Implementation of real-time combustion feedback for use in closed-loop combustion control is a technology that has potential to assist in the successful production implementation of advanced diesel combustion modes. Low-temperature, pre-mixed diesel combustion is presently of interest because it offers the ability to lower the engine-out emissions of oxides of nitrogen (NOx) and particulate mat...

This research/article aimed to analyze the influence of an after-treatment system (ATS) on emissions a heavy-duty spark-ignition (HD-SI) engine fueled with liquified petroleum gas (LPG), in context current Euro VI requirements. The ATS is composed by three-way catalyst (TWC) series diesel particle filter (DPF). Emissions testing were carried out test bench according homologation procedures, per...
