  • EGR

    The EGR Valve is an essential emission control device that contributes to environmental protection and improvements in fuel efficiency and performance.
    By recirculating a portion of the exhaust gas into the cylinders, it lowers combustion chamber temperatures, reduces nitrogen oxides (NOx), and increases engine efficiency.
    This enables eco-friendly operation by meeting emission regulations.

  • Actuator

    The Turbocharger Actuator (ETA) is a core component responsible for the precise control of turbocharger performance.
    It enhances the vehicle's fuel efficiency and power output by accurately regulating the wastegate valve.
