 Product Details

YC6J SERIES DIESEL

Features & Benefits

● Designed and developed based on FEV technology platform and incorporate Europe's most compact, lightweight design.
● Pistons are formed with interior oil passages-Reduce greatly surface operating temperature while maximize piston ring life.
● 4-valve per cylinder configuration-Improve significantly mass flow rate through intake and exhaust valves, producing a more intense combustion..
● Wet sleeve liners- Reduce frictional wear dramatically while allow for ease of maintenance..
● Cylinder liners are formed with cross-hatching grooves on the surface-Reduce overall oil consumption.
● Cylinder block skirt is reinforced with ribs to provide structural stiffness- Minimize deformation while extend performance life.
● HONEYWELL turbocharger equipped with by-pass valve -Deliver quick response and higher performance.
