How many gallons of fuel does an idling engine consume per hour?
Idling uses up to ½ gallon of fuel per hour (although it varies depending on the type and size of the engine). It may not seem like much, but idling for a few minutes everyday can cost you several dollars per week.
How do I calculate HP fuel consumption?
Expressed as a formula it looks like this:
- Given Horsepower x .50 lb fuel/hp = lbs of fuel for given horsepower.
- 200 lbs/hr / 6.25 lbs/gal = 32 gph.
- BSFC . 50 / 6.25 = . 0800 gallons / horsepower / hour.
- OR.
- BSFC .70 / 6.59 = .106 gallons / horsepower / hour.
- 800 * .106 = 84.80 gph.
How much fuel does a 2 Litre engine use?
If a four-cylinder engine is described as a 2.0-litre, this means each piston can compress roughly 500cc of fuel and air into the combustion chamber every revolution the engine turns.
What engine consumes the most fuel?
Maybach 57 is a luxury rhino-like vehicle fitted with a 6-litre V12 engine that consumes 1 litre per 5.7 km on a highway. Bentley Meteor is officially recognized as “the most fuel-hungry” vehicle in the world. To go 100 km, it requires 117 litres of fuel.
How much gas does a 4 cylinder idle use?
Generally, an idling car uses somewhere between 1/5 to 1/7 gallon of fuel per hour. Compact cars that carry a 2-liter capacity engine burn around 0.16 – 0.3 gallons of gas on a per hourly basis. A large sedan, on the other hand, with a 4.6-liter engine, burns approximately 0.5 – 0.7 gallons of gas while idling.
Why is idling bad for an engine?
Ten seconds of idling can burn more fuel than turning off and restarting the engine. Plus, excessive idling can damage your engine’s components, including spark plugs, cylinders and exhaust systems. This is the gunk that can foul your sparkplugs and muck up your exhaust systems.
How do you calculate fuel consumption of a gas 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.

How much fuel does my engine need?
The amount of horsepower that your engine has will determine how much fuel flow is required to support that engine. As horsepower increases so does the volume of fuel required to support that power. A good estimator of volume to power is approximately 10 hp per gallon or 2.64 hp per liter.
What size is a 4 cylinder engine?
Displacement. Petrol straight-four engines used in modern production cars typically have a displacement of 1.3–2.5 L (79–153 cu in), however larger engines have been used in the past, for example the 1927-1931 Bentley 4½ Litre.
What is a good fuel consumption?
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). In this instance, the higher the number of kilometres travelled the more fuel-efficient.
How to calculate fuel consumption for a 400 hp gas engine?
To calculate Fuel Consumption for a 400 hp Gas engine with a BSFC of.50 lbs/hp/hr: 400 hp x.50 = 200 lbs/hr To convert this lbs/hr to a more meaningful gallons per hour we use t he conversion rate from lbs to gallons which is 6.25 lbs to 1 gallon of gas 200 lbs/hr / 6.25 lbs/gal = 32 gph
How much fuel does a vehicle consume while idling?
However, the amount of fuel a vehicle consumes while idling varies depending on factors such as its weight, engine size, and the type of fuel it takes. Some states and local governments even have anti-idling laws that restrict engine idling and impose fines on drivers who violate them.
How much fuel do you need to produce hp?
Fuel flow (GPH) = 0.0226 x HP / TE. You can calculate how much fuel you will need to produce a certain amount of HP with these calculations. You can also figure out how much real HP any engine is making. Regardless of what someone may tell you, most engines make in the region of 30\% TE.
What is the BSFC of a 400 hp gas engine?
BSFC .50 / 6.25 = .0800 gallons / horsepower / hour. Again we calculate Fuel Consumption for a 400 hp Gas engine. Remember, if you are running E85 or Methanol be sure to use those BSFC values in your formula as well as the appropriate lb/gal conversion value for your chosen fuel..
