Operating range, combustion, performance and emissions of an HCCI engine fueled with naphtha

Samet Celebi et al.

Summary: This study experimentally investigated the effects of naphtha on HCCI combustion in an engine, finding that knocking tendency decreased as lambda value increased and more stable combustion was achieved with the addition of naphtha. The addition of naphtha led to delayed HCCI combustion and wider operating range compared to n-heptane.

New MoO3-CeO2-ZrO2 and WO3-CeO2-ZrO2 nanostructured mesoporous aerogel catalysts for the NH3-SCR of NO from diesel engine exhaust

Jihene Arfaoui et al.

Summary: Higher NO-SCR performances can be obtained between 200 and 500 degrees C over the new ternary MoO3-CeO2-ZrO2 and WO3-CeO2-ZrO2 catalysts. Above 90 % NO conversions into essentially N-2 (>= 97 %) are achieved between 350 and 500 degrees C over the most efficient MoO3-CeO2-ZrO2 ternary catalyst.

A comparative study on the performance of partially premixed combustion (PPC), reactivity-controlled compression ignition (RCCI), and RCCI with reverse reactivity stratification (R-RCCI) fueled with gasoline and polyoxymethylene dimethyl ethers (PODEn)

Huiquan Duan et al.

Summary: The study investigated RCCI with reverse reactivity stratification (RRCCI) with gasoline and PODEn as fuels at low and medium loads in a light-duty compression-ignition engine. Results showed that R-RCCI has moderate combustion rate and efficiency, with the highest indicated thermal efficiency (ITE) and significantly lower NOx and soot emissions compared to PPC. R-RCCI also strikes a better balance between premixed combustion and combustion temperature, leading to very low soot emissions at low and medium loads.

Combustion stability control of gasoline compression ignition (GCI) under low-load conditions: A review

Leilei Liu et al.

Summary: Recent years have seen significant developments in high-efficiency and clean engines, with the gasoline compression ignition (GCI) combustion concept being widely considered for its potential to achieve ultra-low emissions while maintaining high thermal efficiency. However, issues such as combustion instability at low loads need to be addressed for GCI combustion to be fully optimized.
