Ecocarbu, an economiser

[dedeleco]

The detailed physics of the slightest phenomenon, like pouring a bottle into a container (bubbles), shaking up a pile of sand, is very complex, enough to do hundreds of serious doctoral theses, too, understanding everything in an engine is immense.

It's like a policeman, you must not miss a single clue and therefore watch and listen with great care.

Simply, one air filter was blocking the passage of air and not the other before ???????????????????????????????? ????????

[Funny ”as their 2 products look like those of hypnow ... the magnus exact copy except the name

I installed the Magnus on my 2 cars. Subjectively, I have the impression that the engines are a little more flexible. But if you hope to make your investment profitable by saving fuel, sorry to shatter your dreams ...

1 °) I did not change much in the end on these engines whether they become economical or not (but systematically, air filter, admin hose + large, WITH or magnets)
2) I spent hours modifying a reduced number of parameters on the recalcitrants (length of the admin hose, location of the AVEC, size of the magnets).

Like that, I noticed a greater flexibility of conduct. And I am happy to have chosen the "Do It Yourself" option.

Projethée, do not forget that a modern engine "weighs" the air it admits according to the position of the throttle and the temperature of the air.

The result is of course judged after combustion by the lambda probe, which measures the rate of unburnt oxygen.

If you wrong the air intake in relation to the position of the throttle, it seems normal to me that you had differences on one of the cars.

Hey guys, this is my 5000 th post!

Another thing, for modern injection pumps and injectors, their lubrication with a fuel which has shorter molecules therefore a priori with less lubricating power ...
What will the manufacturers say if the injection farts?
Who will reimburse?

I shouldn't have been clear enough. I made the same type of modification on 4 of my cars plus 2 of those of friends AND I had different results on arrival. Finally two kinds of results in fact; either nothing significant, or an economy flirting with the 10% (I do not consider as convincing if there is less than that of deviation compared to before). So overall, two out of six positive results and not the first time.

For ex-océano, I did not know that the length of the chains of molecules had a relationship with their lubricating power. Almost 100.000 km with one of these cars and never the slightest engine problem.

Personally, I have always switched my cars to Green air filters for two reasons; one by systematically adapting a "more breathable" filter in relation to the engine capacity, two for the green side because washable. This often requires changing the diameter of part of the intake. But even having carried out these same modifications on two engines of a similar design age (multipoint injection, 16 valves, etc.), one gave very good results and the other none. No matter how much I turned the problem around, I couldn't determine a logical relationship between successful trial and failure.
Yes, I think there is independence between optimization and economizer even if the two have to interact. The engine changes noise after fitting the Green filter (generally a little bit louder), then changes its tone, especially at a speed which must be related to the number and shape of the fins of the AVEC (much rougher, a little like a prepared mill) when it works as it should. This regime also corresponds to the maximum efficiency and coup de pot for me, not too badly placed, between 3000/3500 RPM. And I never touched the exhaust on any of my cars.

On my R19 Diesel, I have already tested it by mounting a heating radiator upstream of the air filter, + a little further a choke throttle recovered on a petrol engine carburetor. This butterfly I closed with a ladle to 3/4 to have a pseudo absolute depression of 0.95 bar at 90 km / h in the intake manifold ...... Well, despite all this additional pressure drop (hot air braked in the radiator + throttle valve), I was not able to see a difference in consumption and behavior on the vehicle over hundreds of kilometers !!!

To the question "Is a lambda air filter better than the original one?" , the answer is that the difference is insignificant on atmospheric Diesel.

On a gasoline engine, normally as long as one is not in the exaggeration for the clogging of the air filter, the regulation with the lambda probe must make the phenomenon transparent in tourism use.

This often requires changing the diameter of part of the intake.

Changing the diameter of the intake ducts changes the attenuated frequency of the assembly (duct / air filter capacity), it is this variation that you hear.
