Numerical and experimental investigations of the effects of the second injection timing and alcohol-gasoline fuel blends on combustion and emissions of an HCCI-DI engine

An applicable approach to mitigate pressure rise rate in an HCCI engine with negative valve overlap

“…In their HCCI development research Turkcan et al [26,27] studied the effect of DI timing on combustion, engine efficiency and emissions. In this study, fuel injection was split into two portions, with 80% of the fuel was injected early during the intake phase and the remaining 20% was injected directly during the compression stroke.…”

Performance Evaluation of Homogeneous Charge Compression Ignition Combustion Engine – A Review

“…Iso-octane gives the most usable IMEP (indicated mean effective pressure) without supercharging when utilizing a compression ratio of 17. Still, iso-octane cannot be used at pressure ratio higher than 19, because of early combustion initiation [28,[73][74][75]. To achieve the maximum advantage of HCCI mode, the compression ratio should be between 8 and 16.…”

Numerical simulation of a heavy-duty diesel engine to evaluate the effect of fuel injection duration on engine performance and emission

“…In this regard, control of combustion start and ignition delay should be well analyzed. Turkan et al [19] studied the fuel injection time in a diesel engine. They showed that injection time is a parameter that directly affects engine performance and emissions.…”
