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

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

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.

CAN obd2 read fuel consumption?

Being able to connect to the OBD-II will not only provide real-time fuel economy data. You will be able to monitor information such as speed, coolant temperature, CO2 emission, L/H, L/100KM and many others.

How do you calculate fuel consumption using odometer?

Calculate

1. Get the miles traveled from the trip odometer, or subtract the original odometer reading from the new one.
2. Divide the miles traveled by the amount of gallons it took to refill the tank. The result will be your car’s average miles per gallon yield for that driving period.

How do you calculate diesel?

Fill the tank again and note the number of litres put in. Divide the number of miles driven by the amount of fuel used in litres (miles per litre)…How To Calculate Your Fuel Consumption

1. Your mileage since the last fill.
2. The number of litres of fuel you put in.
3. The cost per litre of fuel.

Does Eco obd2 work?

Overall, Effuel works similarly to other OBDII performance chips sold online today. It’s easy for anyone to install, works within minutes, and can significantly improve the performance of your vehicle.

What should fuel level input be?

FUEL LEVEL = FUEL_PCT: Fuel level input is a very useful parameter when you’re attempting to complete system monitors and diagnose specific problems. For example, the misfire monitor on a 1999 Ford F-150 requires the fuel tank level to be greater than 15%.

How do I calculate fuel consumption per Litre?

The actual formula to get km per litre is 100 divided by 8 = 12.5 (Your car will give you 12.5 km on one litre)….To convert Formula to use.

km per litre to litres per 100 km	divide 100 by km per litre
litres per 100km to km per litre	divide 100 by litres per 100 km

How many kms Can a truck run in 1 litre of diesel?

Today, the average mileage that trucks can manage on Indian roads is about four kms a litre, increasing their average trip expenses to over Rs 1 per tonne-km. A normal 16-tonne truck can clock no more 250-400 kms a day in India, compared to 700-800 kms in developed countries.

Is the OBD2 sensor used for fuel flow rate?

I have been working on a project where i want to calulate fuel flow rate using data from the obd2 sensor. The car on which i was testing didn’t support the pid 015E which is for fuel flow rate. Then i planned to use pid 0110 which is for mass air flow (MAF).I was unlucky with that too (not supported).

Where can I find OBD data for my car?

Consumption calculation Consumption can be evaluated from OBD data directly from a parameter (PID) of SAEJ1979 standard [7] (or using a non-standard car manufacturer parameter) or if not available, from intake airflow sensor and air/fuel ratio sensor.

How are intake airflow sensors used to calculate fuel consumption?

To calculate the fuel consumption of vehicles, the intake airflow value is needed: the intake airflow sensors are usually found in diesel vehicles and in some spark ignition vehicles. Figure 1 Intake airflow sensor of a Citroen C3 1.4 HDi (Diesel engine) compared with Horiba OBS 1300 exhaust flow sensor.

How is power consumption measured in a car?

Consumption has been measured with the CVS and with a portable emission analyzer (HORIBA OBS-1300). A calibration procedure has been also developed in which 3 tests on a dynamometer chassis are needed: the maximum power curve, the curve at idle and a curve at fixed rpm varying the engine load.
