Value of Fuel)/(Relative Air Fuel Ratio*Stoichiometric Air Fuel Ratio+1)

Fuel Velocity at Time of Release into Engine Cylinder

Go Fuel Velocity at Tip of Nozzle = sqrt(2*Specific Volume of Fuel*(Injection Pressure-Pressure in Cylinder during Fuel Injection))

Area of all Orifices of Fuel Injectors

Go Area of All Orifices of Fuel Injectors = pi/4*Diameter of Fuel Orifice^2*Number of Orifices

Total Time Taken for Fuel Injection in One Cycle

Go Total Time Taken for Fuel Injection = Time of Fuel Injection in Crank Angle/360*60/Engine RPM

Fuel Consumption Per Cycle

Go Fuel Consumption per Cycle = Fuel Consumption per Cylinder/(60*Number of Cycles per Minute)

Volume of Fuel Injected Per Cycle

Go Volume of Fuel Injected per Cycle = Fuel Consumption per Cycle/Specific Gravity of Fuel

Fuel Consumption per Cylinder

Go Fuel Consumption per Cylinder = Fuel Consumption per Hour/Number of Orifices

Fuel Consumption Per Hour in Diesel Engine

Go Fuel Consumption per Hour = Brake Specific Fuel Consumption*Brake Power

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

Number of Fuel Injections Per Minute for Four Stroke Engine

Go Number of Injections per Minute = Engine RPM/2

Number of Fuel Injections Per Minute for Four Stroke Engine Formula

Number of Injections per Minute = Engine RPM/2
N_i = ω_e/2
