Variable compression systems for future engines and fuels /

Variable Compression Systems for Future Engines and Fuels explores variable compression ratio (VCR): one of the most promising--and historically elusive--advancements in internal combustion engine (ICE) technology. Long recognized for its thermodynamic benefits, VCR has challenged engineers for deca...
