Press-fit wet liners with O-ring sealing ensure thermal stability and repairability. Reinforced cast-iron block resists distortion. Optimized water jacket provides uniform cooling for heavy-duty endurance.
Coolant flows around wet liners to absorb and carry away combustion heat. Pistons move inside the liners to convert fuel energy into mechanical power for driving the truck.
Eliminates bore scoring, coolant leakage, and compression loss caused by worn cylinder liners. Restores engine sealing and thermal stability for consistent heavy-duty performance.
