High vs low compression ratio
WebMar 19, 2024 · All things equal, engines with higher compression ratios require higher fuel octane. This is because a lower octane fuel may begin to ignite prior to the initiation of the spark event through … 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).
