Do we really want to produce hydrochloric acid in large quantities?
I understand that the main reason why engines wear is not the rubbing
factor but hydrochloric acid is produced in the normal automotive engine
corroding the bearing surfaces over time. Today's motor oils just about
stop any wear anywhere, the reason why engines can last half a million
miles or so when kept hot all the time. The moment an engine cools and is
stopped, the oil bath stops and hydrochloric acid starts biting.
I have heard of an engine coating (palladium?) which is used to stop the
corrosion.
Anyway that is my contribution.
