What MEFI (Marine Electronic Fuel Injection) Means to the Boater and Family
. More responsive and smoother acceleration is the
result of the MEFI system's. Marine Fuel injection gives you the ability to instantly deliver
an atomized flow of fuel for as long as needed.
. Excellent turnkey starts in all weather conditions are
made possible because the ECM (electronic control module). Marine Fuel injection gives your motor the sense as to whether
the engine is cold from morning chill or hot from
heavy use and then provide the right amount of fuel
for instant starts. This leads to more efficient operation.
. Smooth, reliable idling comes from the ECM's ability
to provide the correct amount of air and fuel during
idling. Fuel injection tuning results in reliable idling, whether the
engine is hot or cold, and no stalling while moving in
and out of gear because the computer reacts to compensate.
. Significantly reduced fuel consumption is due to
the precision of the electronic engine management
system (EMS). Only electrically controlled components, like fuel injectors, provide the precision necessary.
. Improved control of the engine leads to better emissions. Fuel injectors make an engine capable of meeting CARB and EPA emission requirements. A carbureator has no chance under adverse conditions and forces.
. Engine knock control: MEFI utilizes dual flat
response knock sensors, and is capable of sensing
and controlling knock on an individual cylinder
basis. Engine knock control is attained by detecting
engine knock and then virtually eliminating it by
automatically changing the spark timing and fuel
delivery. This means that a tank of less-than-perfect
gasoline will not ruin a boating weekend.
. Speed reduction reduces engine speed if one of the
inputs to the ECM indicates an operating condition
that is out of proper limits. Operating conditions
that cause speed reduction could include engine
overheating, low oil level, and low oil pressure.
. Altitude compensation is a welcome help for boaters
who sometimes vacation in higher altitudes. The
ECM system senses air density and modifies fuel
and spark accordingly.
. Self-diagnostic capabilities make for faster, more
accurate maintenance on those rare occasions
when the MEFI system needs servicing.
