4-1. CARBURETOR
GENERAL DESCRIPTION
General
This 2-barrel downdraft type carburetor has
primary and secondary systems.
The primary system operates under normal
driving condition, and the secondary system
operates under high speed-high load driving
condition. The choke valve is provided in the
primary system.
The main components and their functions are as
follows.
The primary system has; (1) a mixture control
solenoid valve which is operated by the electri-
cal signals from the Electronic Control
Module (ECM) so as to maintain the optimum
air fuel ratio of the primary slow and the pri-
mary main systems at all times, (2) a fuel cut
solenoid valve which is for the fuel cut under
deceleration and prevention of the dieseling,
and (3) an acceleration pump system.
The secondary system has a secondary diaph-
ragm which is operated by the vacuum from
the primary side and actuates the secondary
throttle valve.
The choke system is a full automatic type
using a thermo-wax.
The switch vent solenoid valve provided on
top of the float chamber is to reduce the
evaporative emissions.
