The duration that a star spends on the main sequence depends primarily on the amount of fuel it has to fuse and the rate at which it fuses that fuel, i.e.

Supplying the fuel to the engine Fuel is transported from the fuel tank (via fuel lines) and pressurised using fuel pump(s).

The example below shows the amount of time required for a star of 20 to consume all of its nuclear fuel.

Fuel stations in Uganda are running out of fuel.

Water causes corrosion of fuel system components (pumps, fuel lines, etc.

The fuel injector ensures that the fuel is broken down into small droplets, and that the fuel is distributed evenly.

This can be performed directly in a direct carbon fuel cell, direct ethanol fuel cell or a microbial fuel cell.

A flexible fuel vehicle (FFV) or dual fuel vehicle (colloquially called a flex fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank.

Diesel fuel in general is any liquid fuel used in diesel engines, whose fuel ignition takes place, without spark, as a result of compression of the inlet air mixture and then injection of fuel.

The two ships had different fuel stores Bismarck was designed to carry 3,200 tons of fuel oil, but could store up to 6,400 tons of fuel in a normal configuration with extra fuel bunkers, the fuel carried could be increased up to 7,400 tons.

In the UK, the Renewable Transport Fuel Obligation obliges suppliers to include 5 renewable fuel in all transport fuel sold in the UK by 2010.

Fuel economy In 2004 UPS announced that it would save fuel by minimizing left turns.

CA No, no. The argument that it's a bridge fuel makes sense, because the amount of CO2 per unit of energy is lower than oil and coal, correct?

Food is fuel for our bodies.

One of the latest innovation within the Brazilian flexible fuel technology is the development of flex fuel motorcycles.

The catalyst free hydrocarbons are routed to a main fractionator for separation into fuel gas, LPG, gasoline, naphtha, light cycle oils used in diesel and jet fuel, and heavy fuel oil.

Now, at the standard rate of fuel consumption, I would like to see the computer trace the flight path of this rocket and see how it can determine, at any instant, say at the end of 40 seconds, the amount of fuel remaining, and the velocity at that set instant.

Well, saving that fuel, 69 percent of the fuel in light vehicles costs about 57 cents per saved gallon.

Reprocessed uranium (RepU) Reprocessed uranium (RepU) is a product of nuclear fuel cycles involving nuclear reprocessing of spent fuel.

This is the conventional nuclear fuel cycle.

The second task is fuel efficiency. Okay?

Again, much cheaper than buying the fuel.

We're pushing fuel efficiency to new heights.

It only adds fuel to the fire.

This heating device uses oil as fuel.

Gasoline is no longer a cheap fuel.

This car consumes a lot of fuel.

Because of short supplies of fuel, these generators are fed with a locally produced fuel that is extracted from plastic.

Types of fuel cells design Fuel cells come in many varieties however, they all work in the same general manner.

Pu 239 is a viable fuel and must be accounted for even when a highly enriched uranium fuel is used.

In 2006 Fiat introduced the Fiat Siena Tetra fuel, a four fuel car developed under Magneti Marelli of Fiat Brazil.

However, even if all the coffee grounds in the world were used to make fuel, the amount produced would be less than 1 percent of the diesel used in the United States annually.
