Combustion diagnostics in Homogeneous Charge Compression Ignition optical and thermal single cylinder engines
… (HCCI) engine with a negative valve overlap (NVO) strategy. Conventional (pressure-transducer based) measurements and passive optical research have contributed to understanding of the chemical-physical sites of HCCI autoignition and combustion. This experimental work was undertaken on matching …

Effect of market fuel variation and cetane improvers on CAI combustion in a GDI engine
… allowed the use of a split injection strategy involving a pilot injection during negative valve overlap (NVO) recompression, before the main injection during the intake stroke. This strategy, employed at low loads, resulted in heat release during the NVO recompression, which advanced and …

Modelling and diagnostic study of flow in an optical engine with negative valve overlapping for homogeneous charge compression ignition
… induced by using the Negative Valve Overlap (NVO) technique. Case studies for internal nonreactive ‘COLD’ flow structures were investigated using a motored single cylinder optical engine and Particle Image Velocimetry (PIV) technique to validate a 3-D CFD engine model. The optical diagnostics …

Examination of the high load limit of an HCCI engine
… in a HCCI engine using NegativeValve-Overlap (NVO) was varied in the simulation to control the operating point. The engine speed and intake pressure (turbocharged mode) were varied. The High Load Limit (HLL) was attained when the NOx emission reached the regulated level for a …
