Nonlinear control of a spark-ignition engine
IEEE Transactions on Control Systems Technology, 1995This paper describes the improvements which can be made to a spark-ignition engine by extensive use of automatic control. Particular emphasis is placed on fast transient phases produced by simultaneous action on the throttle and the electronic fuel injection device.

Spark ignition engine torque management
Proceedings of the 2003 American Control Conference, 2003., 2004Presented in this paper is a robust feedback controller design procedure to regulate the torque of a spark ignition engine equipped with an electronic throttle mass air flow controller. To this end, a system level model of engine torque production is experimentally determined.

Hybrid tracking control for spark-ignition engines
Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002The design of a torque tracking controller for a spark ignition engine is presented. A hybrid model that describes the interacting behavior of the intake manifold, the engine, the power-train and the catalytic converter is illustrated. The proposed control is obtained by: 1) decoupling the control problem into two sub-problems; and 2) relaxing each of ...

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

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.

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

Spark Spectroscopy for Spark Ignition Engine Diagnostics
SAE Technical Paper Series, 1995<div class="htmlview paragraph">The light emissions from a spark discharge were observed by inserting a fibre optic cable through the centre electrode of a spark plug, to investigate the possibility of determining the fuel-air ratio in the spark gap at ignition with spectroscopy.</div> <div class="htmlview paragraph">The total ...

A new ignition model for spark-ignited engine simulations
Parallel Computing, 2001The amount of spark energy deposited into the combustion chamber is key to an optimum ignition as one can end up with misfires when this energy is low or with other undesired effects on engine performance and byproducts when it is high. Experimentally, up to now, no one has been able to correlate the combustion outcome accurately to the spark ...

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.
