Background technology
Along with the development of engine technology, the performance of engine constantly promotes.Promote performance automobiles enterprise in-cylinder direct-jet and turbocharging technologies of adopting on engine for reducing oil consumption more.Adopt above-mentioned technology to make the power per liter of engine promote the thermal load that also makes engine simultaneously and increase, cause the working temperature of engine piston to increase, piston temperature too high meeting causing gasoline engine produces pinking.At present, the temperature that reduces piston adopts piston cooling nozzle spraying machine oil cooling but to realize more.
The pressure size of the opening and closing of piston cooling nozzle, sealing, discharge characteristic, jet velocity etc. are determining the piston cooling effect.It is unreasonable that these aspects design, and the piston cooling does not reach desirable effect, causes the increase of oil consumption on the contrary.Automobile enterprise does not have the test unit of inspection and evaluation such as special piston cooling nozzle opening and closing pressure size, sealing, discharge characteristic, jet velocity more at present, the research and development expense that is unfavorable for shortening the piston cooling nozzle debugging cycle and reduces piston cooling nozzle.
The utility model content
The purpose of this utility model provides a kind of piston cooling nozzle test unit, solves the problem that existing piston cooling nozzle does not have the dedicated experiments apparatus for evaluating.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of piston cooling nozzle test unit comprises fuel tank, lubricating oil pump and cylinder body and oil pipe; Described fuel tank is connected lubricating oil pump in turn by oil pipe, first four-way, the ball valve and second four-way and machine oil receiving box, be provided with pressure-regulating valve in described first four-way, described second four-way places cylinder body main oil gallery porch, be provided with temperature sensor in second four-way, temperature sensor is connected with temperature indicating device, the described second four-way right-hand member interface is connected T-valve, T-valve right-hand member one tunnel is connected low pressure sensor, low pressure sensor is connected with the low pressure display device, high pressure sensor is connected on another road of T-valve right-hand member, and high pressure sensor is connected with the high pressure display device.
Preferably, the described first four-way lower end is connected by scavenge pipe free oil can.
Preferably, described cylinder body is the cylinder body of four cylinder band pistons.
Preferably, described T-valve is the wedge shape T-valve.
The beneficial effects of the utility model: can carry out test assessment to the opening and closing pressure size of piston cooling nozzle, sealing, discharge characteristic, jet velocity etc. by the piston cooling nozzle test unit, be optimized design according to test findings, shorten the research and development time and the expense of piston cooling nozzle greatly.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the utility model piston cooling nozzle test unit organigram.
Among the figure: 1. lubricating oil pump, 2. first four-way, 3. pressure-regulating valve, 4. scavenge pipe, 5. ball valve, 6. cylinder body, 7. second four-way, 8. temperature sensor, 9. temperature indicating device, 10. T-valve, 11. low pressure sensors, 12. low pressure display device, 13. high pressure sensors, 14. high pressure display device, 15. fuel tanks, 16. empty oil cans, 17. machine oil receiving boxes.
Embodiment
As shown in Figure 1, a kind of piston cooling nozzle test unit, the cylinder body 6 and the oil pipe that comprise fuel tank 15, lubricating oil pump 1 and four cylinder band pistons, fuel tank is connected lubricating oil pump 1, first four-way 2, ball valve 5 and second four-way 7 and machine oil receiving box 17 in turn by oil pipe, be provided with pressure-regulating valve 3, the first four-way lower ends in first four-way 2 and free oil can 16 arranged by scavenge pipe 4 connections.Second four-way 7 places cylinder body main oil gallery porch, is provided with temperature sensor 8 in second four-way, and temperature sensor is connected with temperature indicating device 9.The second four-way right-hand member interface is connected the T-valve 10 that wedge shape is arranged, T-valve right-hand member one tunnel is connected low pressure sensor 11, low pressure sensor is connected with low pressure display device 12, and high pressure sensor 13 is connected on another road of T-valve right-hand member, and high pressure sensor is connected with high pressure display device 14.
Principle of work of the present utility model: with lubricating oil pump and each sensor and each display device energized, connect signal line, second four-way upper end connects the piston cooling nozzle of testing.When checking piston cooling nozzle design opening and closing pressure, this T-valve places the low pressure sensor passage, and the low pressure display device will show the pressure condition of this moment.When carrying out the assessment of piston cooling nozzle oil beam quality, T-valve places the high pressure sensor passage, and the high pressure display device will show the pressure condition of this moment.When testing, can use truncated piston, the convenient like this injection target location of observing the oil bundle.Because this test is carried out at normal temperatures,, need use the substitute of machine oil commonly used instead in order to simulate the engine oil viscosity under the high temperature.
This piston cooling nozzle test unit can carry out test assessment to the opening and closing pressure size of piston cooling nozzle, sealing, discharge characteristic, jet velocity etc., be optimized design according to test findings, shorten the research and development time and the expense of piston cooling nozzle greatly.
