The YC6MK series engine is used in trucks. It is developed based on the AVL technology platform, which has the following features and benefits. Firstly, one-piece cylinder head and wet sleeve liners can extend the service life. Secondly, high-efficiency turbochargers can enhance responsiveness and performance life, providing prompt boost across the operating range. Thirdly, it has an intelligent electronic control system with complete functions. Besides, camshafts and good roller rocker arm devices can reduce friction while improving fuel economy. , the compression release engine brake improves safety, especially while driving down slope. Simultaneously, point-line meshing gear drive can bring you the best ride comfort, while reducing noise and vibration. Finally, the compression release engine brake improves safety, especially while driving down slope.
