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 ...

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

Combustion in Spark-ignition Engines

1990
Later 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

Teaching the spark ignition engine

Education + Training, 1971
A 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 ...

Nonlinear torque control of a spark-ignited engine

2006 American Control Conference, 2006
A 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

Spark Ignition Engine Progress

SAE Technical Paper Series, 1967
<div class="htmlview paragraph">A review of past development progress, the basic engine design problem, and the design status of today's engine indicates that the continued development of the four cycle, reciprocating piston, spark ignition automobile powerplant means continued improvements and the creation of a more difficult task for possible ...

Combustion of CNG in Charged Spark Ignition Engines

AIP Conference Proceedings, 2009
The 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 ...

Parametric Detectors for Knock in Spark Ignition Engines

1990
The 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.

Hydrocarbon Emissions from Spark-Ignition Engines

2009
To contrast the phenomenon of HC formation in a Diesel and a spark ignition engine, a chapter is included on the latter. The absorption and desorption of fuel by cylinder lubricating oil films has been modelled using principles of mass transfer in this Chapter.

Simulation of spark ignition engine

Materials Research Proceedings
Abstract. The internal combustion engine (IC Engine) has found its place in various industries and consumer products, from generators to trucks and cars. They are also one of the most polluting devices developed, hence it is paramount to reduce the emissions from IC engines and to optimize their design to provide maximum performance with the least ...
