Description and operation
Continuous Variable Valve Timing (CVVT) system advances or retards the valve
timing of the exhaust valve in accordance with the ECM control signal which is calculated
by the engine speed and load.
By controlling CVVT, the valve over-lap or under-lap occurs, which in turn improves
fuel efficiency, reduces exhaust gases (NOx, HC) and improves engine performance
by reducing pumping loss, generating internal EGR effect, improving combustion stability,
improving volumetric efficiency and increasing expansion work.
This system consists of
-the CVVT Oil Control Valve (OCV) which supplies the engine oil to the cam phaser
or cuts the engine oil from the cam phaser in accordance with the ECM PWM (Pulse
With Modulation) control signal,
-and the Cam Phaser which varies the cam phase by using the hydraulic force of
the engine oil.
The engine oil released from the CVVT oil control valve varies the cam phase
in the direction (Intake Advance/Exhaust Retard) or opposite direction (Intake Retard/Exhaust
Advance) of the engine rotation by rotating the rotor connected with the camshaft
inside the cam phaser.

Kia Stinger (CK) 2018-2023 Service Manual: Restraint
General information
General
The supplemental restraint system (SRS) is designed to supplement the seat belt
to help reduce the risk or severity of injury to the driver and passenger by activating
and deploying the driver, passenger, side airbag and seat belt pretensioner in certain
frontal or side collisions.
The SRS (Airbag) consists of: a driver side airbag module with the folded cushion
and an inflator unit located at the center of the steering wheel, a passenger side
airbag module with the folded cushion assembled with inflator unit located in the
passenger side crash pad, side airbag modules with the folded cushion and an inflator
unit located in the front seat, and curtain airbag modules with folded cushions
and inflator units located inside the headliner.
