Crazycanuck Posted February 15, 2008 Share Posted February 15, 2008 I have been thinking about which type of engine to put in my Cozy eventually. Rotary engines are on my short list of choices that I am considering. I just wanted to comment though on the common argument that rotary engines are more reliable because they only have 3 moving parts. At first I felt that this was a good argument, but not so much anymore. The same could be said for 2 stroke engines, as they have only three moving parts at their core (piston, connecting rod, and crank), but they tend not to be nearly as reliable as 4 stroke engines generally speaking. I have a very complex engine in my motorcycle with things like variable valves (VTEC) and its engine is considered one of the more reliable engines out there. So in the end it isn't really the number of parts that determines reliability, rather how carefully those parts were designed for their given purpose. my $0.02 Quote Crazy Canuck Toronto, Ontario, Canada Cozy MKIV #MK1536 Link to comment Share on other sites More sharing options...
