CV-16 Liaoning (001 carrier) Thread II ...News, Views and operations

It is no problem to use kerosene in diesel engines or diesel in jet engines. Kerosene and diesel are quite the same. You can't use gasoline in diesel engines and only for a limited time in some jet engines (Beech King Air turboprop only 200 hours for example).

I don't think so Kerosene is a cut above diesel and burn cleaner I don't think they are interchangeable at least not in jet engine. You can use kerosene in diesel engine

The Diesel Family
In the diesel family we have things like Highway Diesel and the various grades of home heating oil.

For transportation purposes these fuels are used in compression-ignition engines ("diesel engines"), where a high temperature and pressure will cause the fuel to ignite and burn, producing power.
For other purposes (like heating) we basically light the stuff on fire and are happy it burns.

The Kerosene Family
The Kerosene family are close cousins of the Diesels, including K-1 and K-2 Kerosene (obviously) and Jet-A.

Jet-A is a high-purity kerosene based fuel manufactured under a specific ASTM standard (D1655), with specific physical properties, and is used in jet turbine engines. Fuel not meeting the Jet-A specification is generally recycled in the production chain for other purposes (for example it may be used in blending kerosene for heating, or blended into highway diesel).

Jet-A is suited for turbine engines, but can also be burned in other compression-ignition piston engines like diesel can (there are a wide variety of

available from several manufacturers).

Other grades of Kerosene are used for motor fuels, cooking fuel ("camp stove fuel" is typically kerosene) heating, lighting, etc. depending on their refining and purity.

A lot of turbine engines are so called "multi-fuel" engines. One example would be the M1 Abrams tank engine. Which is based on an helicopter engine. The engine might be optimized to run on a certain fuel but it doesn't mean it won't run on some other fuel.
Fighter aircraft typically are more tuned to a certain fuel so they're more finicky about that. Some fighter aircraft engines might have difficulty starting up with the wrong fuel.

The USA typically loads some form of Kerosene on most of it's marine vehicles because it can be shared among nearly every single vehicle in the fleet. Ships, aircraft, and land vehicles. Gasoline vehicles were mostly eliminated from the US Army because of that. You'll even find Diesel powered motorcycles and things like that. The difference between what we typically call Diesel and aviation grade Kerosene is basically one of purity. Aviation grade Kerosene (Jet-A) uses a subset of the hydrocarbons typically found in Diesel fuel. So it's typically more expensive. However typically an engine that runs on one will more or less run with the other. You'll find that a Diesel vehicle will run just fine on Kerosene (it's just more expensive than Diesel), and the opposite is quite often true as well. Especially in things like marine turbine engines.

So, in short, you would typically want to use Diesel on marine turbine engines and land vehicles, because it's more cost effective and only use Kerosene (Jet-A) for the aircraft). However the US Navy and other branches of the US Armed Forces typically just use Kerosene because it simplifies logistics.

I'll give another example. The GE LM2500 marine gas turbine engine:

"Examples of fuel versatility for our gas turbine and package products include:
Gaseous fuel
• Pipeline and liquefied natural gas (LNG)
• Syngas (low and medium BTU)
• Propane, high hydrocarbon gas
• Wellhead, associated gas
• Coal bed methane (CBM)
• Landfill gas (LFG)
• Coke oven gas (COG)
• Refinery/process flare gas
• LNG for marine propulsion

Liquid fuel
• #2 Diesel
• Jet fuel, kerosene
• Naphtha
• Biodiesel
• Ethanol
• Liquid blends
• Butane"

Someone was asking about a list or map of Liaoning's deployments, this is from the 2018 Pentagon's report to the Congress on China, page 44.

They patrol their shores up and down. Truly no task for which you construct aircraft carriers.

Training is not the same thing as patrolling.

 

[Sczepan]

and every time they went to Bohai Sea, to picked up some fighters as I think

Great Tam thanks for that I was wanting to see something like that !

Americans have such a tight eye on Chinese Navy no doubt about it

It seems as if the Liaoning not only receives a new coating of the flight deck but also got some more modifications: the aft aviation bridge was completely removed and changed to a design as installed on the Type 002 carrier.
