Title: Precups
Post by: Kyradawg on March 25, 2010, 06:31:44 pm

I read a patent article the other day talking about ceramic (silicon nitride) Isuzu precups from an early/mid 80's engine being used a chrysler diesel (not sure what) but anyway it was said to increase fuel economy by 4-5% due to less thermal energy loss. Anybody heard about these made by kyocera ceramic cups? Toyota is said to have used them also.

Peace&Love, Darren :)

they have been discussed. but most of us are sticking with the inconel ones. they are there and already work very well.
