Engine Cylinder Liner for Toyota 2KD Europe Truck

Common failure and prevention of two kinds of cylinder liner 1. Typical problems of dry cylinder liner Cylinder liner and cylinder body fit poorly: insufficient interference during installation, resulting in reduced heat dissipation efficiency, local overheating caused cylinder pulling. Uneven inner wall wear: piston offset cylinder (connecting rod bending or cylinder block deformation) leads to unilateral wear of cylinder liner, appearing "waist drum shape". Preventive measures: Periodically check the cylinder pressure to avoid long-term overload operation of the engine, and measure the matching gap between the cylinder liner and the cylinder block during overhaul (standard value is usually 0.02-0.05mm).   2. Typical problems of wet cylinder liner Aging of the seal ring leakage: vehicles used for more than 5 years are prone to hardening of the seal ring, resulting in coolant infiltration into the oil pan (oil emulsification, milky white). Cavitation (cavitation) damage: Bubbles in th…
