This paper describes some of the recent work carried out in our laboratory regarding the effects of novel nitrogen compounds in gasoline and diesel fuel on ignition quality and on; study inn chemical structures that can be derived pollutant emissions. Emphasis is given in studying chemical structures that can be derived from biomass (removable raw materials), Our approach was to investigate chemical structures that ran be derived from biomass, by studying the performance of possible gasoline and diesel extenders as gaged by ignition quality, and also by testing their effectiveness in reducing exhaust emissions under various operating conditions.
