YC6L SERIES DIESEL

Features & Benefits

● Designed and developed based on FEV technology platform.
● 4-valve per cylinder configuration-Improve significantly mass flow rate through intake and exhaust valves, producing a more intense combustion.
● Highly efficient turbocharger- Enhance response, providing prompt boost across the operating range.
● Compact, lightweight design-Provide the solution to reduce overall vehicle weight and increase payload capacity.
● Wet sleeve liners- Reduce frictional wear dramatically while allow for ease of maintenance.
● Give you the best comfort ride with less noise and vibration.
