Prelude L4-1958cc SOHC (1988)
Carburetor Solenoid: Description and Operation
Main Air Jet Control System
Fig. 82 Main air jet control system.
This system, used on Prelude, Fig. 82, controls air flow into the main air jets of the carburetor throats in order to maintain optimum air/fuel ratio.
When vehicle is being started, or running in the power mode, the control unit energizes the main air jet solenoid valve in the air cleaner to close the extra
air passage, increasing fuel flow.
