Emission Control System
SystemDescription
The emission control system includes a Three Way Cata-
lytic Convener (TWC), Positive Crankcase Ventilation(PCV) system and Evaporstive Emission {EVAP) Contfol
syst€m. The emission control system is designed to meet
federsl and stats emission standards.

Start the engine. Hold the engine at 3,OOO rpm with
no load (A/T in @ or@ position, M/T in neutral) until
the radiator fan comes on, then let it idle,
Connect a tachometer.
Check and adiust the idle speed, if necessary (sss
page 1 1-95).
Warm up and calibrate the CO meter according to
the meter manutacturer's inst.uctions.
Check idle CO with the headlights, hester blower,
rear window defogger, cooling fan, and air condition-
er otf.
NOTE: (Canada) Pull the parking br8ke lever up.
Stan the engine, then check that the headlights are
off.
CO meter should indicate 0.1 maximum.

Rcgulator Valve
The r€gulator valve maintains a constant hydraulic pressure from the oil pump to the hydraulic control system, whil€
alEo furnishing oil to the lubricating system and torque convener.
Oil flows through B and B'. The oil which enters through B flows thfough the valve orifice to A, pushing the regulator
valve to the right. Acco.ding to the level of hydraulic pressure through B, the position of the valve changes, and the
amount of the oil thlough D from B'thus changes. This operation is continued. thus maintaining the line pressure.

Siator Reaction Hydtaulic Pressure Control
Hydraulic pressure increase, according to torque, is performed by the regulator vslve using stator torque reaction. Thestator shaft is splined to the stator and its a.m end contacts the fegulator spring cap. When the car is accelerating orclimbing (Torque Convener Range). stator torque reaction acts on the stator shalt and the stator shaft arm pushes thersgulator spring cap in this - direction in proportion to the reaction. The spring compresses and the regulator valve movesto increase the regulated control pressure or line pressure. Line pressure is maximum when the stator reaction is maximum.
