Abstract
This paper will explore the knock and emissions control
capabilities of the Lucas Adaptive Ignition System.
A detailed description is given of the operation of the adaptive
knock control together with its integration with efficiency seeking
control. Comparisons are made between the performance of adaptive
and conventional knock control strategies.
Results are presented on the ability of the adaptive ignition
system to control the trade-off between NOx and fuel consumption on
a number of vehicles. Operation on lean burn engines will be
studied with particular reference to the influence of adaptive
ignition on the lean and rich limits of operation.
Suggestions are made on the simplified application strategy for
the adaptive ignition system.
