Abstract: Low-temperature combustion in reciprocating engines appears to be a cutting-edge technology which ensures extremely low emissions of nitrogen oxides and particulate matters in parallel with high fuel efficiency. This mode of combustion can be realized in homogeneous charge compression ignition engines. However, this technology poses challenges, and fast response combustion controllability is one of the issues to be solved to make this concept widely applicable. The introduction of direct injection of gasoline into recompressed residuals during negative valve overlap is one of the promising techniques to keep the advantages of having a homogeneous mixture during the main combustion while adding controllability through split ratio and injection timing within the recompression event.
