IDENTlFtCATION OF METALLIC SODIUM-FILLED EXHAUST VALVE
l Superior he& dissipating .metallic sodium-filled exhaust valves are adopted. During engine operation, the
metalic sodium inside the valve stem melts. As the valve moves up and down, the sodium splashes around
inside the valve and helps to absorb heat from the cylinder head and to transfer it back to the engine
coolant through the valve guide. In this way, the combustion chamber temperature is reduced, reducing
knocking and improving fuel efficeincy.
l Special handling of sodium filled valves is required for personal safety. (See next page.)

13EOF3-31 To prevent vaporlock in the fuel system during hot restart idle, a two-stage pressure regulator is adoped
to the new 323 4WD.
Low temperature operation: The vacuum to the pressure regulator (A and B ports) is cut (solenoid valve
[low temp.] UN), and the fuel injection pressure is increased to 284 kPa (2.90 kgf/cm2, 41 psi ) ,
High temperature operation: The vacuum to the pressure regulator (A port) is cut (solenoid valve [high
temp.] ON), and the fuel injection pressure is increased to 343 kPa [ 3.5 kgf/cm2, 49 psi 1.
