How is diesel engine fuel consumption calculated?

Simple Method

  1. Formula To Estimate Maximum Engine Fuel Consumption. Gallon Per Hour (GPH) = (specific fuel consumption x HP)/Fuel Specific Weight.
  2. 300-hp Diesel Engine Example. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.
  3. 300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.

How do you calculate DG kWh?

Easiest way(may not be accurate) Take the mechanical power of the engine in bkw, it would be specified by the manufacturer. Multiply it with the electrical efficiency of the alternator this would also be specified by the manufacturer. That should give you the KWh of the genset.

How do you calculate the specific fuel consumption of a marine diesel engine?

SFOC (g/kwh) = Mass of fuel consumed per hour / Power developed in KW

  1. The readings of the flow meter to the main engine should be noted over the specified time interval say 1 hour.
  2. The mass of the observed volume of fuel consumed can be determined by following the above-said bunker calculation procedure.

What is the formula for specific fuel consumption SFC?

Gathering all the terms together, TSFC is the mass of fuel burned by an engine in one hour divided by the thrust that the engine produces. The units of this efficiency factor are mass per time divided by force (in English units, pounds mass per hour per pound; in metric units, kilograms per hour per Newton).

How do you calculate the efficiency of a generator?

The efficiency of a generator is determined by the power of the load circuit and the total watts produced by the generator. It is expressed as a percentage since you are dividing units of power by units of power. For most commercial electrical generators, this ratio can be upwards of 95 percent.

How do you calculate fuel consumption per hour?

Calculate your average speed by dividing the number of miles you traveled by how long it took you. For example, if you traveled 200 miles and it took you 4 hours, then 200 / 4 = 50 miles an hour on average. Divide your average speed by the miles per gallon to find how many gallons per hour of fuel you’re burning.
