Problems solved by technology

The piston cooling nozzle is connected to the oil passage in the valve body through the oil inlet end of the oil injection pipe radially penetrating through the installation hole of the oil injection pipe arranged on the collar, that is to say, the oil injection pipe is arranged radially along the circumference of the valve body. In addition, installation parts need to be installed on the valve body, resulting in complex overall structure of the piston cooling nozzle, high manufacturing cost, large volume, and heavy weight, which not only occupies a large installation space, but also interferes with the crankshaft and connecting rod in the engine. Poor safety hazard, and poor compactness and poor stability after installation

Abstract

The invention discloses a cylinder body press-fitted with a piston cooling nozzle. The piston cooling nozzle is press-fitted in a corresponding cylinder hole of the cylinder body in a way of spraying towards an exhaust side position at the bottom of a piston; the piston cooling nozzle is press-fitted in a crankshaft hole of the cylinder body, so that the assembly time of the piston cooling nozzle is saved, and the movement radius of a crank-link mechanism is increased; and the spraying position is more effectively guaranteed as comparison with that of the existing structure.

Description

technical field [0001] The invention relates to a cylinder, in particular to a cylinder block with a piston cooling nozzle press-fitted. Background technique [0002] In order to prevent the gasoline engine from knocking due to the high temperature of the combustion chamber and piston when the engine is working, the designer designed a piston cooling nozzle to reduce the temperature of the piston. The piston cooling nozzle is mainly controlled by the oil pressure, that is, the steel ball is sealed at the oil inlet port through the built-in spring preload. When the oil pressure is greater than the spring preload, the steel ball compresses the spring, and the lubricating oil sprays the piston through the cooling nozzle. , Since the temperature of the lubricating oil is lower than that of the piston, it has the effect of cooling the piston. The piston cooling nozzle is connected to the oil passage in the valve body through the oil inlet end of the oil injection pipe radially p...
