FICHTFUEL INJECTION Theory FFI Combustion Process The FFI "" combustion process functions in two modes: stratified and homogeneousThe
by turbulenceIn this mode the mixture is more combustible, so fewer firings per combustion event will occurVery low amperage
is required to sustain either stratified or homogeneous operation Flywheel The FFIflywheel has four important functions:
Provides ring gear for starter motor engagementHas cast-in timing encoder ribs on the outer diameter that work in conjunction
with the magnetic crankshaft position sensor to control ignition timing and fuel injector operationHouses magnets that work
in conjunction with the stator to provide power to operate the ignition, injectors, EMM, MFI(multi-function instrumentation
gauge), and accessories It contains ceramic magnets that work in conjunction with statorto provide battery charging (12 volts)
and injector operation (45 volts)Within approximately one crankshaft revolution, the EMM will learn crankshaft positioning
