The utility model relates to a kind of internal combustion (IC) engine camshaft framework realizing two VCT and arrange, with air inlet OCV valve mounting hole and exhaust OCV valve mounting hole on this frame body, and respectively with air inlet OCV valve be vented air inlet that on OCV valve, oil-feed tank communicates and be vented oil-feed oil duct, the intake advance angle be communicated with the angle oil groove that lags with air inlet OCV valve advance angle oil groove, lag angle oil duct, and the exhaust advance angle be communicated with the angle oil groove that lags with exhaust OCV valve advance angle oil groove, lag angle oil duct; The opening of intake advance angle, the angle oil duct that lags corresponds to the advance angle oil groove of admission cam shaft and the angle oil groove positions that lags, and the opening of exhaust advance angle, the angle oil duct that lags corresponds to the advance angle oil groove of exhaust cam shaft and the angle oil groove positions that lags; Air inlet oil-feed oil duct and exhaust oil-feed oil duct block up by blocking up ball sealing.The utility model shortens advance angle oil duct, lag angle oil duct, reduces the boundary dimension of motor, and simplifies the oil circuit design of cylinder cap.
Description
Technical field
The utility model belongs to engine valve actuating mechanism technical field, relates to a kind of internal combustion (IC) engine camshaft framework realizing two VCT and arrange.
Background technique
At present, due to the demand of Fuel Economy, high power character and low emission, the two VCT system of intake and exhaust is widely adopted.
Arrange that the main task of the two VCT system of intake and exhaust is the two layout of OCV valve of intake and exhaust and the design of oil circuit thereof.In the layout of a lot of two OCV valves of motor both at home and abroad, or be that OCV valve is arranged on front cover, but OCV valve oil road length can be increased; Be OCV valve is arranged in camshaft bearing cover, but need on upper cover, increase OCV valve oil envelope; Be that OCV valve is arranged on upper cover, but need external OCV valve oil feeding line.And above-mentioned two OCV valve setting types all can increase motor length and width, high boundary dimension, and the design of the oil circuit of cylinder cap is made to become complicated.
Summary of the invention
The technical problems to be solved in the utility model is to provide one and reduces OCV valve oil road, the internal combustion (IC) engine camshaft framework that the two VCT of realization decreasing motor boundary dimension arranges.
In order to solve the problems of the technologies described above, with air inlet OCV valve mounting hole and exhaust OCV valve mounting hole on the internal combustion (IC) engine camshaft frame body that the two VCT of realization of the present utility model arranges, and respectively with air inlet OCV valve be vented air inlet oil-feed oil duct that oil-feed tank on OCV valve communicates and be vented oil-feed oil duct, the intake advance angle oil duct, the intake lag angle oil duct that are communicated with the angle oil groove that lags with air inlet OCV valve advance angle oil groove, the exhaust advance angle oil duct, the exhaust lag angle oil duct that are communicated with the angle oil groove that lags with exhaust OCV valve advance angle oil groove; The opening of intake advance angle oil duct, intake lag angle oil duct corresponds to the advance angle oil groove of admission cam shaft and the angle oil groove positions that lags, and the opening of exhaust advance angle oil duct, exhaust lag angle oil duct corresponds to the advance angle oil groove of exhaust cam shaft and the angle oil groove positions that lags; Air inlet oil-feed oil duct and exhaust oil-feed oil duct block up by blocking up ball sealing.
Working principle: machine oil enters into the oil duct bottom camshaft frame from the oil duct cylinder cap, OCV valve has 3 oil grooves, when OCV valve is installed on camshaft frame, 3 oil grooves of OCV valve are connected with the angle oil duct that lags with the upper oil duct of camshaft frame, advance angle oil duct respectively, and the advance angle oil duct of camshaft frame is connected with the angle oil groove that lags with the advance angle oil groove of camshaft with the angle oil duct that lags.After machine oil enters into OCV valve, can according to control needs, machine oil both can flow through advance angle oil circuit, also can flow through the angle oil circuit that lags, thus achieved the function at the control phase angle of VCT.
With air inlet OCV valve mounting hole and exhaust OCV valve mounting hole on camshaft frame of the present utility model, owing to being installed into the two OCV valve of exhaust, shortening advance angle oil duct, lag angle oil duct, reduces the boundary dimension of motor, and simplify the oil circuit design of cylinder cap.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1, Fig. 2 are internal combustion (IC) engine camshaft framework generalized sections of the present utility model.
Embodiment
As shown in Figure 1, 2, on internal combustion (IC) engine camshaft frame body 1 of the present utility model with air inlet OCV valve 3 mounting hole and exhaust OCV valve 4 mounting hole.Frame body 1 is processed with respectively with air inlet OCV valve 3 be vented air inlet oil-feed oil duct P1 that oil-feed tank on OCV valve 4 communicates and be vented oil-feed oil duct P2.Frame body 1 is also processed with the intake advance angle oil duct A1, the intake lag angle oil duct B1 that are communicated with the angle oil groove that lags with air inlet OCV valve 3 advance angle oil groove respectively, the exhaust advance angle oil duct A2, the exhaust lag angle oil duct B2 that are communicated with the angle oil groove that lags with exhaust OCV valve 4 advance angle oil groove respectively.The opening of intake advance angle oil duct A1, intake lag angle oil duct B1 corresponds respectively to the advance angle oil groove of admission cam shaft and the angle oil groove positions that lags, air inlet OCV valve 3 advance angle oil groove is communicated with by intake advance angle oil duct A1 with the advance angle oil groove of admission cam shaft, and the air inlet OCV valve 3 angle oil groove that lags is communicated with by intake lag angle oil duct B1 with the angle oil groove that lags of admission cam shaft.The opening of exhaust advance angle oil duct A2, exhaust lag angle oil duct B2 corresponds to the advance angle oil groove of exhaust cam shaft and the angle oil groove positions that lags, exhaust OCV valve 4 advance angle oil groove is communicated with by exhaust advance angle oil duct A2 with the advance angle oil groove of exhaust cam shaft, is vented the OCV valve 4 angle oil groove that lags and is communicated with by exhaust lag angle oil duct B2 with the angle oil groove that lags of exhaust cam shaft.Air inlet oil-feed oil duct and exhaust oil-feed oil duct are by blocking up ball 2 shutoff.
