WebHowever, an excessively low effective compression ratio causes high unburned HC emissions and fuel consumption. For example, the compression ratio cannot be less than 5:1, as reported by Helmantel and Denbratt (2006). Note that late IVC instead of early IVC has been successfully used in many HCCI engines (e.g., Nevin et al., 2007; He et al., 2008). WebHigher ratios tend to sound less transparent and more obviously processed. Lower ratios are gentler. They cause the compressor to softly control a track’s dynamics. This effect …
