SAAB variable compression, WAS: Flame on

[Richard M]

Also very interesting in a similar vein is the Mayflower development of
variable CR and swept volume. An adjustable link is added between the conrod
and crank pin which can adjust the effective conrod length. Reported in
European Automotive Design, November 2001 - "As well as moving horizontally,
the pivot arm can simultaneously move vertically, which has the effect of
changing the CR and/or capacity of the engine while it is running. In this
way, Mayflower's experimental single-cylinder engine can alter its capacity
from 260 to 300cc or its CR from 9:1 to 15:1 in 15mS"
