INTAKE MANIFOLD RUNNER CONTROL : System Description
SYSTEM DIAGRAM
SYSTEM DESCRIPTION
Intake manifold runner control valve has a valve portion in the intake passage of each cylinder.
While idling and during low engine coolant temperature, the intake manifold runner control valve closes. Thus the velocity of the air in the intake passage increases, promoting the vaporization of the fuel and producing a intake manifold runner in the combustion chamber.
Because of this operation, this system tends to increase the burning speed of the gas mixture, improve exhaust emission, and increase the stability in running conditions.
Also, except when idling and during low engine coolant temperature, this system opens the intake manifold runner control valve.
In this condition, this system tends to increase power by improving intake efficiency via reduction of intake flow resistance.
The intake manifold runner control valve is operated by the ECM.
Using the system
The NISSAN Voice Recognition system allows
hands-free operation of the Bluetooth® Phone
System.
If the vehicle is in motion, some commands may
not be available so full attention may be given to
vehicle operation.
Initialization
When the ignition switch is placed in the ON
position, NISSAN ...
Recommended fluids/lubricants and capacities
The following are approximate capacities. The actual refill capacities may
be slightly different. When refilling, follow the procedure
described in the “Maintenance and do-it-yourself” section to determine the
proper refill capacity.
