Three-dimensional imaging of fuel tracer planar laser-induced fluorescence in a homogeneous charge compression ignition (HCCI) engine is presented. A high-speed multiple Nd:YAG laser and detection system, in combination with a scanning mirror, are used to collect eight images, with an equidistant separation of 0.5 mm. Three-dimensional isoconcentration surfaces calculated from the data are visu...
This study investigates the effects of intermediate temperature heat release (ITHR) on autoignition reactivity full boiling range gasolines with different octane sensitivity through intake and simulated exhaust gas recirculation (EGR) sweeps in a homogenous charge compression ignition (HCCI) engine. To isolate ITHR effects, low was suppressed use high oxygen mole fraction. For quantification IT...
Low-temperature combustion modes have attracted global attention in recent years, especially the homogeneous charge compression ignition (HCCI) mode. The HCCI produces high-speed combustion, achieving relatively high thermal efficiencies while emitting low NOX and soot. However, due to lack of direct control start one main challenges this type engine is ensure that auto-ignition occurs close to...
