But as usual, in California you eventually may not have a choice which diesel fuel you use if you buy it here. On the other hand, prices here are higher than anywhere else, so truckers might want (and likely do) buy their fuel in a neighboring state, like Nevada, before driving into CA. So far, the inspection stations at the border are not smelling truck exhaust to make sure that is smells like french fries and not oil. But that time might come.

While the military did contribute to primarily large engine development, automobiles including race cars saw the majority of engine development. Superchargers, 4 valve heads, overhead cams and dual spark plugs were first introduced in automotive applications prior to WW1.

Absolutely true, "win on Sunday, sell on Monday." At the bottom, in my opinion most of the significant improvements in engine development have been enthusiast driven.

FWIW I'm a member of the Connecticut Antique Machinery Club, some members have IC engine powered equipment dating back to the 1890's, I'm always amazed at the technology that was employed in some of those early efforts. Unfortunately, it was often sidelined due to cost or manufacturing issues only to be "reinvented" once those issues were resolved.

@ # 227: Auto racing the 1930's was used by Germany and others to develop & showcase their aviation engines. Insanely powerful engines were used to race on tires little better than pencil erasers.

350 J Platform / Revised Service Schedule: J Series Valve Adjustments and 1st Service Kit Updates

« Last Post by indibiker on April 23, 2024, 03:50:27 pm »

Previously, the RE's 1st Periodical Maintenance Schedule (500 km or 45 days) on the J series mandated an inspection and adjustment advice for the inlet and exhaust valve clearance.

The recent update in India indicates a revision to the valve adjustment requirement, extending it to 10,000 kilometers or 1 year, unless there are external factors prompting earlier attention, such as unusual valve noise, etc.

The updated First Service Kit contents have also been modified to exclude the rocker arm cover gasket and its bolt gaskets.

The video confirms the updates: <https://youtu.be/pamwcupfA_U?si=LAKe_Jf4RAaAdnji>

Aluminium! 4000% production increase 1900 - 1954. Now THAT's an increase in production! Once again warfare drives technology...stick...rock...stick with heavy/sharp rock attached(club)...stick throwing another stick (atlatl dart)...atlatl dart guided by bird plumage...stick and string throwing another plumage guided stick (bow)...and now energy weapons.

https://en.wikipedia.org/wiki/History_of_aluminium
Aluminium was difficult to refine and thus uncommon in actual use. Soon after its discovery, the price of aluminium exceeded that of gold. It was reduced only after the initiation of the first industrial production by French chemist Henri Étienne Sainte-Claire Deville in 1856. Aluminium became much more available to the public with the Hall–Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886, and the Bayer process developed by Austrian chemist Carl Joseph Bayer in 1889. These processes have been used for aluminium production up to the present.

The introduction of these methods for the mass production of aluminium led to extensive use of the light, corrosion-resistant metal in industry and everyday life. Aluminium began to be used in engineering and construction. In World Wars I and II, aluminium was a crucial strategic resource for aviation. World production of the metal grew from 6,800 metric tons in 1900 to 2,810,000 metric tons in 1954, when aluminium became the most produced non-ferrous metal, surpassing copper.

Good point, very many significant improvements to the IC engine were driven first by military necessity, think innovations in WWI and WWII aircraft engines, before making their way into general use. Of course, so was Tang, but that's another issue.

Improved machinery for accurately boring cannon barrels also allowed the production of better quality cylinders for early steam engines. Not everything from the military-industrial complex is for destruction and bloody piles of corpses, we get some essential things and fun stuff too.

I suggest it's a bit of both.

I agree with beanbean50 no misfires since fitting FuelX lite, I think ecu must lean the fuel off to a point where it shuts off !
