Diesel fuel cold starting additives

Slide presentation to diesel-fuel industry group, convened by
Advanced Engine Technology, Ltd., (AET), Ottawa, 18th April, 2005

NOTE: Readers unfamiliar with the definition of Cetane Number can read the first few pages of the Introduction below
(much of the remainder of that account, dated 1993, is now of little relevance as it deals mainly with sulphur-containing fuels,
and not with the low-sulphur fuels now used in North America).

Note also that in the intervening years, the steel-bomb method (paragraph 2 of Section 2, page 4, of the Introduction) for measuring diesel-fuel ignition quality has been developed extensively by AET
[L. N. Allard, G. D. Webster, T. W. Ryan, A. C. Matheaus, G. Baker, A. Beregszaszy, H. Read, K. Mortimer and G. Jones,
"Diesel fuel ignition quality as determined in the Ignition Quality Tester (IQTTM) -- Part IV",
SAE Technical Paper Series, 2001, 2001-01-3527].
Being much faster and less cumberome than the primary standard ASTM D-613, it is rapidly becoming the method of choice for determining the ignition quality of both conventional and bio-diesel fuels under ASTM-D6890.
