Abstract
The utility model relates to a V6 engine PCV oil-gas pipeline structure including an inlet manifold lower seat, the inlet manifold lower seat is provided with an upper end, the upper end is provided with an air inlet flange cooperated with an inlet manifold, the left side and the right side of the upper end are provided with air inlet flanges cooperated with a left cylinder cover and a right cylinder cover of a V6 engine, a left air inlet duct and a right air inlet duct are arranged in the inlet manifold lower seat, an oil-gas main pipeline is arranged in the middle of the lower part of the inlet manifold lower seat, a plurality of oil-gas branching pipelines communicated with the left air inlet duct or the right air inlet duct are successively arranged on the oil-gas main pipeline along the left side and the right side of the main pipeline, a PCV pipe port is arranged in the oil-gas main pipeline, and a PCV pipe adapter nozzle connected with the PCV pipe is arranged on the port. The V6 engine PCV oil-gas pipeline structure can improve the combustion balance of each cylinder and can prevent oil accommodating in a pressure stabilizing cavity of the inlet manifold.
Description
Technical field
The utility model belongs to the technical field of engine for automobile structure, and in particular, the utility model relates to a kind of V6 motor PCV Oil/Gas Pipe line structure.
Background technique
V6 motor refers to 6 cylinders, and cylinder is arranged as the motor of V-type, and each cylinder of this arrangement is coordinated mutually, so noise is very little, and smooth running; And V-type engine length and height dimension little, arrange very convenient, thereby brand-new the 4th generation VQ engine that has been considered to condense sophisticated technology in the field of business, becomes one of mark of car rank, is generally only applied on medium-to-high grade car.But in the V6 of prior art engine structure, PCV pipe is generally received in intake manifold pressure stabilizing cavity.Can not accomplish balanced distribution because the airflow influence in pressure stabilizing cavity makes the oil gas entering in pressure stabilizing cavity from PCV pipe, cause each cylinder burning there are differences.In addition, the part oil gas entering in pressure stabilizing cavity can be stained with on intake manifold wall, and long-term accumulation can cause trapped fuel in pressure stabilizing cavity.
Model utility content
The above-mentioned technical problem existing in order to solve prior art, the purpose of this utility model is to provide a kind of V6 motor PCV Oil/Gas Pipe line structure, and it can improve the harmony of each cylinder burning, and prevents intake manifold pressure stabilizing cavity inner product oil.
V6 motor PCV Oil/Gas Pipe line structure described in the utility model, comprise lower of intake manifold, it is characterized in that: lower of described intake manifold has upper end portion, described upper end portion is provided with the inlet flange coordinating with described intake manifold, and the left and right sides, described upper end portion is respectively arranged with the inlet flange coordinating with the left and right cylinder cap of V6 motor; In lower of described intake manifold, offer left intake duct and right intake duct, and under intake manifold, the lower middle position place of seat is provided with oil gas main pipeline, is disposed with the multiple oil gas subtubes that are communicated with left intake duct or right intake duct on described oil gas main pipeline along its pipeline left and right sides; And on described oil gas main pipeline, offer PCV tube opening, on described port, be provided with for managing with PCV the PCV pipe connecting-tube nozzle being connected.
V6 motor PCV Oil/Gas Pipe line structure described in the utility model compared with prior art has following beneficial effect:
PCV Oil/Gas Pipe line structure described in the utility model can make to enter more balanced being assigned in each cylinder of oil-gas ratio of oil gas main pipeline, thereby reaches the situation that each cylinder combustion case there are differences of improving; And because lower can not the causing of interface of oil gas subtube amassed oil.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the V6 motor PCV Oil/Gas Pipe line structure described in embodiment 1.
Fig. 2 is the internal structure schematic diagram of the V6 motor PCV Oil/Gas Pipe line structure described in embodiment 1.
Fig. 3 is oil gas main pipeline described in embodiment 1 and the structural representation of oil gas subtube.
Fig. 4 is the structural representation after the Oil/Gas Pipe line structure described in embodiment 1 coordinates with cylinder head cover.
Embodiment
Below with reference to embodiment and accompanying drawing, described V6 motor PCV Oil/Gas Pipe line structure is described in further detail.Embodiment 1
As shown in accompanying drawing 1-3, V6 motor PCV Oil/Gas Pipe line structure described in the present embodiment, comprise lower 10 of intake manifold, lower 10 of described intake manifold has upper end portion, described upper end portion is provided with the inlet flange 11 coordinating with described intake manifold, and the left and right sides, described upper end portion is respectively arranged with the left inlet flange 12 and the right inlet flange 13 that coordinate with the left and right cylinder cap of V6 motor; In lower of described intake manifold, offer left intake duct 14 and right intake duct 15, and under intake manifold, the lower middle position place of seat 10 is provided with oil gas main pipeline 30, is disposed with the multiple left oil gas subtube 31 and the right oil gas subtube 32 that are communicated with left intake duct or right intake duct on described oil gas main pipeline 30 along its pipeline left and right sides; And on described oil gas main pipeline, offer PCV tube opening 33, on described port, be provided with for managing with PCV the PCV pipe connecting-tube nozzle 20 being connected.As Fig. 4 shows the structure after intake manifold 50 and PCV pipe 60 is connected with lower 10 of intake manifold and cylinder head cover 40 respectively.In the structure of the present embodiment, enter more balanced being assigned in each cylinder of oil-gas ratio of oil gas main pipeline, thereby reach the situation that each cylinder combustion case there are differences of improving; And because lower can not the causing of interface of oil gas subtube amassed oil.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
