Today’s engines can deliver a fuel efficiency of 40-42%, with corresponding loss of initially available fuel energy of 58-60%. The feedback during the 2008 merit review criticized the constant-pressure approach, suggesting that a constant volume approach was more relevant to combustion engines.

(Najt, then at the University of Wisconsin, and David Foster published the first study of a gasoline-fueled four-stroke HCCI engine in 1983.). Then in the Spring of 2008.we Najt said that GM is using its available injection and valve management technologies with thermal and fuel stratification to slow down the burn rate.

To extend HCCI to idle (shown in 2008, earlier post ), GM is using a Multiple Injection and Multiple Ignition (MIMI) strategy, combined with the use of in-cylinder fuel reforming during recompression as a bridge technique up to the classic HCCI operating range. Peak valve lift of intake and exhaust valves was varied based on the strategy.

The first auction for allowances was held on September 25, 2008. Since September 2008, RGGI has raised $583 million for the states in these quarterly auctions of permits with between 65 and 70 percent of cap-and-trade proceeds going back into the clean energy economy. The program then reduces the cap by 2.5 Another six U.S.
