Current ridicule

Remembering I am referring back 30 years...

Why would that matter.  At least one of the patents I found was 40 years.

I definitely recall it as being Shell Canada but nonetheless I limited the search to just Shell...

Even so, a google search doesn't mean much if your claim is that there is a Canadian patent.  CIPO tracks those.

This search has 167 hits on just one type of system which I was researching at the time

https://www.google.com/search?tbo=p&tbm=pts&hl=en&q=inassignee:%22Shell+Oil+Co%22#hl=en&q=inassignee%3A%22Shell%22+vaporize+internal+combustion&tbm=pts

Given some time and a little inclination I think I could do better than a quick 5 minute attempt

3987773, 3939813, 3927651 and 3763838 look they are the inventions of Shell USA employees.
3935849 looks like a patent they bought.
2234407 is a 1939 patent.  So, they have a long history of interest in fuel vapor developments.


And on it goes.

I can step in here with a personal account.

The Shell story is NOT an urban myth. It is a fact I can personally testify to after hundreds of hours of research.

In the early eighties I was doing a lot of research into fuel atomisation as part of my developing what I called Viper, "Vapour Injection Power and Economy Regulator". In those days long before the internet you had to spend many hours reading patents and summaries in the actual Patent office. I became very familiar with Melbourne's office.

I looked at heat vapourisation. Sound vapourisation using crystals, atomisation using pressure. different types of combustion chambers designed to vapourise the fuel just prior to ignition. In short I studied dozens if not hundreds of patents.

Without fail 95% of the patents I studied were attributed to Shell Oil of Canada. I surmised at the time that the Canadian office was in charge of buying up EVERY SINGLE fuel saving patent it could get its hands on.

Jokingly I considered patenting devices purely so that Shell would buy them. Over thirty years later I truly wish I had done that. perhaps I would be wealthy now.

But that's history....

i've got to laugh at myself for a minute considering how much of a hard time i was giving you in some message threads and stop now to thank you for validating what i was saying about shell oil.  at least we can agree on that.   thank you.

as far as why fuel injectors and some other fuel saving innovations moved into production i clearly recall the government making requirements back about that time that the car manufacturers had to start making cars with higher mpg.   so i would guess they went with some of the tech cars now have but which could be controlled easily by computer to limit just how much better it could get.  or maybe the limit of how much better mpg it can achieve is inherent in the design.   of course the goals they were told to achieve by certain dates or years have largely been forgotten.  look at what happend to mpg ratings when suv's came about. 

i said i was done with this thread but i had to thank curious chris.   does anyone really think big oil does not have an interest in keeping mpg low.  say aye loudly if you think they have no interest in keeping mpg low.

maybe it is also worth mentioning that some of the ingredients added to gasoline in recent decades are directly responsible for making it much more difficult to turn gasoline into vapor.

Sigh.  The goals were never lost.  SUV's got around CAFE limits and they were appealing to consumers because of CHEAP GAS.  Engine improvements from 1985 to at least 2000 went into making bigger, heavier, faster accelerating cars that consumers ate up.  Now, we finally have new regulations in place that are again raising CAFE limits and now include SUVs.

Are you aware where big oil makes most of its money?  It is not in the refining and distribution.  It is in exploration and production.  Asian demand assures growing consumption even if the US stopped consuming all gasoline tomorrow.
