What's new

48 F-35s and F-16s conduct elephant walk in Alaska

We replaced DEF (We called AdBlue) in Australia. With a new thing that locally made called "AUSBlue"

There are local varieties as well but the supply and manufacturing is what matters.
The US really did/does rely on the Chinese manufacturing chain which is causing a lot of issues. This also comes down to other imports being dependent upon availability of containers, ships to inland trucking and so on.

Lean Supply chains can knock everything out of balance if they go awry
 
Bears are scared of elephants.

In the coming months if the elephants will stage such arrogant walks in South Korea or Japan the bear may bomb them because the elephants have been arming the UkroNazis to kill the bears.

Well, we did have an DEF shortage back in 2019/2020 (Before COVID) and since China banned Urea export, we sort of made it our own then, it's not hard to shift production line from making fertiliser to making urea, but this is a heavily polluted business. So not much western country are touching it.
 
Hi,

It may look menacing---but it is not in the real sense---.

I just made sense of this news that I recently heard. Most of the fertilizer comes from china and russia---.

And one more thing---most important---DEF fluid comes from china---ie 70% of the US consumption.

You would ask what is DEF fluid---it is

"
Diesel Exhaust Fluid

If you're new to having a diesel truck or heavy equipment, there's a critical additive you need to know about. It's called Diesel Exhaust Fluid (DEF). This additive is also called aqueous urea solution 32% or AUS 32. It's made from 32.5% urea and 67.5% de-ionized water"---.
This fluid is added to all california emission qualifying diesel vehicles and pretty much all heavy duty and medium duty and smaller diesel trucks have to have DEF added to meet clean emissions.

And once the DEF fluid tanks is empty---a warning light comes on and then the engine shuts off.

Only 30 % of DEF fluid is produced in the US by the Flying J trucking fuel stations---the rest comes from china.

DEF---or a lack of DEF fluid is the biggest reason of emission problems in the heavy equipment---. The electronics are designed that the trucks would shut down once the DEF has been consumed.

First the warning light would come on---then the truck would start to lose power---it will start to DE-RATE---end up crawling on the freeway at 5 mph and then ultimately shut off and cost the owner 1000's of dollars in repair.

Can you imagine for east to west coast---line of freightliners, Kenworths, Peterbilts, Volvo, Macks, Internationals---parked on the side of the hwy's---shut down and nowhere to go---because there is no def fluid and the computer has shit down the engine.

So---basically---china can shut down US transportation network . Not a pretty picture


@SQ8 @Irfan Baloch @Hakikat ve Hikmet @niaz sorry I missed to tag many


It is small things that make the difference---. Who would have thought that fertilzer and DEF could create some hurdles.

@WebMaster

@niaz correct me on this information.

To the best my info, all of this started in 2010 when the EPA (Environmental Protection Agency of USA) made it compulsory for all diesel fuel vehicles to be equipped with SCR (Selective Catalytic Reduction) System. SCR technology is not new as I learnt about in an Esso Seminar about diesel engines more than a few decades back.

To put it simply in an SCR equipped vehicle, exhaust gasses from the diesel engine initially pas through a filter to remove soot and unburned particulate matter. The exhaust gasses are susequently passed through the diesel exhaust fluid (DEF) which, as already mention by Honourable Mastan Khan, is made from a very pure Urea dissolved into de-ionised water. Exhaust gases wet with DEF then enter the Catalytic Converter where the polluting oxides of Nitrogen are reduced to the harmless Nitrogen and water.

The above is simplified version of the SCR system but since my field is process engineering, regret to admit that I don’t know much more about it.
