How To Measure Fuel Consumption Of Diesel Engine?

This is the only formula for estimating engine fuel consumption. The Fuel Specific Weight is calculated by multiplying the total hours consumed in liters by the specific fuel consumption x HP. This is a 300-hp diesel engine in action. GPH = (sizes X 300) X (sizes X 300) X (sizes X 300) X (sizes X (7 x 2). Multiply the time by 105/7. 2 to get 16.6 GPH. A 300-hp gasoline engine is depicted in the following example. GPH equals 0 In sequence, I include all 50 x 300)/ 6 inches. A ratio of 150/6 means that one is equal to 150/6 times. 1 gallons per minute is 24.5 gallons per minute. Other materials are also included in this list.

How is diesel engine fuel consumption calculated?

The following formula is used to hypothetically evaluate automotive fuel consumption QS at normal movement (in l(100 km)-1). QS = ge Pe / 36 f V, (1) where ge denotes the specific fuel consumption of a free-piston engine in estimated movement mode, g(kW*h)-1, and Pe is the power absorbed from the crankshaft of the engine.

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

It is not difficult to calculate a vehicle’s fuel usage. Simply record the distance traveled since the last fill-up and the amount of fuel spent to cover that distance, then divide the litres consumed by the kilometres traveled and multiply by 100 to determine consumption in litres per 100 kilometers.

For example, if your vehicle used 60 litres of fuel to travel 450 kilometers, divide 60 by 450 and multiply by 100 for a rounded fuel consumption number of 13.3 litres per 100 kilometers.

With a fuel consumption figure, you can now determine your vehicle’s touring range by dividing the vehicle’s fuel tank capacity by the fuel consumption and multiplying by 100 once more.

What is fuel consumption of diesel engine?

The fuel efficiency of diesel and gasoline are not even close to being comparable. Diesel engines are usually 25% to 35% more fuel efficient than gasoline engines. Diesel engines provide a quarter to a third more “gas” mileage than gasoline engines.

A comparable diesel-powered vehicle will obtain anywhere from 37.5 to 40.5 miles per gallon if a gas-powered vehicle gets 30 miles per gallon. On the worst case scenario, a diesel engine will travel 40 miles for every 30 miles a gasoline engine will travel on the same amount of fuel. On average, a diesel engine will travel 100 miles for every 65 miles a gasoline engine travels on the same amount of fuel.

As a result, comparing the total number of emissions produced per gallon by a gallon of diesel to the total number of emissions produced by a gallon of gas is pointless.

How is diesel engine diesel consumption calculated?

It’s crucial to remember that depending on how fast you’re driving and other factors, your fuel consumption may reduce or increase. A gasoline meter put on your boat is the only true way to measure fuel use. However, while calculating your fuel use isn’t always perfect, it’s a wonderful place to start! On the sea, miles are difficult to measure, hence Gallons Per Hour (GPH) is utilized instead of the conventional MPH.

Pen and Paper Method

“…put in its horsepower rating and multiply it by the specific fuel consumption average, then divide the product by the fuel specific weight,” says the author. *

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

The mass of fuel required per unit time to create one KW is known as specific fuel oil consumption. The SFOC is commonly used to measure the efficiency of marine engines.

Fuel consumption and power developed are always measured over a reasonable time period in favorable weather in order to attain precision. The following is the formula for calculating SFOC:

  • The flow meter readings to the main engine should be recorded for a set time interval, such as one hour. The volume of fuel utilized is calculated using the difference in readings. If the oil is just being delivered to the main engine, it can also be measured by jotting down the HFO service tank reading.
  • Following the above-mentioned bunker calculation process, the mass of the observed volume of fuel consumed can be computed.
  • If a dynamometer is installed on the engine shaft, the horsepower can be measured using a digital indicator that displays the BHP. If not, the horsepower can be computed using engine rpm and average pump fuel index with the help of the manufacturer’s engine characteristic curve from numerous sea trials. However, the calorific value of the fuel utilized for the sea trial may differ, necessitating the determination of a compensating factor to ensure accuracy in calculation.

How do you calculate litres per 100 km?

If you know the price of gasoline, simply multiply the price per litre by the result to get your cost per 100 kilometers. For example, if gas costs $2 per gallon, 8.98l/100km means it costs $17.96 to drive 100 kilometers, or $0.18 per kilometer, excluding other expenditures such as wear and tear.

How much fuel does a 1500cc car consume per kilometer?

The hatchback is extremely popular in Kenya, owing to Honda’s reputation for dependability and durability. Honda Fit debuted in Japan in 2001 and is now in its third generation. On the outside, the car has a boxier appearance, with slash-cut headlamps, alloy rims, and fog lights. Inside, it’s large and capacious, with enough of head, leg, and luggage space.

The car comes standard with an automatic transmission, driver and passenger airbags, a CD/Navigation system, and air conditioning. On the road, the Honda Fit is solid and handles turns effectively with minimum body roll. Its tilt steering and adjustable seats provide for a pleasurable driving experience. It is undeniable that it is one of the top 1500cc automobiles.

The Honda Fit’s 1500cc 4-cylinder engine is mated to a 6-speed manual or CVT transmission and has a FWD powertrain. It accelerates from 0 to 60 mph in 7.9-10 seconds, consumes 19.0 km/L, and produces 130 and 128 horsepower, respectively, with manual and CVT transmissions. It gets 40/33 mpg on highways and city roads, respectively, according to the EPA.

How do you calculate diesel?

You won’t be able to tell if your new driving style and skills are effective unless you know your car’s average miles per gallon (mpg). On-board computers are available in some vehicles, however they are not always reliable.

  • Subtract the number of miles travelled from the litres of gasoline consumed (miles per litre)


Stages one and two are completed by Frank. When he next fills up, his trip meter reads 160.1 miles. Filling his tank takes 22.3 litres. Frank calculates his gasoline consumption to be:
