I've used an Aussie product called Diesel Fuel Booster made by local company Nulon. It is basically a Cetane booster, like the AMSOIL product, the active component being 2-ethylhexyl nitrate, at 10%-30%. This is the component we need which controls the ignition of our diesel fuel. Previously, when available, the 2% of so of ignition improver was Amyl Nitrate or Isopropyl Nitrate. (Any of those "Nitrates" seem to do the job, but most are now off the market thanks to the junkies). Without it, the engine can be prone to pre-ignite, so the DII smooths out the ignition of the Ether and prevents diesel-knock.
The remaining ingredients are glycol at >10% and Naptha Petroleum at >60%. So, whereas in the old days we used 1.5%-2% "straight" ignition improver, the products of today that contain the important ingredients are virtually all kerosene. If we were to use 2% of a product such as this (or the AMSOIL Cetane booster), then the actual active ingredient we want is at a total of only 0.6%, hardly enough to make any difference.
For those using these "truck" diesel Cetane boosters, can I ask, are you using 1.5%-2.5% of the entire product? I figured that if the Nitrate component needs to be at 1.5%-2.5%, then we need a whole lot higher % of the product in our fuel to add enough DII to make the difference needed.
So, I simply factored in the 70%-90% of the remaining ingredients as part of the kerosene, reducing the added kerosene proportionally. At this, I ended up with the correct % of the Nitrate product.
Having said all that, I'm only working through my own theory. I've tried it on several bench runs. Seems to run ok. In flight? I have no idea.
Hope I haven't baffled too many.
Rod.
