Fuel Injection System FFI1M Combustion Process The FFI 1M combustion process functions in two modes: stratified and homogeneousThe
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: A: mixture is uniform- n chamber Flywheel The FFI 1M flywheel has four The stat The DC
and igni he the voltageside EMM al1grun the and The capacitor is voltage limiterIt prevent fluctuations in voltage that would
cause erratic injector operation, and resultant unwanted changes in fuel mixture and combustion ENGINE MANAGEMENT MODULE
(EMM) The Engine Management Module (EMM) has two engine harness connectorsIt is water cooled microprocessor that receives
inputs from several switches and sensorsThis information is used by the EMM to control engine operating parameters such as
ignition,and fuel injectionEMM inputs include: Throttle Position Air Temperature Crankshaft Position Water Temperature EMM
