Abstract
The utility model discloses a kind of combustion system of engine constant current testing device, comprise core box, described core box is provided with core box pedestal, air intake duct, exhaust duct and firing chamber, core box is integrated casting structure, described core box pedestal is provided with register pin or the hole of the steady flow testbed frame location fit with engine, and described core box pedestal is provided with the corresponding fastening bolt holes connected of frame steady flow testbed with engine; Firing chamber is arranged on the lower surface of core box pedestal, and air intake duct and exhaust duct are thin-wall construction and V-shaped angle between air intake duct and exhaust duct outer wall.The beneficial effects of the utility model are: rational in infrastructure, in integrated process depanning easily and material-saving, and because Structure composing is closer to the as-cast condition of real engine, can embody the current stabilization experimental performance of engine more accurately, and this infrastructure cost processing charges and Master Cost significantly reduce and intensity raising.
Description
Technical field
The utility model relates to field of internal combustion engine, particularly relates to a kind of combustion system of engine constant current testing device.
Background technology
Combustion system is the core system of engine, in combustion system performance history, have a series of test to the requirement checking it whether to meet engine, constant current testing device is just used to detect inlet and outlet performance and a kind of device coordinating air motion situation with firing chamber thereof.
Traditional approach adopts trial-production overall cylinder cover to check, and cost is high, and the cycle is long.Current most engine production producer adopts trial-production core box to replace cylinder cap, mainly contains following several mode:
1, make simple and easy combustion system by gypsum, resin etc., comprise inlet and outlet road and firing chamber
2, add formula mode by machine, core box is divided into upper and lower two parts, then to be linked together the complete core box of composition one by bolt etc.
Gypsum coremaking box is frangible, resin core box cost is higher, be convenient to repair air flue by machining mode, but because it is directly obtained by machining mode, wall is smooth, its current stabilization experimental performance is than combustion system current stabilization experimental performance height about the 5%-10% of real engine, can not better reflect actual casting state performance, and by the core box that machining mode is processed, weight of selecting materials is large, processing capacity large, economy and cost of labor is caused to improve.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of combustion system of engine constant current testing device.
To achieve these goals, the technical solution of the utility model is: a kind of combustion system of engine constant current testing device, comprise core box, described core box is provided with core box pedestal, air intake duct, exhaust duct and firing chamber, described core box is integrated casting structure, described core box pedestal is provided with register pin or the hole of the steady flow testbed frame location fit with engine, and described core box pedestal is provided with the corresponding fastening bolt holes connected of frame steady flow testbed with engine; Described firing chamber is arranged on the lower surface of core box pedestal, and described air intake duct and exhaust duct are thin-wall construction and V-shaped angle between air intake duct and exhaust duct outer wall.
Further, as a kind of preferred version, the outer wall at described air intake duct correspondence " V " clevis angle is provided with inlet valve guide hole.
Further, as a kind of preferred version, the outer wall at described exhaust duct correspondence " V " clevis angle is provided with exhaust valve guide hole.
The beneficial effects of the utility model are: rational in infrastructure, in integrated process depanning easily and material-saving, and because Structure composing is closer to the as-cast condition of real engine, can embody the current stabilization experimental performance of engine more accurately, and this infrastructure cost processing charges and Master Cost significantly reduce and intensity raising.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is vertical view of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.
As shown in Fig. 1 Fig. 2, a kind of combustion system of engine constant current testing device, comprise core box, described core box is provided with core box pedestal 1, air intake duct 2, exhaust duct 3 and firing chamber 4, described core box is integrated casting structure, described core box pedestal 1 is provided with register pin or the hole 5 of the steady flow testbed frame location fit with engine, and described core box pedestal 1 is provided with the corresponding fastening bolt holes 6 connected of frame steady flow testbed with engine; Described firing chamber 4 is arranged on the lower surface of core box pedestal 1, and air intake duct 2 and exhaust duct 3 are thin-wall construction and V-shaped angle between air intake duct 2 and exhaust duct 3 outer wall.The outer wall at air intake duct 2 correspondence " V " clevis angle is provided with inlet valve guide hole 7.The outer wall at exhaust duct 3 correspondence " V " clevis angle is provided with exhaust valve guide hole 8.This novel test unit directly correspondence position processing gas inlet seat ring 9 and exhaust valve seat insert 10 in firing chamber 4, decreases later stage assemble flow, saves time and manually, improves efficiency.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection domain of the present utility model.
