(2) simple in structure, cost is low, make easily, produce easy to install, be mainly used in the mating power of light duty cross-country car, light bus, light truck and light-duty notchback, can satisfy the needs of the low pollution of Europe III emission standard, low fuel oil consumption petrol engine etc., practical.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the plan structure schematic representation of Fig. 1.
Among the figure: 1-valve body, 1a-oil inlet hole, 1b-oil outlet, 1c-annular table, 2-steel ball, 3-spring, 4-obstruction, 5-jet pipe, 6-mounting plate.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of cooling jet of engine piston, by the hollow valve body 1 that annular table 1c is arranged in oil inlet hole 1a and the oil inlet hole 1a and oil outlet 1b is arranged is arranged, place the spring 3 in the valve body 1, place steel ball 2 between valve body 1 inner spring 3 and the annular table 1c (under the pressure of spring 3, steel ball 2 stops up and sealing oil inlet hole 1a), one end and valve body 1 fixed seal connection, another section are positioned at valve body 1 and the jet pipe 5 that fixedly is communicated with obstruction 4, one ends of spring 3 pivot bush units and the oil outlet 1b of valve body 1 and the mounting plate 6 that is fixedly connected on the valve body 1 constitute.
It is 2 millimeters that this embodiment designs oil inlet hole 1a diameter, and oil spout cracking pressure (being the pressure that steel ball 2 is removed sealing oil inlet hole 1a) for 0.2MPa, as required, also can design different parameters, regulates nozzle oil spout initial pressure, to guarantee favorable cooling effect.
During use, the present embodiment nozzle is installed in the crankcase of engine cylinder body by mounting plate 6, the oil inlet hole 1a of valve body 1 is connected with the main oil gallery of engine lubrication system, jet pipe 5 is connected with the lubricating cooling oil road of engine piston.During work, along with the rising of engine speed, its engine oil pressure also constantly raises, after the critical pressure value above design, spring is compressed, and oil enters valve body 1 in and washes steel ball 2 open, enters piston head, recirculation from oil outlet 1b through jet pipe 5 injections again through main oil gallery, oil inlet hole 1a; By this embodiment's piston cooling nozzle directly lube pistons inwall, cooling piston top.
The petrol engine that adopts the utility model to provide, emission performance reaches the EUR0III rules, satisfy GB18352.3-2005 " light-duty vehicle pollutant emission limit and method of testing (the III) " mandatory standard that country is about to enforcement, satisfy the local emission standard in DB11/105-1998 and DB11/044-1999 Beijing simultaneously.
The utility model is not limited to the foregoing description, and the utility model content is described all can implement and have described good result.
