Intake Air System
Intake Manifold Runnner Control (IMRC)
The IMRC valve is designed for stable combustion in low speed range by opening and closing the IMRC valve. The IMRC valve opens and closes producing the gap of the flow rate between the swirl port and the secondary port, and thereby it controls the swirl volume.
Intake Manifold Runnner Control (IMRC) Position Sensor
The IMRC position sensor detects the IMRC valve angle.
Turbo Boost Charger
The variable nozzle type turbo charger is adopted on this model.
It controls the back pressure and supercharged pressure in optimum balance for the engine speed and load by opening and closing the variable nozzle located on the circumference of the turbine and by adjusting the flow speed and pressure of the exhaust gas that are input in the turbocharger.
