Cold start valve (eenail! models)
At cold start, a lot 01 fuel condenses on the cold
surfaces in the form of droplels . Having a separate
cold start valve improves cold starting. It's placed
farther away from the engine block than the ordinary
injectors and delivers the fuel more as a gas than as
drops. The cold slart valve is controlled directly by the
control unit, rather than by the thermal time switch. It
culS in when the temperature is about -15
C (5°F) and when the engine rotation is below approx. 900
rpm.
