Combustion in a spark-ignition engine
Applied Energy, 2000Abstract This paper describes a simple analysis for the prediction of pressure within a spark ignition engine. This is done by modelling the combustion process using the Wieb function approach, which is an exponential function in the form y=1−e−axm, to calculate the rate of fuel burned.

Knock in Spark Ignition Engines
SAE Technical Paper Series, 1981<div class="htmlview paragraph">The knocking characteristics of several fuels are studied using a single cylinder test engine with variations in key engine operating parameters. Compression ratio, spark advance, fuel equivalence ratio, exhaust gas recirculation, engine speed, charge inlet pressure and charge inlet temperature were varied to yield

A Dynamical Instability of Spark-Ignited Engines
Science, 1984A simple model for spark-ignited engines is proposed in which the residual exhaust gases of a combustion event affect ignition of the subsequent charge. The model is an example of a one-dimensional, discrete, nonlinear mapping of an interval. Laminar flame correlations incorporated within models for ignition exhibit Arrhenius kinetics. Small variations

POLLUTANT FORMATION AND CONTROL IN SPARK-IGNITION ENGINES
Symposium (International) on Combustion, 1975The fundamental aspects of pollutant formation and control in spark-ignition engines are reviewed. The pollutants examined are oxides of nitrogen, unburned hydrocarbons and carbon monoxide. The engine concepts discussed are conventional carbureted spark-ignition engines, the Wankel, and different types of stratified charge engines.

This chapter considers how the combustion process is initiated and constrained in spark ignition engines. The air/fuel mixture has to be close to stoichiometric (chemically correct) for satisfactory spark ignition and flame propagation. The equivalence ratio or mixture strength of the air/fuel mixture also affects pollutant emissions, as discussed in ...

Combustion of CNG in Charged Spark Ignition Engines
AIP Conference Proceedings, 2009The paper describes mixing of injected CNG with air and combustion process in spark ignition internal combustion engine. Because of higher ignition temperature of CNG the SI engines have more effective ignition system than conventional engines. The gas motion, turbulence, charge temperature and obviously electrical energy of the ignition coil have a ...

Tomorrow's Spark-Ignition Engine
SAE Technical Paper Series, 1965<div class="htmlview paragraph">This paper deals with the commercial version of the spark-ignition engine. Methods are discussed whereby future engines may be increased in horsepower output and reduced in weight and size. Variable compression methods, charge stratification, fuel injection, and turbocharging are discussed as means of increasing ...
