 I spoke extensively with a close friend who is a new product development 

engineer for GM this past summer, and is involved in what you guys speak of in 

gas engines, technically referred to as Homogenous Charge Compression Ignition 

(HCCI).  He claimed it's running now with todays' technology and common 

available fuels E85>93, and mass production is likely 6-10years out using today 

as the benchmark.  His take:  What you will see is a gradual integration of this 

tech eventually evolving into the full HCCI engine, which has several advantages 

to both emissions output and mech/therm efficiency.  It also will eliminate the 

starter from the engine all-together (something BMW has already developed).  I 

would expect Audi/BMW/Mercedes to advance this as well, and Audi is probably 

best experienced to integrate it, based on their tdi experience.



I know having discussed the 2 stroke after-run and Wankel Engine tech in this 

regard with my late father (Senior GM Research Engineer) back in 1979.  At that 

time, the understanding of HCCI was complete, the technology not available.  

Without question it will come to production engines, as the gains in emissions 

is beyond significant.
