Misfire Diagnosis in Spark Ignition Engines

SAE Technical Paper Series, 2002
<div class="htmlview paragraph">The paper deals with the implementation of a diagnosis procedure able to reveal if anomalies in the combustion process of a spark ignition engine appear and then to identify the responsible cylinder.</div> <div class="htmlview paragraph">The procedure, based on the processing of the exhaust pressure ...

Spark ignition engine torque management

Proceedings of the 2003 American Control Conference, 2003., 2004
Presented 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.

Nonlinear control of a spark-ignition engine

IEEE Transactions on Control Systems Technology, 1995
This 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.

Hybrid tracking control for spark-ignition engines

Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002
The 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 ...

Combustion in a spark-ignition engine

Applied Energy, 2000
Abstract 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.
