Group,

 As a true motorhead I have been interested in direct injection for the 13B and 20B for some time. There are several common-rail systems becoming available. Things look very interesting for the future!

 The wankel is a natural for HYDROGEN fuel. In fact it is my personal opinion that the Renesis engine was an outgrowth of the work done on the hydrogen fueled engine. The fact that the rotary can be easily set up with NO OVERLAP is the key to preventing backfiring and other problems pistons engines face when running hydrogen. FWIW
