Abstract

The invention belongs to the technical field of engines, and particularly relates to a cooling nozzle and a method for improving the targeting efficiency. The cooling nozzle comprises a spray head anda nozzle, wherein a first channel is arranged in the spray head, a connecting piece is arranged on the spray head, and a second channel communication with the first channel is arranged in the connecting piece; one end of the nozzle is mounted on the connecting piece, the nozzle is in communication with the second channel, and a streaming piece is arranged in the other end of the nozzle. The engine oil in the cooling nozzle flows from the first channel to the second channel and then the engine oil is subjected to flow rate adjusting passing through the streaming piece, and the flow rate of theengine oil in the piston cooling nozzle is subjected to flow rate adjusting by arranging the streaming piece, so that the flow rate in the section of a pipe of the cooling nozzle is more uniform, sothat the targeting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a cooling nozzle and a method for improving shooting efficiency. Background technique [0002] When the structure of the piston is fixed and the inlet pressure of the piston is constant, the flow rate Q of the piston is 1 It is determined that when the oil is sprayed from the nozzle, due to the interaction between gas and liquid and the limitation of the piston structure, only part of the oil quantity Q 2 into the cooling oil chamber of the piston. The target efficiency η of piston improving target efficiency is defined as: the engine oil ejection quantity Q of piston improves target efficiency 1 / The quantity of engine oil flowing out of the internal cooling oil chamber of the piston Q 2 . [0003] In the prior art, the method for improving the shooting efficiency of the diesel engine piston requires a bending structure. When the fluid passes through the bending...
