How do you calculate the specific fuel consumption of a diesel engine?
Simple Method
- Formula To Estimate Maximum Engine Fuel Consumption. Gallon Per Hour (GPH) = (specific fuel consumption x HP)/Fuel Specific Weight.
- 300-hp Diesel Engine Example. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.
- 300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.

Does obd2 show fuel consumption?
Some OBD-II trip computers will provide information on current and previous trips. This includes Avg speed, Avg fuel consumption and distances. They may also provide data on the routes travelled.
What is the formula for specific fuel consumption Mcq?
Explanation: The unit of specific fuel consumption is given by kg/kW-hr. The formula for specific fuel consumption is C=\frac{Q_f}{P} where Qf is fuel flow rate, P is power and C is specific fuel consumption. 3.
What is the need of measurement of fuel consumption?
Most of the operating costs of a ship are fuel related. Therefore it is very important to use fuel in the most efficient way. The real-time measurement of fuel consump- tion provides helpful information for shipowners, shipmanagers and crew about the influences of their actions on the consumed fuel.
How does ECU calculate mpg?
The ECU has calculated how long to open each injector for each cycle. By adding up all the open time in a short time and multiplying by the known flow rate the volume of fuel used is known. Divide the distance traveled in a set time by the fuel used in the same time and multiply by a constant will give the mpg.
What fuel oil system uses to add pressure of fuel and deliver to the engine?
The fuel supply pump, often referred to as the lift pump, is responsible for drawing fuel from the tank and delivering it to the high pressure pump. Modern day fuel pumps can be electrically or mechanically driven by the engine.
How do you calculate the fuel consumption of a diesel engine?
The formula is : Energy in output : E = P*h*d (kWh) Consumption of fuel : C = E*Ckwh (liter) Where E = active electric energy in output of the diesel engine in kWh P = active electric power in output…
How to calculate the fuel consumption of a power generator?
The formula is : Energy in output : E = P*h*d (kWh) Consumption of fuel : C = E*Ckwh (liter) Where. E = active electric energy in output of the diesel engine in kWh. P = active electric power in output of the diesel engine in kW. h = number of hours per day the genset runs. d = number of days the power generator runs.
Do diesel engines consume a lot of fuel?
Diesel engines consume fuel according to their power requirements. A correctly tuned diesel engine consumes fuel according to its power requirements. Simple really, the more power you produce the more fuel you use. The fuel consumption rate for many makes of Diesel Engines can be found in a range between 0.380 & 0.450 lbs/hp hour;
What happens if fuel consumption calculations are wrong?
Inaccurate calculations can lead to incorrect budget predictions, the wrong vehicles being purchased, route inefficiency and a number of other problems that will negatively affect the success of your fleet. So how is fuel consumption calculated?
