Fuel injection for required Torque.
Hello Engineers,
i wants to know the Exact formula to calculate the fuel consumption of the required Torque.any formula is there to calculate?for example if the torque requested is 50Nm then what quantity of fuel will inject in the four stroke Diesel engine?Please help me .Thanks in Advance😀

this is a rough derivation. someone correct me if iv made a mistake.
1 gallon of diesel contains = 147,000 btus
1 hp = 42.44 btu/min
to make 1 hp you need to use 0.0002887 gallons of diesel / minute
1 hp = (torque x rpm)/5252
torque = (0.0002887 gallons/min) x (5252/rpm)
torque produced = [gallons/minute] x [1.5162/rpm]
substitute gallons per minute of diesel and crank rpm into the above formula and you have your torque in lb-ft.
in the meantime let me see if i can dig up some formulas from somewhere.
