EFI system (500/600cc)
The throttle body control inhalation engine cylinder's air
Volume, thus achieves controls engine's rotational speed
and the load. the throttle body have two channel constit-
-utions, namely main channel and by-pass channel. The
accelerator pedal controls main channel's damper opening
through the accelerator back guy, reduces expenses to enter
engine cylinder's gas flow amount; the damper opening
transmits from the damper position transducer to engine
control unit ECU. Flows through the by-pass canal the gas
flow amount by the unit motor control, meets the system
requirements the idling regime goal rotational speed.
NOTE: The idle speed limit screw does not allow the
adjustment, the engine idle speed depend on the EFI
system adjustment completely, does not hand adjust
