Abstract
The utility model discloses an air inlet structure of an engine cylinder cover, which comprises a cylinder cover and an intake manifold and is characterized in that a transitional connecting plate is further arranged between the cylinder cover and the intake manifold and internally provided with an air passage communicating the cylinder cover with the intake manifold in a matched way. The air inlet structure can realize malposition adjustment of the air passage between the cylinder cover and the intake manifold, thus leading to smooth air inflow and improving air inflow efficiency; and simultaneously, the air inlet structure is added with the installation space of a sensor, thus being directly applied in advanced EFI (electronic fuel injection) engines without conducting mold reopening on the whole air inlet structure, and saving manufacture cost.
Description
Technical field
The utility model relates to the architecture advances at a kind of engine cylinder cap intake manifold place.
Background technique
In the prior art, the motor of a kind of model 368Q, this motor are carburetor engine, and its cylinder head air inlet place structure is, employing directly is connected intake manifold on the cylinder head, adopts the sealing gasket sealing between intake manifold and the cylinder head and adopts bolt or double-screw bolt to tighten up.The intake manifold the other end is connected on the Carburetor.This engine intake manifold and cylinder head are two independent members of making, be to adopt double-screw bolt to connect during assembling, so can not be fully corresponding between the air flue on the air flue that intake manifold many times after assembling, can occur and the cylinder head, cause air inlet not smooth, intake efficiency is not high.Simultaneously, adopt the better EFI formula of performance motor to substitute carburetor engine in the art and become trend, and this existing air intake structure is the design on the former carburetor engine, limited space between its gas manifold and Carburetor and the crankcase body, be difficult to arrange the sensor that detects air flue parameters such as airway pressure, so be not suitable for being used for EFI formula motor.
The model utility content
At the prior art above shortcomings, technical problem to be solved in the utility model provides the high engine cylinder cap air intake structure of a kind of intake efficiency, makes it be suitable for EFI formula motor simultaneously.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:
A kind of engine cylinder cover air intake structure, comprise cylinder head and intake manifold, its characteristics are also to be provided with between described cylinder head and the intake manifold transition connecting plate, are provided with to the inner coupling of this transition connecting plate the air flue that is communicated between cylinder head suction port and the intake manifold.Further, for guaranteeing sealing, between transition connecting plate and cylinder head and intake manifold, be provided with sealing gasket.
Adopted transition connecting plate in the utility model, transition connecting plate left end gas port is as the form of mating fully with the intake manifold air flue, transition connecting plate right-hand member gas port is as the form of mating fully with the cylinder head suction port, so just dislocation is originally adjusted, make its air inlet smooth and easy, improved intake efficiency.Simultaneously, air intake structure after the improvement is suitable for using in EFI formula motor very much, because this air intake structure has increased space length between cylinder head and the intake manifold by transition connecting plate, so just can on newly-increased transition connecting plate sensor be set easily detects parameters such as suction pressures, sensor reaches signal the ECU ECU (Electrical Control Unit) again and calculates, analyzes, contrasts, various operating mode needs control fuel injection quantitys according to motor guarantee that motor has good power character, Economy and emission performance.Like this, only need at the EFI formula motor of setting up on the former air intake structure basis after a transition connecting plate can make it be applicable to improvement, so need not to have saved manufacture cost with regard to whole air intake structure die sinking again.Simultaneously, transition connecting plate can be produced separately, and the processing technology simple possible has simple in structurely, processes cheap advantage.
Description of drawings
Fig. 1 is the utility model assembly structure schematic representation.
Fig. 2 is a transition connecting plate side view in the utility model.
Among the figure, 1 is Carburetor, and 2 is intake manifold, and 3 is sealing gasket, and 4 is double-screw bolt, and 5 is cylinder head, and 6 is crankcase body, and 7 is transition connecting plate.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, engine cylinder cap air intake structure of the present utility model, comprise cylinder head 5 and intake manifold 2, cylinder head 5 lower ends are crankcase body 6, intake manifold 2 the other ends connect Carburetor 1, also be provided with transition connecting plate 7 between described cylinder head 5 and the intake manifold 2, be provided with to these transition connecting plate 7 inner couplings the air flue that is communicated between cylinder head 5 suction ports and the intake manifold 2.The quantity that described coupling is meant air flue is all consistent with two ends with size, and transition connecting plate 7 left end gas ports and intake manifold 2 air flues mate fully, transition connecting plate 7 right-hand member gas ports and cylinder head 5 suction ports mate fully.Be respectively arranged with sealing gasket 3 between transition connecting plate 7 two ends and intake manifold 2 end faces and cylinder head 5 end faces to guarantee tightness, adopt double-screw bolt 4 to make during assembling and tighten up sealing between the three.Transition connecting plate 7 concrete profiles can be according to the intake manifold 2 of different profiles and cylinder head 5 and different, and also can selecting for use in various degree again according to actual conditions during connection, the connection of series connects fastening with clamping bolt or double-screw bolt.
The utility model can be adjusted the air flue dislocation between cylinder head and the intake manifold, makes its air inlet smooth and easy, improves intake efficiency; The utility model has increased the sensor installing space simultaneously, and it can be directly applied in the more advanced EFI formula motor, need not air intake structure integral body die sinking has again been saved manufacturing expense.
Claims (2)
1. engine cylinder cover air intake structure, comprise cylinder head and intake manifold, it is characterized in that also being provided with between described cylinder head and the intake manifold transition connecting plate, be provided with to the inner coupling of this transition connecting plate the air flue that is communicated between cylinder head suction port and the intake manifold.
2. engine cylinder cover air intake structure as claimed in claim 1 is characterized in that being provided with sealing gasket between described transition connecting plate and cylinder head and the intake manifold.
