Synchronous fuel injection
Synchronous fuel injection is fuel injection that occurs using a fixed timing, which is synchronized
with the crankshaft angle set by the engine ECM according to the signals from the pulser coil.
Example: Group fuel injection in the start-up mode

Fuel injection timing
Fuel injection amount
Condition
Simultaneous
fuel injection
in the start-up
mode
All cylinders according to
the fuel injection setting
data
According to the fuel
injection setting data when
the engine temperature is
78–80 °C (172–176 °F) or
more and the fuel injection
setting data when the
engine temperature is less
than 78–80 °C (172–176
°F)
Until cylinder
identification is
completed by the
pulser coil
Group fuel
injection in the
start-up mode
Each cylinder group (#1
and #4, #2 and #5, and #3
and #6) at BTDC 430°
(BTDC 70° according to the
exhaust TDC)
Until engine
starting is detected
(500 r/min or more)
Group fuel
injection in the
normal
operating
mode
Each cylinder group (#1
and #4, #2 and #5, and #3
and #6) according to the
exhaust and compression
TDCs
According to the fuel
injection setting data for the
fuel octane rating and the
knock learning value, which
are recorded in the engine
ECM
Until cylinder
identification is
completed by the
cam position
sensor (PORT EX)
2 times for every 2 turns of
the crankshaft
Sequential
fuel injection
in the normal
operating
mode
Each cylinder according to
the injection completion
timing, which is set using
the exhaust TDC
After cylinder
identification is
completed by the
cam position
sensor (PORT EX)
