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 ...

Combustion in Spark-ignition Engines
1990Later chapters in this book will discuss the origins of the fluid motions that occur within combustion chambers of spark-ignition engines, the fundamentals of the combustion process itself and some of the mathematical modelling of this process that has been carried out—all essentially looking at combustion from the inside. The aim of this chapter is to

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 ...

Teaching the spark ignition engine
Education + Training, 1971A proper understanding of the principles of the spark ignition engine must include an appreciation of the effect of variation in compression ratio; a practical difficulty in achieving this result has for long been the very high cost of variable compression ratio engines, most of which have been primarily intended for industrial use in oil company ...

High Efficiency Stoichiometric Spark Ignition Engines
SAE Technical Paper Series, 1994<div class="htmlview paragraph">Nowadays most passenger cars are equipped with spark ignition engines with a three way catalyst. Thus, the improvement of fuel consumption of this type of engine represents a very attractive goal. In fact, it may cause a reduction of pollutant emission, and simultaneously, it may give a contribution to the lowering

Nonlinear torque control of a spark-ignited engine
2006 American Control Conference, 2006A nonlinear state space controller for the optimal torque of a spark-ignited engine is proposed. The controller design is based on feedback linearization in combination with pole placement. The resulting controller basically compensates the intake manifold filling dynamics and thus improves tracking performance of torque demand changes generated by the

Parametric Detectors for Knock in Spark Ignition Engines
1990The efficiency of spark ignition engines, the favoured engine of today’s passenger cars, can be improved by an increase of its compression ratio. However, for high compression ratio engines the angle of ignition for minimum fuel consumption lies in a region where knock occurs.
