How do you calculate fuel consumption of a diesel engine per hour?
- 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.

How much fuel does a diesel engine burn while idling?
Idling a heavy-duty truck consumes about 0.8 gallon of fuel per hour. Even when diesel costs as little as $2.50 a gallon, fuel for one 10-hour rest period will cost $20. Typically, a long-haul truck idles about 1,800 hours per year, using about 1,500 gallons of diesel.
How much fuel does a diesel engine burn?
Industrial generators can burn up to 150 gallons of diesel fuel per hour, while small ones can use as little as 0.6 gallons. These machines run most efficiently at 75 to 100 percent of their recommended rating.
Do diesel engines burn fuel while idling?
Diesels do burn very little fuel at idle because unlike gasoline engines, their throttles do not restrict the amount of air they ingest. … You should let your engine idle for a few minutes to warm up before getting underway. As noted above, a diesel will not warm to operating temperature until it is under load.
How do you calculate fuel 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.
How do you calculate diesel 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.
Why do truckers leave their diesel engines running?
Truckers, both independent owner-operators and fleet drivers, leave their engines idling for three main reasons: weather conditions, economic pressures, and old habits. In cold weather, a truck’s engine and fuel tank need to stay warm.
Is it bad to idle a diesel engine?
Unnecessary idling wastes fuel, causes air pollution and increases engine wear. An idling diesel engine produces much higher emissions than it would while using the same amount of fuel under load. Extended idling causes a build-up of soot inside the engine and results in a puff of black smoke when the engine revs.
How much diesel does a truck burn per mile?
Now, you can calculate your per-mile fuel spending. Take the current per-gallon price of diesel ($2.10) and divide it by your truck’s miles per gallon. So, $2.10 divided by 5.7 equals 36.84 cents. If you round that number up, you are spending 37 cents on fuel for every mile your truck travels.
Does diesel burn quickly?
If you toss a lit match into a puddle of diesel fuel, it’ll go out. That’s because diesel is much less flammable than gasoline. In a car, it takes intense pressure or sustained flame to ignite diesel.
Can diesel burn by itself?
Diesel is instead classified as a combustible liquid. But make no mistake about it, diesel can and will burn.
