Spark ignition engines

1985
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 ...

The Prediction of Auto Ignition in a Spark-Ignited Engine

SAE Technical Paper Series, 1984
<div class="htmlview paragraph">A constant volume combustion simulation has been used to compute the ignition delays of pure fuels and binary fuel mixtures in air. Minima in the ignition delays were predicted by a comprehensive chemical kinetic mechanism for binary fuel mixtures with methane.

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

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 ...

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 ...

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

Ignition Enhancement in a Two-Stroke Spark-Ignition Engine

SAE Technical Paper Series, 1995
<div class="htmlview paragraph">Conventional two-stroke spark-ignition (SI) engines have difficulty meeting the ignition requirements of lean fuel-air mixtures and high compression ratios, due to their breaker-operated, magneto-coil ignition systems.
