Electronic Fuel Injection
The electronic fuel injection (EFI) fuel metering system
delivers the correct amount of fuel to the engine under
all operating conditions. The EFI system is controlled
by a microprocessor, and requires no periodic mainte-
nance or adjustment. If operational problems occur,
see your Volvo Penta dealer.
Detonation (Spark Knock)
Detonation, or spark knock, is continually monitored by
the electronic fuel injection (EFI) system. The EFI’s
computer (ECM) will automatically alter spark advance
to help prevent engine damage if knock is detected,
and there will be a slight loss of power.
