Jet fuels are actually similar to diesel fuel and can be run in diesel engines. But with conventional gasoline engines long having dominated the GA market, few aircraft manufacturers have developed light aircraft with diesel powerplants.
Economies of Scale
Jet-A is used in a much higher volume than 100LL. All the jet engine commercial aircraft each day burn through orders of magnitude more Jet-A than piston aircraft burn through 100LL. That means that there is a much higher production volume, and therefore a cost savings as a result.
But it is lighter than diesel while remaining heavier than gasoline. It is the most widely used aviation fuel.
Kerosene is a light refined product (C6-C16) that has a lower boiling point range than diesel/No. 2 fuel oils. Jet-A (freeze point of -40°C) and Jet-A1 (freeze point of -47°C) are highly refined kerosene-type fuels used in commercial and general aviation turbine engines.
Using leaded avgas in a modern car would ruin components such as the catalytic converter. Conversely, Jet-A wouldn't work in a gas engine. It would be like putting diesel fuel in your gas-powered car, it just won't run.
Kerosene is a harsher fuel for your diesel engine, and the lack of lubrication within the fuel can damage your diesel's injector pump unless you add lubricant.
There are still some big differences between diesel and Jet-A. For starters, there's a higher level of sulfur and other additives-including cetane, and the cetane number-in Jet-A than is allowed in your diesel. This could lead to fines and may even damage your engine.
Jet-A is closer to kerosene and Diesel #1. Most modern diesel engines specify Diesel #2. 4. The viscosity specifications for the two fuels is different.
While kerosene can certainly be a hazardous material, there is no danger that your vehicle will catch fire if its gas tank is filled with jet fuel. However, it will stall out, and it can do severe and costly damage to your engine.
Aviation kerosene, also known as QAV, is the fuel that fuels airplanes and helicopters equipped with jet turbines, turboprops or turbo-fans. Its main use is in commercial air transport. Petrobras Aviation Kerosene is produced using streams of atmospheric distillation and conversion processes, followed by treatment.
The sharp increase in jet fuel prices will increase the operating costs of Indian carriers at a time when they are still struggling to reboot operations after a two-month halt due to the coronavirus pandemic. The fuel cost for an aeroplane is ₹39.06 a litre.
Indian oil companies on Wednesday hiked jet fuel or aviation turbine fuel (ATF) price to Rs 1.12 lakh per kilolitre from Rs 1.08 lakh per kilolitre in Delhi for domestic airlines.
Jet-A smells like kerosene (not quite "like diesel", but definitely not like gasoline). If you are familiar with how both smell you can tell them apart by odor, and a significant contamination of Avgas with Jet-A could be detected by smell.
Unlike gasoline prices, demand for air travel changes by season, and hence the price variation is typically seasonal. Summer air travel generally drives jet fuel prices higher. With a forecasted increase in price, airlines tend to hedge against the fluctuating price of crude oil.
Considering the high torque performance of diesel combustion engines, diesel fuel is clearly the optimal energy carrier for the Army's ground vehicle platforms, from the perspective of both the total powertrain mass (energy carrier + conversion device), and stored energy volume.
Engine Weight considerations:
The diesel engine mount will most probably also be heavier than one needed for a gasoline engine. This increased total engine weight over a gasoline engine means proportionally decreased payload for the aircraft they are installed into.
The most common and reliable type of avgas is 100 octane Low Lead, also known as 100LL. This leaded fuel contains tetra-ethyl-lead (TEL), which is an additive used to prevent engine damage at higher power settings.
Jet fuel is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is clear to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1 which are produced to a standardised international specification.
Kerosene is closer to diesel fuel and is less refined. It can withstand higher temperatures before it vaporizes. This means combustion is not as easy as it is with gasoline. Therefore kerosene is not used a fuel for automobiles.
What makes jet fuel explosive? The liquid fuel is not explosive by itself. Explosive conditions are created when the fuel evaporates and mixes with the air in a partially empty tank.
A jet engine can theoretically run on diesel but this is not done in aircraft. This is because diesel is viscous and it thus has the potential of solidifying at the high altitudes at which airplanes fly. Kerosene which is less viscous is the preferred fuel for jet engines.
Kerosene is also called #1 diesel fuel oil, whereas regular diesel is designated as #2 diesel fuel oil. Some people consider it similar enough that they may try to use it interchangeably with regular (#2) diesel fuel.
It is a common practice for diesel fuel to be blended with kerosene to improve performance characteristics (particularly during cold weather), or other substances, such as used oil to dispose of waste products.
