Combustion Process in a Spark Ignition Engine: Analysis of Cyclic Maximum Pressure and Peak Pressure Angle [PDF]
arXiv, 2006 In this paper we analyze the cycle-to-cycle variations of maximum pressure $p_{max}$ and peak pressure angle $\alpha_{pmax}$ in a four-cylinder spark ignition engine. We examine the experimental time series of $p_{max}$ and $\alpha_{pmax}$ for three different spark advance angles. Using standard statistical techniques such as return maps and histograms

Spark Ignition of a Fuel Spray
Transactions of the Japan Society of Mechanical Engineers, 1960 Spark ignition of a fuel spray injected into the atmosphere from a Pintle nozzle has been studied, and it has been found that the ignitibility decreases almost linearly with the time after the end of injection, and that it decreases with increasing distance from the core of the spray cone.

On cycle-to-cycle heat release variations in a simulated spark ignition heat engine [PDF]
arXiv, 2010 The cycle-by-cycle variations in heat release for a simulated spark-ignited engine are analyzed within a turbulent combustion model in terms of some basic parameters: the characteristic length of the unburned eddies entrained within the flame front, a characteristic turbulent speed, and the location of the ignition kernel.
