Fuel economy and emission standards:
The GW4G15F engine is equipped with a multi-point electronic control fuel injection system, which achieve
precise injection in each intake manifold, enhancing the engine's power output and responsiveness. Additionally,
the engine introduces a variable valve timing system that intelligently adjusts the opening and closing times
based on different engine conditions, achieving optimal combustion efficiency and higher fuel economy. To meet
the stricter National VI emission standards, the GW4G5F has undergone several improvements, including increasing
the fuel injection pressure and optimizing the tumble ratio of the intake ports. These measures not only improve
the turbocharger's speed but also significantly enhance the vehicle's driving comfort and NVH performance.
