COLD START CIRCUIT
The cold start circuit provides a richer fuel mixture
to facilitate starting a cold engine. The circuit
operates only when the engine temperature is
below
+35°C (95°F)
and during the cranking
process.
The cold start valve (1) is of the solenoid-operated
type.
The winding of an electro-magnet is fitted
inside the valve. In the "off" position, the
move'able armature of the electromagnet is forced
against a seal by means of a spring. When the
magnet is energised, the armature is pulled away
from the seat and fuel is allowed to flow through
the valve. A special nozzle atomizes the fuel as it
leaves the valve and enters directly into the intake
manifold.
