http:ReadManm FFI1M FUEL INJECTION Theory FFI 1M Combustion Process The FFI1M combustion process functions in two modes:
is mixed 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 Stratified: AirFuel mixture is layered with
different ratios within the combustion chamberHomogeneous: AirFuel mixture is uniform throughout the combustion chamber Flywheel
The FFI 1M flywheel 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 magnets that work in conjunction with
stator to provide battery charging (12 volts) and injector operation (45 volts)Within approximately one crankshaft revolution,
