What Is Jet A Fuel?

Jet A Fuel Jet is a special plane fuel produced to suit the performance of jet engines. It drives large planes which soar in the sky. This fuel is made of oil and it follows the stringent policies in its manufacture. The fuel is Jet A which appears clear or light yellow and burns clean in jet motors.

The fuel is composed of numerous oil content. There can be slight variation of each batch depending on the source of the oil. Nevertheless, Jet A fuel should adhere to strict safety regulations on flying.

Main Types of Jet Fuel

Jet A and Jet A-1

The commonly used jets today are these. Jet A-1 contains special additives that prevent accumulation of static. It is more suitable to work in cold weather as well compared to normal Jet A fuel.

Jet B Fuel

This one is able to cope with way cooler temperatures than Jet A. It got more refrigerated at lower temperatures, and thus it is suitable in extremely cold locations or long flights at high altitudes.

Other Jet Fuel Types

There are countries which use other types of jet fuels. As an illustration of the same, the use of TS-1 fuel is common in the former Soviet countries. It burns more readily than Jet A-1 and is operable in very cool surroundings.

What Is Diesel Fuel?

Diesel fuel is produced to be used in diesel truck engines, car engines and even the ship engine. It, just like jet fuel, is a product of oil that has undergone a refining process. However, diesel possesses other characteristics, which makes it more suitable in ground vehicles.

The diesel fuel is thicker as compared to jet fuel and is also more lubricating. This assists diesel engines to run smooth and longevity-increased. There is also more energy content per gallon of the fuel.

Key Differences Between Jet A and Diesel

Engine Design

Diesel engines operate differently using jet engines. Jet engines are engines which turn quickly and generate thrust. Diesel engines incorporate the use of pistons which move up and down in order to rotate wheels.

Lubrication Properties

Compared to Jet fuel, diesel fuel is extremely slippery. Diesel motors require such additional lubrication to safeguard their fuel pumps and injections. Jet fuel is “dry” and would cause wear in diesel engine parts over time.

Viscosity and Flow

Both fuels can be made thick or thin, but they’re designed for different purposes. Jet fuel has free flowing abilities at high altitude conditions and cold temperatures. Diesel fuel is thicker to lubricate the parts of the engines.

Cetane Rating

The cetane number demonstrates the combustion ability of diesel fuel. The greater the cetane the better the engine performance. Jet fuel doesn’t need this rating since jet engines work differently.

Can You Use Jet Fuel in Diesel Engines?

Yes, but it’s not ideal for long-term use. There are airports which use jet fuel in ground buses and trucks. This saves money since they don’t need separate fuel stations.

Problems may however arise when jet fuel is used in diesel engines:

• The parts of the fuel system are wearing out faster.
• Disgruntled engine life
• Increased costs of maintenance
• The moving parts are not well lubricated.

Can Diesel Power Aircraft?

Diesel can run some small planes, but it’s rare in commercial aviation. The principal problems are:

Weight Problems

Compared to the jet engines, diesel engines are very heavy. More weight will imply less cargo carrying space and a surplus amount of fuel spendings. This renders diesel engines inefficient to airlines.

Power Output

The diesel engines are less powerful compared to jet engines. This puts restriction on the speed and altitude at which planes can travel.

Historical Use

Prior to world war II there were aircrafts which had diesel engines. They were safer since diesel doesn’t catch fire as easily as gas. They had fewer requirements of fuel and less maintenance as well. However diesel engines could not be used in aircraft as jet technology advanced.

Safety and Environmental Factors

Fire Risk

Jet fuel cannot easily blow up as gasoline does, but it is more dangerous than diesel. Diesel fuel is safer to store and handle as compared to gasoline since it has a higher flash point.

Environmental Impact

Both fuels have emissions when it burns. Alternatives are the newer bio-diesel that involves using plant oils, which are less polluting. Sustainable aviation fuel made of renewable sources is also considered by the research of jet fuel.

Storage and Handling

Jet fuel has to be specially stored so as to keep it free of contamination and static strains. Diesel fuel is even easier to store although dry, clean conditions are also required.

Cost Comparison

Several reasons why Jet A usually costs more than the diesel fuel:

• Higher quality criteria
• Special process of refining
• Small production plant
• Cost of transportation go upwards
• Regulations in aviation industry

The difference in price may change according to the place and the situation in the market. Airports tend to take up high prices because of specialized delivery.

Conclusion

Jet A fuel and diesel though with similar origin are used differently. Modern aircraft are powered with Jet A because of its lightweight and clean burning characteristics. Diesel is the fuel that is used to power the land vehicles due to its high lubricity and energy content. Although they may at times replace each other, each type of fuel has its best designed application. The knowledge of such differences would aid in making intelligent fuel decisions based on a given engine use.
