I'm working up a theory here folks , so bear with me . We're all taking it in the shorts with this new few when it comes to fuel mileage, that;s a fact.
Now we know that sulfur does not lubricate, but what does sulfur do.....BURN!
What if the reduction in sulfur has changed the point at which the fuel begins to ignite and the rate at which it explodes?
Well, actually. I have pretty good proof that it has. I worked on European diesels for many moons and it just struck me today that we always had two different sets of timing specs, one for north america, one for everyone else.
the Europeans have been getting ULSD for YEARS and they haven't been having the fuel mileage problems.
The Euro specs have always been WAY more advanced than the US specs. I've tried to run cars near the Euro specs before on the 500PPM fuel and they felt like they were about to self destruct from being too far advanced...but I haven't tried it since the ULSD came out.
The big problem I'm having is trying to figure out how to convert the timing figures to be able to translate the amount of advance difference to these engines, as all the cars I'm used to fooling with have Bosh injection systems and they are all static timed by measuring with dial indicators and that doesn't translate directly into degrees of flywheel rotation .
Are there any of you big rig techs out there who fool with the bosh pumps who might have ever got bored and bothered to convert those measurements into flywheel rotation? or know of a reference somewhere?
