Unburned Hydrocarbons in a Spark-Ignition Engine Cylinder
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1984 C3H8-O2-N2 mixtures were spark-ignited in a motored engine cylinder, and the mass fractions of CO2, CO, H2 and hydrocarbons in the cylinder during the exhaust process were investigated. In the vicinity of the limits of flame propagation in the engine cylinder, branched flames, which propagate at relatively slow speed, appear. In the mixture composition

Knock Reduction of Spark-Ignition Engines by EGR
SAE Technical Paper Series, 1986 <div class="htmlview paragraph">In order to reduce the knock of spark-ignition engines in the heavy load region, the effects of EGR on engine performance were investigated on two engines, one with a turbocharger and the other naturally aspirated with a high compression ratio.</div> <div class="htmlview paragraph">It was found that EGR

Effect of biofuel E85 combustion on fuel consumption in spark-ignition engines
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012 Biofuels represent an alternative source of energy that should gradually decrease our dependence on crude oil. A rapid development of their use in combustion engines is above all the consequence of their very positive balance of emissions.

Abnormal combustion - methanol versus gasoline
, 1988 Includes bibliographical references.The maximum efficiency of conventional gasoline engines is largely determined by the compression ratio, and this is limited by the onset of kno8k. The maximum cylinder size is similarly constrained.
