Evaluation of the Potential Benefits of an Automotive, Gasoline, 2-Stroke Engine

Sensitivity analysis and validation of a predictive procedure for high and low-temperature ignition delays under engine conditions for n -dodecane using a Rapid Compression-Expansion Machine

“…Quenching effects near the walls are less relevant when an autoignition occurs, resulting in a higher combustion efficiency, while the maximum local in-cylinder temperature reached in the cycle is also reduced due to the absence of a flame front, resulting in a lower NO x generation by the thermal way. Finally, since in autoignition modes the start of combustion does not depend on the local conditions near the spark plug, lower cycle-to-cycle dispersion is usually obtained under affordable engine loads [3].…”

Correlations for the ignition characteristics of six different fuels and their application to predict ignition delays under transient thermodynamic conditions

“…Autoignition is a combustion mode with high relevance in propulsive systems for transport media and, more specifically, in reciprocating internal combustion engines. Standard Diesel CI-engines base their start of combustion on the autoignition of a fuel spray, while autoignition is an undesirable combustion mode in SI-engines, resulting in unacceptable pressures rise rates that can damage the engine [1]. Furthermore, most of the new advanced Low Temperature Combustion (LTC) modes are based on autoignition [2].…”
