"Since ECO-FIRE produces a spark with five times the flow-coupling capability of standard ignitions, the Design News article highlighted the ignition-flow-coupling theory, even though it had yet to be tested. Ignition flow coupling involves placing the spark directly in the fuel mixture flow field of the engine's combustion chamber, in contrast to the more typical approach of sheltering the spark from the flow region by recessing it. CEI's high-energy spark withstands flows up to 20m/sec, says Ward, "so flow becomes an asset when igniting lean fuel mixtures be-cause it stretches the spark kernel, distributing its energy over a larger volume."
In 1977, CEI was formed to pursue lean burn. Initially, it pursued ignition aspects of lean burn and had its first success in 1986 on a Ford Escort at Lucas, England. Under conditions of 20, 35 and 50 percent load, it obtained 25, 17 and 10 percent gain in fuel efficiency at 24:1, 24:1 and 28:1 AFR, with negligible NOx — never seen before in a homogeneous charge engine, reported in the “Economist,” July 5,1986.
................
Five years later, CEI finally received the flow-tunnel from GM. The results were astonishing. GM's HEI had a lean limit of 23:1 to 26:1 AFR. The CEI ignition gave, by comparison, 33:1 to 34:1 AFR, or a hard-to-believe eight AFRs gain. Flow enhanced lean burn, contradicting Exxon's claim. Flow-coupling was seen to be the missing link in lean-burn technology.
