オイルジエツト。 The jet nozzle part of the oil jet main body for piston cooling is formed by a shape memory alloy that remembers the shape during normal use by extending the tip of the jet nozzle part to a position near the big end of the piston connecting rod. A piston cooling device characterized in that the jet nozzle portion of the oil jet body can be deformed to a position that prevents the piston from interfering with the large end of the connecting rod during the piston installation work in which the piston is installed in the cylinder block. oil jet.
