Abstract: A refrigerator is provided. The refrigerator may include first and second refrigerant paths that separately distribute refrigerant, a first cooling chamber connected with a first cold air duct, a second cooling chamber connected with a second cold air duct, and a third cooling chamber connected with a third cold air duct. Cold air generated by a first evaporator is provided to the first cold air duct to cool the first cooling chamber, cold air generated by a second evaporator, which receives refrigerant from the first evaporator, is provided to the second cold air duct to provide concentrated cooling to the second cooling chamber, and cold air generated by a third evaporator is provided to the third cold air duct to cool the third cooling chamber.

Abstract: A cylinder liner that can be accurately positioned and can securely maintain a stable state relative to a base metal of a cylinder block to thereby minimize deformation of the cylinder bore, limit abrasion of a piston and a piston ring, reduce consumption of oil and to effectively prevent damage to an engine.
