Abstract
The spark-Optimizer is a closed-loop type electronic control
device that continuously corrects the ignition timing; in effect it
re-tunes the engine some ten times every second. In contrast to the
better known pre-programmed controls, the Optimizer is an adaptive
type system, in which the output influences the input. By providing
the correct spark timing all the time, the Optimizer reduces fuel
consumption considerably.
This paper describes the spark-Optimizer in its advanced version
including recent improvements, like biasing. A comparison with
other electronic spark control devices show its superiority in
accuracy, flexibility, simplicity and production costs. Samples of
test results show considerable fuel savings with the Optimizer.
