what is the difference between fuel and propellant?
532283
A fuel is a substance that can burn in the presence of oxygen. An oxidizer is a source of oxygen. A propellant is the combination of fuel and oxidizer. It is the chemical mixture that is burned to provide propulsion.

What is the Difference Between Oxygenated and Non Oxygenated Gasoline? Oxygenated gasoline is a form of fuel which has ethanol as an additive to increase the oxygen content of the fuel. ... Non-oxygenated gasoline is a form of gasoline which has no additives which increase the oxygen content of the fuel.

A fuel is just anything you can burn to produce energy. Most notably, petroleum oil gives you gasoline (which is known as "petrol" in countries speaking British English) and diesel fuel (used to run big trucks and trains).

The main difference between them is that jets get the oxygen to burn fuel from the air and rockets carry their own oxygen, which allows them to operate in space. ... Jet engines have two openings (an intake and an exhaust nozzle). Rocket engines only have one opening (an exhaust nozzle).

The main difference between leaded and unleaded fuel is the additive tetraethyl lead. Leaded gas was commonly used many years ago but it was discovered that lead has undesirable side effects when lead is released into the air. ... Unleaded fuel is also known as petrol or gas depending on where you live.

Petrol is a type of fuel known as gasoline - abbreviated to "gas" in countries such as America. ... "Fuel" is just a general term for any substance that can be utilized for energy. Gas/Petrol (gasoline) is just one type of fuel. It's like this... all gasoline is fuel, but not all fuel is gasoline.

Diesel gas is heavier than jet fuel, with a higher number of slightly larger hydrocarbon chains, though both are primarily paraffin oils (kerosene). Diesel is more viscous than jet fuels.

Vapor is more flammable than a liquid. In this category, gasoline is the more volatile or flammable substance. ... Although it is clear that gasoline is more volatile than Ethyl Alcohol, the biggest difference between the two properties is that one is soluble in water and the other is not.

A gas, on the other hand, has a vol- ume that changes to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily.

The most important properties of gasoline fuels are properties such as volatility and knocking resistance, whereas diesel fuels are required to have important fuel properties such as viscosity, surface tension, and ignition tendency.

Ethanol is a cleaner fuel than gasoline, and it helps reduce emissions when mixed with gasoline. ... On the downside, ethanol is less energy-dense than gasoline – meaning that there's more energy in a gallon of gas than there is in a gallon of ethanol. In general, ethanol has about 33 percent less energy than gasoline.

Substance that burn in air and tend to produce heat and light are known as combustible substances. For combustion it is necessary to have fuel, heat and air. On the other hand, non-combustible substances are the substances that do not undergo combustion in the presence of air.

A - The difference lies in the fuel delivery "feed" to the injector. A top feed injector receives it's fuel from the top of the injector, where the injector top plugs into a fuel rail. The side feed injector receives it's fuel from the side of the injector, where the injector is nested in a fuel rail.

Fuels are dense repositories of energy that are consumed to provide energy services such as heating, transportation and electrical generation. Even though most fuels ultimately get their energy from the sun (see energy conservation) they are usually considered to be a primary energy source.

External vs. In an external combustion engine, the fuel isn't burned inside the engine. With an internal combustion engine, the combustion chamber lies right in the middle of the engine. External engines have a working fluid that is heated by the fuel.

Depending on the grade, jet fuel is basically highly refined kerosene. The kerosene and paraffin difference is that the paraffin is a component of kerosene, and when petroleum refining is complete, it remains as a waxy residue. ...
