PISTON COOLING STRUCTURE IN COMBUSTION ENGINE

摘要

A piston cooling structure for an engine includes a first nozzle and a second nozzle for injecting a cooling liquid towards a back face of a piston that reciprocally move within a cylinder bore along a cylinder axis line. The first angle of inclination of an axis of the first nozzle relative to the cylinder axis line is set to be smaller than the second angle of inclination of an axis of the second nozzle relative to the cylinder axis line.

1. A piston cooling structure for a combustion engine which comprises:
first and second nozzles configured to inject a cooling liquid towards a back face of a piston which reciprocatingly move along a cylinder axis line within a cylinder bore, the first and second nozzles having axes that are inclined at first and second angles relative to the cylinder axis line, respectively, in which the first angle of inclination relative to the cylinder axis line is set to a value smaller than the second angle of inclination relative to the cylinder axis line.
