ABSTRACT:
A detonation control system for a fuel injected, spark ignition two-cycle engine utilizes a linear series of engine knock signals and a programmable microprocessor to provide a non-linear series of stepped increases in the fuel injection pulse width to the engine effective to substantially reduce or eliminate engine knock. If desired or necessary, the system may also be utilized to provide a non-linear series of stepped increases in spark ignition retard to further reduce or eliminate engine knock. The non-linear stepped increases in the control parameters have been found to effectively control detonation without adversely affecting engine performance and efficiency.
