New Trends in Electronic Engine Control - To the Next Stage

This paper reviews new engine control technologies and future trends, particularly in mechanical and electrical engine control components, the application of modern control theory, and new advances in sensor technologies.

A system which utilizes engine cylinder combustion information is representative of these new trends. Like other such sensor systems, the combustion sensor still has problems which must be overcome before practical application is possible.

The factors and problems involved in developing this sensor will be discussed, along with how the relationship between sensing information and engine performance can be used to improve engine performance.
