Accompanying drawing explanation
Fig. 1 shows the outside drawing of air flue of the present invention simulation cylinder sleeve;
Fig. 2 shows the scheme of installation of air flue of the present invention simulation cylinder sleeve.
Embodiment
Describe technical scheme of the present invention in detail by the following examples, following embodiment is all exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not be interpreted as being the restriction to technical solution of the present invention.
As shown in Figure 1, engine air flue simulation cylinder sleeve of the present invention, includes simulation liner body 1, upper flanges 2, lower end flanges 3, small sealing ring 4, large sealing packing ring 5, location and installation through hole 7 and quick connector 6.
The internal diameter of simulation liner body 1 changes, as required for the air intake duct equal diameters with engine cylinder cover to be measured, for adapting to the detection to different model engine.
The inwall of simulation liner body 1 is smooth surface, for simulating real engine cylinder sleeve; The simulation internal diameter D of liner body and the air intake duct equal diameters of diesel engine cylinder cover to be measured, the height H of simulation cylinder sleeve is H=1.75D.
Upper flanges 2 and lower end flanges 3 are individually fixed in the close end at described simulation liner body 1 outer wall two ends; There is a little distance the nearest end of upper flanges 2 range simulation liner body, and equally, also there is a little distance flange range simulation liner body nearest end in lower end.
Upper flanges 2 is evenly equipped with six location and installation through holes 7, is coordinated by bolt for same testing table.
The center of circle of the inscribed circle of location and installation through hole and the center of circle of described lower end flanges are all positioned on the center line of described simulation cylinder sleeve; And the radius of described inscribed circle is greater than the radius of described lower end flanges.When this spline structure can ensure simulation cylinder sleeve to assemble with test table top, bolt and lower end flange through location and installation through hole are interfered, and can spacing by lower end flanges, ensure in testing process, simulate cylinder sleeve and test combining closely of table top.
When carrying out the installation of simulating cylinder sleeve, as shown in Figure 2, first make the lower surface of upper flanges concordant with the mounting groove 9 of test table top 10, by rotary simulation liner body 1, make six location and installation through holes and test the threaded hole of table top to it, using bolt to be arranged on urgent for simulation cylinder sleeve on testing table.
Upper flanges is for simulating the installation of cylinder sleeve at test table top, and the location of diesel engine cylinder cover on simulation cylinder sleeve, and simulation outer wall of cylinder jachet is equipped with quick connector, for Bonding pressure sensor, to measure the gaseous tension by simulating cylinder sleeve.The upper and lower both ends of the surface of simulation cylinder sleeve are respectively equipped with an O-ring seal, for the sealing of diesel engine cylinder cover with simulation cylinder sleeve, and the sealing of simulation cylinder sleeve and eddy current dynamometer.
The top end face of the nearly upper flanges of simulation liner body is provided with O connected in star; Small sealing ring is arranged in described O connected in star.Wherein, the thickness of small sealing ring is greater than the degree of depth of O connected in star, can utilize the elasticity of small sealing ring like this, improves tested cylinder cap and the sealing of simulating cylinder sleeve upper end.
Tested cylinder cap is by special location-plate 8, the top of simulation liner body 1 can be lain in, rubber seal in the O type groove of simulation cylinder sleeve upper surface, under the effect of self gravitation, compresses, thus ensures cylinder cap and the positiver sealing of simulating cylinder sleeve by tested cylinder cap.
Outer wall between the proximal end of lower end flanges and described simulation liner body is provided with large sealing packing ring.Can be fitted tightly with the upper surface of swirl momentum meter 11 by the lower end flange face simulating cylinder sleeve, swirl momentum meter is in the process regulated from bottom to top, below the lower end flanges of simulation cylinder sleeve, part can sink in the groove of momentum meter, simultaneously by the large sealing packing ring on simulation outer wall of cylinder jachet, realize the positiver sealing between simulation cylinder sleeve and momentum meter.
Quick connector is arranged on the described simulation liner body outer wall between described upper flanges and described lower end flanges.
