GENERAL DESCRIPTION
ENGINE MECHANICAL11A-2
GENERAL DESCRIPTIONM2112000101162
This model is equipped with a newly developed 4B11
engine. It is a 4-cylinder, double overhead camshaft
(DOHC) engine with a 2.0-L cylinder displacement.
This engine has adopted the following features:
•MIVEC (MITSUBISHI INNOVATIVE VALVE TIM-
ING ELECTRONIC CONTROL SYSTEM) for
both the intake and exhaust valves
•Cylinder block made of an aluminum alloy
•Valve train with direct-acting valve tappets
•Silent timing chain

CRANKSHAFT PULLEY
The pulley is made of cast iron.
The pulley portion has grooves for the V-ribbed belt
(with 6 crests).
The flange portion of the pulley has a timing mark
notch for checking the ignition timing.
A torsion damper has been adopted to reduce the
torsional vibration of the crankshaft, as well as to
dramatically reduce noise and vibration in the
high-speed range.
DRIVE PLATE
The drive plate is made of sheet metal.The drive plate is mounted with 7 bolts.

AUTO-CRUISE CONTROL SYSTEM
ENGINE AND EMISSION CONTROL17-7
FAIL-SAFE FUNCTION
When any of the following conditions are satisfied,
the auto-cruise control system function is stopped
until the system returns to normal. Also, when any of
the conditions are satisfied during the constant
speed driving, the constant speed driving is can
-
celled immediately.
•An abnormality occurs to the auto-cruise control
switch.
•An abnormality occurs to the stoplight switch.
When any of the following conditions are satisfied,
stop the vehicle once and turn the ignition switch to
"LOCK" (OFF). Otherwise, even when the system
returns to normal, the auto-cruise control system
function will continue to be stopped. Also, when any
of the conditions are satisfied during the constant
speed driving, the constant speed driving is can
-
celled immediately.
•ECM abnormality
•TP sensor abnormality
•APP sensor abnormality
.
DIAGNOSIS FUNCTION
•The diagnostic trouble code check is possible
with the "CRUISE" indicator light.
•To facilitate the system check, check the service
data output with the M.U.T.-III.
NOTE: For diagnostic items, service data output
items, and check method, refer to the Service Man
-
ual.

EMISSION CONTROL
ENGINE AND EMISSION CONTROL17-12
EVAPORATIVE EMISSION PURGE SOLENOID
An evaporative emission purge solenoid is installed in the
intake manifold.The evaporative emission purge solenoid con
-
trols the intake volume of fuel vapor gas from the canister. The
evaporative emission purge solenoid is a duty control type
solenoid valve. When current is not passing through the coil,
nipple A is kept airtight and fuel vapor gas cannot be sucked in.
When current passes through the coil, air can pass between
nipple A and B and fuel vapor gas is sucked in. ECM changes
the ON duty ratio according to engine's operating condition to
control the intake volume of fuel vapor gas.
EXHAUST GAS RECIRCULATION (EGR) SYSTEM <California>M2171000300122
When the combustion gas temperature becomes
high, generation of the environment polluting NOx
(nitrogen oxides) increases rapidly. EGR system is
used to decrease the volume of NOx generated.
EGR system re-circulates exhaust gas inside the
intake manifold. It increases specific heat of the com
-
bustion gases and reduces combustion speed to lower the combustion temperature and reduce the
volume of NOx generated. ECM calculates the EGR
introduction volume according to engine operating
conditions and controls the EGR valve opening angle
at optimum. Also, immediately after the ignition
switch ON signal is input, it drives fully closed step
-
per motor and performs initialization.
