Experimental investigation of spark assisted auto-ignition combustion in a small two-stroke engine [PDF]

, 2008
The local temperature of the in-cylinder mixture before combustion is critical to enable auto-ignition (AI) in a gasoline engine. Spark assistance is one of the methods to ensure the critical temperature required for auto-ignition. The application of the

Knock Detection in Spark Ignition Engines Base on Complementary Ensemble Empirical Mode Decomposition-Hilbert Transform

Shock and Vibration, 2016
In spark ignition engines, knock onset limits the maximum spark advance. An inaccurate identification of this limit penalises the fuel conversion efficiency.

Stoma‐Shell Nanoarchitecture for Enhanced Plasma Confinement Catalysis in Synthesis of Ethanol from CO2

Advanced Functional Materials, EarlyView.
High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.
