The cylinder liner is used in the diesel engine of the XGC55 crawler crane (such as the Cummins QSB6.7 or SC7H series), as a pressure-bearing part of the combustion chamber, through the high-precision cylindrical surface and piston ring, to seal the gas and conduct heat. Refer to the design of XCMG similar models, using high-strength cast iron material (such as HT250), suitable for 180-220 horsepower engine, can withstand the burst pressure of more than 150bar.
