Which fuel is more efficient?
Per litre, diesel contains more energy than petrol and the vehicle’s engine combustion process is more efficient, adding up to higher fuel efficiency and lower CO2 emissions when using diesel..
How do I calculate fuel consumption per 100km?
The calculation is: litres / distance * 100 = l/100km. For example: 57 litres / 635 km * 100 = 8.98l/100km. If you know the price of fuel, then you can simply multiply the price per litre by the result and that gives you your cost per 100km.
How do you calculate fuel consumption per hour?
Simple MethodFormula 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.Other Related Resources:
Is 50 miles per gallon good?
But with all that being said, a good MPG figure to aim for is anything between 50 and 60MPG. This will ensure that your car is efficient and economical, which means low running costs and car tax rates.
What is the efficiency of fuel?
Fuel efficiency is measured as the amount of heat that 1 kg of fuel (any fuel) produces on combustion. This is known as the calorific value of the fuel. The unit of measurement of fuel efficiency is kilojoules per kg, i.e. kJ/kg.

How many kilometers per liter will a car go if the engine is 25?
At 25% efficiency, 20*10^5 J (=2 MJ) of chemical (fuel) energy will be required. That will require 1/20 of a liter of gas, since you get 40 MJ of energy per lier. The gas mileage is the reciprocal of that, 20 km per liter.
How do you calculate fuel distance?
To estimate the fuel cost for a trip you must know the trip distance, the average per litre cost of fuel and the vehicle’s fuel consumption.Divide the trip distance by 100.Multiply the result of this by the fuel consumption.Then multiply this figure by the cost of fuel/litre.
Which fuel cell has highest efficiency?
Alkaline Fuel Cells Operating at 60-70ºC (140-158ºF), AFCs are among the most efficient type of fuel cells, reaching up to 60% efficiency and up to 87% combined heat and power.
How can we determine the efficiency of a fuel?
Vehicle fuel efficiency This is known as Brake Specific Fuel Consumption (BSFC) and is determined by the rate of fuel consumption divided by the power produced, expressed as grams per kilowatt-hour and is a measure of the engines fuel efficiency.
How much reserve fuel does a car have?
The fuel gauge in your car or truck is lying to you. Automobile manufacturers build in about a gallon (3.8 liters) of reserve fuel beyond the “empty” line. They also warn about low fuel long before a vehicle runs out, since they know that people procrastinate — especially when it comes to forking over money.
How much fuel left when light comes on?
Generally when the light comes on you have about 2.5 gallons of gas left, which means that your car’s fuel efficiency is the biggest factor in how long you can drive until your car gives out.
What highway speed is most fuel efficient?
According to the U.S. Department of Energy (DOE), most cars’ fuel efficiency peaks at speeds from 35 to 60 miles per hour. After 60, though, fuel efficiency does drop significantly; the DOE says that every 5 miles per hour you drive above 60 is like paying an additional 24 cents per gallon for gas.
At what speed is highway mpg calculated?
Vehicles are tested at a top speed of 80 mph in order to calculate the highway mpg estimates. EPA utilizes five test cycles to represent real-world driving conditions.
What is the formula to calculate fuel consumption?
The following formula is used to calculate fuel consumption in litres / 100kms, the most commonly used measure of fuel consumption. (Litres used X 100) ÷ km travelled = Litres per 100km.
What is the average fuel efficiency?
around 25 miles per gallonThe average car sold in the United States gets an average of around 25 miles per gallon (MPG). We looked at the most fuel-efficient vehicles on the market today, as well as the least fuel-efficient vehicles.
How far can you go with 1 Litre of petrol?
Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km. You’ll often see it referred to as ‘fuel economy’.
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.
