IGNITION TIMING AND CONTROL FOR CURRENT CARRYING TIME
MULTIPORT FUEL SYSTEM (MFI)13A-37
2. Spark-advance control and current carrying
time control
.
[During start]
ECM initiates ignition at fixed ignition timing (5° BTDC) syn-
chronized with the crankshaft position sensor signal.
.
[During normal operation]
After determining the basic spark-advance based on the intake
air volume and engine speed, ECM makes compensations
based on input from various sensors to control the optimum
spark-advance and current carrying time.
List of main compensations for spark-advance control and current carrying time control
.
[Control for checking ignition timing]
During basic ignition timing set mode for M.U.T.-III actuator test
function, sparking is done with fixed ignition timing (5
° BTDC)
synchronized with crankshaft position sensor signal.
CompensationsContent
Intake air temperature compensationCompensation is made according to intake air
temperature. The higher the intake air temperature
the greater the delay in ignition timing.
Engine coolant temperature compensationCompensation is made according to engine coolant
temperature. The lower the engine coolant
temperature the greater the advance in ignition
timing.
Knocking compensationCompensation is made according to generation of
knocking. The greater the knocking the greater the
delay in ignition timing.
Stable idle compensationCompensation is made according to change in idle
speed. In case engine speed becomes lower than
target speed, ignition timing is advanced.
Delay compensation when changing shiftDuring change of shift, sparking is delayed
compared to normal ignition timing to reduce
engine output torque and absorb the shock of the
shift change.
Battery voltage compensationCompensation is made depending on battery
voltage. The lower the battery voltage the greater
the current carrying time and when battery voltage
is high current carrying time is shortened.

MIVEC (Mitsubishi Innovative Valve Timing Electronic Control System)
MULTIPORT FUEL SYSTEM (MFI)13A-40
MIVEC (Mitsubishi Innovative Valve Timing Electronic
Control System)
M2132023500212
MIVEC is the system which continuously varies and
controls the opening and closing timings of the intake
valve and the exhaust valve.
System Configuration Diagram
MIVEC allows the optimum valve timing to be con-
trolled in accordance with the engine operation and
the idling stability to be improved, as well as the out
-
put and the torque to be better in all the operation
ranges.
•The ECM assesses the engine operation through
the signals from each sensor.
•Based on the assessed information, the ECM
sends the duty signal to the intake engine oil con
-
trol valve and exhaust engine oil control valve as
well as controls the spool valve position.
•Changing the spool valve position allows the oil
pressure to be divided into the retarded chamber
and the advanced chamber, as well as allows the
phases of the intake camshaft and the exhaust
camshaft to be continuously changed.

•The interiors are fully covered by trims.
•The energy absorption rib molding located in the
back side of the front pillar trim and the rear pillar
trim protect head from side impacts and the resin
materials for the trims are unbreakable materials.
•Use of nonflammable materials for the trims has
increased safety as outstanding interiors. Also,
material codes are indicated to deal with recy

•The decorated panel has been adopted for the
front door trim.
•The bottle holder for bottles with shapes that are
difficult to keep upright has been adopted for the
front door pocket.
•The front door pocket with a large capacity has
been adopted for items such as A4-size map.
Also, the rear door pocket has been added.
•The shock absorbing arm rest has been adopted
which reduces the mid section injuries to passen

gers by collapsing upon side impact.
•The arm rest which is formed with cloth has been
adopted to create a continuous flow with the
ornament section.
