Continuous Variable Valve Actuator (CVVA) "Reference Model: Patent Pending"
:Great reduction of pumping loss by controlling the air-intake with valve lift volume which replaces the movement of throttle valve.
:Continuous variability of valve lift became reality by rocking movement of control lever over rocker arm.
Core technology products for CVVA
-Assembly of Sintered Cam Shaft
-Assembled Cam Shaft
-Sintered Valve Sheet
-Rocker Arm
