An engine cylinder liner construction, comprising:
- a cylinder block;
- a cylinder liner cast into the cylinder block, the cylinder liner having a tubular portion and a number of spines integrally formed on an outer surface of the tubular portion, the cylinder liner being so cast, such that an annular extended portion extending from the cylinder block is sandwiched between an upper end portion of the cylinder liner and the cylinder head;
- and
- a chamfered portion formed at an end portion of the tubular portion which faces a cylinder head by chamfering the end portion together with the spines located thereat, the chamfered portion having an extended width in a radial direction of the cylinder liner larger than a protrusion width of the spines in the radial direction of the cylinder liner and smaller than a thickness of the cylinder liner.
