Description

INFOID:0000000011278206

FUEL CUT CONTROL (AT NO LOAD AND HIGH ENGINE SPEED)

If the engine speed is above 1,800 rpm under no load (for example, the selector lever position is neutral and

engine speed is over 1,800 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off var-

ies based on engine speed.

Fuel cut will be operated until the engine speed reaches 1,500 rpm, then fuel cut will be cancelled.

NOTE:

This function is different from deceleration control listed under Multiport Fuel Injection (MFI) System, 

EC-37,

"MULTIPORT FUEL INJECTION SYSTEM : System Description (with automatic air conditioner)"

 or 

EC-39,

"MULTIPORT FUEL INJECTION SYSTEM : System Description (with manual air conditioner)"
