Abstract
A method and system for operating an engine includes operating the engine with a first plurality of parameters associated with a first fuel type, comparing a detonation signal a first to a first voltage threshold, forming a plurality of vectors by storing detonation signal values that exceed the first voltage threshold, in vectors as vector values wherein later in time vectors include previous vector values, summing vector values for each vector to form a plurality of sum values and when one of the plurality of sums values exceeds a sum threshold, changing an engine controller to operate with a second plurality of parameters associated with a second fuel type.
