since it is not expensive, you can give it a try for the kind of saving it can give you..

=O ME 262

yes yes alcoholwater injection is er/was most certainly for keeping control on the Heat in those Heat engines. prevention of preignition is just a good plus for us low octane fuel guzzling, maintenance cost conscious individuals.

They are in use in large capacity beam engines currently? Advances in bore, piston casting/forming procedures and cost effective precision machining and advances in oil and coolant technologies have most certainly spelt doom for the World War Vet Tech.

But still maybe it could help in improve efficiency and thereby power in those Lean burn type engines, like the RE Avls? Can't it be used to extract more out of the fuel, the entrophy of the products of combustion would be different and maybe that can be used to further improve the efficiency of the engine.

It is a sad reality where opportunistic people are taking these unproven sources and selling it using outrageous claims.

^ sir with respect, you have posted the wrong video.

Magnets , 'special' carb, acetone - hmm that i have thoughts reserved on and they are not about increasing fuel efficiency.

The point that we are trying to ascertain is not whether we should make the backseat of your cars a chemistry lab.

It is to ascertain the viability of alternate fuel sources, At the end of that video you will see that the carb motor did run on Hydrogen. and in the second attempt the combustion escaped out. Hydrogen doesnt burn, it Combusts, and it needs oxygen to support that, (Some thing that i remember from my 9th std chemistry books)

Now we can ascertain how to better use the fuel, Brown's gas can be an alternative fuel but, key issues will need to be addressed.

1)commercial generation - fields of solar cells running electrolysis plants using sea water as electrolyte.?

2)storage - no idea, i am a person who likes fireworks

3)fuel control/treatment - how much energy will be released? stoichiometric ratio of brown's gas is 1:2? even then extra oxygen will be needed (how much? dunno), also some nitrogen to control the combustion?

4)usage - i don't know again, conventional 2t engines, maybe some EC engines? how much of the energy released can be utilised?

Once we start addressing the viability of the fuel, the path ahead will be known.

I was referring to the Junker Special fighters...These fighters had cylinders of Nos fitted to be injected into engine ..At high altitude the air is very thin and low on Oxygen, and so to climb to higher Level you need more power from the engine..The Nazis found that by injecting Nos this can be done...So fighters of Nazi Germany would climb higher and faster, and then dive on the un suspecting Allied bombers to make massive killing..
Since Nos makes us laugh, the Junkers fitted with them were called " Ha Ha" fighters.....and of course now Nos is used even in RC Aircrafts and cars.
We use inventions of Nazi Germany even to-day, and some of the greatest inventors and Scientists came from them....If the war had prolonged another month , the end would have been different..

Funny thing is while i was typing those lines in that post, I had a thought that suggested that Nos could have been a good alternative to control the lean burning and absorb the heat excess.

I didnt know that these were employed in the Junkers, Shows how much i have left to learn.

Burst hp was the key then. when viewing the specs of WW2 planes, some fighters had two power specs, like "2300hp and max hp of 2450 for some duration". At that time of reading i had thought that maybe that is achieved with temporarily bumping the supercharge boost, by gearing (or something similar) and sustained max hp running might cause immediate harm to the engine.. and now Nos was also in that picture.! makes me dizzy imagining the quality control they must have practiced.

Talking about Nos, its good for volatile fuels. Is Compressed Oxygen used similarly for diesel engines to improve the efficiency? i know the increase in efficiency could be a subject to debate along with the 'storage of liquified oxygen issue'. But even then is such an approach being looked at?

Inventions during Hitler's Germany were many and Fantastic...beyond comprehension...from jets, to Rockets to Atomic bomb, ..and from cloning to human control with infra sound...you name it, and the Germans were at it....I still continue to read on the German's open and also secret experiments,and find something new each time...
Practical and simple to use additives and fixes only find usage in everyday life...So in Diesel, the steps had been Good quality diesel , Injectors,Turbo/super chargers,EGR,Low Sulphor diesel, and Bio-Diesel...
In Petrol It is Good quality Petrol, Higher Ron,Injectors,Turbo/Super Charger, NOS injection ....all others have repeatedly come and gone due to being impractical/non functional as claimed...

Is there interest in human flight and it's inventions ?

where do you find them?

Yes but the practical and easier solution, is for the common human who doesnt want to experiment. At one point in their life these practical solutions must have been considered impractical?

Theoretically what if the storage solutions are available, and the compressed oxygen is used in a Diesel engine. Instead of needing excess Air the oxygen could be introduced and then some(for constant continuous running). Or maybe the Air can be controlled more aggressively with compressed Oxygen being used in a larger quantity. What could be the implications? (emissions and world health ignored.)

EGR- uhm exahust gas recirculation.. people so afraid of the weather. For better emission control they are trading off capacity to do work. But then agreed, most commercial diesels, in cars will not be working at their peak anyways. But are they for constant speed low rpm, generator running diesel engines?

You mentioned Good quality diesel and Low Sulphor diesel, i was wondering whether this was a typo? or is there more to this?

And Sir, your question regarding interest in human flight and inventions. Ans -> Yes. WW2 fighters!!

Any Hydro Carbon has many chemicals to make it what it is.... Petrol of yester years was not the same as now,and it applies to Diesel too..The sulphar content in diesel gives it smooth engine,but comes out as toxic particulate material once it is burned. Hence sulphar content in diesel is being regulated now....another problem for diesel quality is adulteration with kerosene..Diesel engine can run on Kerosene also ,and so adulteration is wide spread....
Did you know the initial Aircrafts were all fitted with car's in line engines and the crankshaft was directly connected to the propeller?

Guess those engines needed frequent overhauls.
History of flight must have been like seeing a baby grow into an adult, one obstacle crossed after another, Must have been fascinating for the people of that time.

And thanks for clarifying my doubt regarding the diesel, for a moment I had forgotten that we live in a cut throat world.

Waiting for your reply regarding EGR's use in electricity generation diesels.

And the theoretical thing.

EGR is Exhaust gas recirculation...It is done to reduce ICE engine's pollution,and employed mostly in cars and trucks.It is meant to reduce the Nox emission.EGR works by recirculating a portion of an engine's exhaust back to the engine . In a gasoline engine, this inert exhaust displaces the amount of combustible matter in the cylinder. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture.Because NOx forms primarily when a mixture of nitrogen and oxygen is subjected to high temperature, the lower combustion chamber temperatures caused by EGR reduces the amount of NOx the combustion generates.
EGR will be allowed to work only at lower load, less throttle condition,since EGR effectively reduces efficiency at higher RPMs, and under heavy load conditions.

Wow!! What a thread. 'The' most informative, brief & to the point.
Thanks a lot psr sir for sharing all this
wanted to know, what type of (secondary) safety measures our Indian Railways have? I mean anything like ABS, Traction control (to prevent de-railing), crumple zones, buffers etc.
And what other advancements are there in the safety department?

Will there be any decrease in bore-piston life due re-circulation of the soot particles back into the combustion chamber ?

I had cleaned the intake manifold recently and I was surprised to see the amount of soot in the manifold after 90,000 kms.

I have observed in my Tata Indigo and other diesels that EGR gets disabled as soon as the AC is switched on or if the ECU senses that there is sudden depression of accelerator paddle(for sudden demand of power for overtaking etc...).
If the coolant temperature is at 93c and RPM is more than 1200 RPM EGR gets enabled.

Is it advisable to disable the EGR on high mileage engines ?

Safety measures are plenty, just that Humans over ride it.
1. No train should be allowed on same track if there is another train ,either stopped at station or is in movement..The distance considered to be safe for allowing One train behind another is TWO stations....and both stations should be informed, and information acknowledged by the stations,and allowed.
2. No train will be allowed to depart from any station without the "LV" (Last van)board at the rear of the last coach of the train.If any train is seen on any way side station , to pass without this board, the train signal will be blocked and train stopped from proceeding further..If this happens, then the previous station, and the next station are to be informed to stop all trains on the track, and investigate the missing coach position on the track...
3. A token / key to unlock the manned gate near any station will remain with the previous station...Any passing train driver will pick it up on the move and pass to the next station ,and only after that the level crossing gate can be opened.
4. No train will be allowed to proceed without the RED danger Light at the end of Train at the back of "LV".
5. Where tracks are changed/repaired,and Threat to track is present, only after the track inspection staff positioned along the line give the consent, the driver shall move the train forward...even in the night this is followed, and track inspection staff give their OK by blowing the whistle given to them, as the train pass.
6. All standard signals are interlocked..ie., no two trains will be allowed on same track at same time without following the two station rule...if inter locking fails and detected, all trains in the sector are stopped till fault corrected or alternate arrangement as per rule is made.
7. All stations have an entrance and exit cabin at the outer of station, mostly called the "north, and South cabins" . These cabins are the control center for the Line and Signal switching for trains passing through the station..If a Loco driver does not see a Green flag waved by the cabin crew , he must stop the train...similarly if the cabin crew does not see the driver &guard acknowledging their signal, the signal at the station outer will be turned to red.
8. All coaches have crumple zones at the end of the coach....it is the Toilet that is designed to crumple and provide safety to the coach.
9. If there is a run away train, due to some reason, then to reduce damage ,that train will be sent to the siding,(most stations have) where the track will end in a crash buffer...
10.The driver and Asst., driver in the leading cab will be looking out for the signal on their line and the driver MUST call out the color of signal he sees after which the Asst., driver will call out...If there is difference in the call out colors between the two,... the driver must immediately stop acceleration,reduce speed,and try to see, and callout ,and the procedure is repeated...If again there is difference, the train will be halted and signals verified.The same applies to the caution boards, warning drivers of the slope gradient, track work and MOST IMPORTANTLY THE SPEED ALLOWED on that particular track...
11. Any breakdown of train or Loco on the Track must be immediately informed to the nearest station master by the Driver and Guard.

Other safety measures like collision avoidance system, AUTO Brake application,on tripping a red Signal,speed limiter,etc., have all been proposed and not taken up..
EGR is for Pollution control only and in no way improves engine performance...It works only during light load condition and disabled during higher loads, because the system robs the engine of power, and under higher loads, the engine requires all the power it can make.

During Mr.Lallu Prasad's tenure as the railway minister ,the Indian Railways saw many improvements and modernization was at peak....He had ordered for Stainless Steel coaches for passengers to slowly ease out the conventional coach, and had also put in place the plan to fit Disc Brakes in all passenger coaches and Locomotives...A few Stainless steel coaches with Disc brakes were made before election, and after the election the entire program had been put on hold, and Indian Railways is now back to making Losses,as per Ministry....
