Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio.
