The intake manifold adopts the throttle valve body to reduce the overall height of the engine at the lateral face of a pressurizer tank and causes the air intake consistency to be better by the fluid analysis by a computer; and the entire manifold has very compact structure, thereby meeting the arrangement requirement that the space of a front chamber is narrow.
Description
Technical field
The present invention relates to a kind of intake manifold of automobile put-put.
Background technique
Motor makes the compact layout that is beneficial to the preceding storehouse of automobile of structure as far as possible under the prerequisite that satisfies aspects such as performance, particularly evident on automobile with small output volumn especially.
General motor needs thin and long intake manifold when middle low-speed running in whole operation interval, to obtain the high moment of torsion output of low speed, then need short and thick intake manifold to obtain big power in high speed.In order to satisfy the function needs of motor in whole operating range, generally adopt variable air inlet road technology.But adopt this technology to make intake manifold structure more complicated, design cost rises, the motor of big discharge capacity in generally being suitable for, for small displacement engine if use this structure: the compactness that, can not guarantee structure; Two, design cost rises, so should not adopt.
Summary of the invention
Purpose of the present invention just provides a kind of intake manifold of being convenient to install and use on the small displacement engine, and the little and reasonable structural arrangement of volume is to satisfy the narrow and small arrangement requirement in Qian Cang space.
For achieving the above object, the technical solution used in the present invention is: a kind of intake manifold, it is characterized in that: intake manifold comprises manifold body, being furnished with the cylinder cap flanged surface on the manifold body is connected with cylinder cap, the side of cylinder cap flanged surface is provided with throttle valve end face is installed, and the position is fixed with the upper and lower semi-body pipe lid of scroll casing shape about the manifold body.
The present invention has adopted the project organization of snail type intake manifold, pay attention to obtaining low speed and large torque output, adopt throttle valve body to reduce the height of motor complete machine in the pressure stabilizer side and made that by the computer fluid analysis air inlet conformity is better, whole manifold structure is quite compact, can satisfy the narrow and small arrangement requirement in Qian Cang space.

Each isolation of components state perspective view among Fig. 4 the present invention.
Embodiment
Referring to accompanying drawing, intake manifold comprises manifold body 10, be furnished with cylinder cap flanged surface 14 on the manifold body 10 and be connected with cylinder cap, the side of cylinder cap flanged surface 14 is provided with throttle valve end face 15 is installed, and the manifold body upper and lower semi-body pipe that the position is fixed with scroll casing shape 10 about covers 20,30.The separation processing method of many each parts of employing can be processed into the volute shape of comparatively desirable and relative complex easily, again parts can be finished moulding by the mode of welding.The employing snail type intake duct of institute's moulding is that air-flow is by the cyclone mode feeding, as shown in Figure 1, 2, throttle valve body is installed in the side of cylinder cap flanged surface 14, be installed in the side of pressure stabilizer 18 in other words, its air-flow flows into and enters cylinder head by the airflow arrows direction after throttle valve body is installed end face 15, can guarantee that by computer fluid analysis and verification experimental verification the uniformity of effective air inflow and each cylinder air inlet is better.
The current path of intake manifold is actually and is constituted by each parts among the present invention, specifically be exactly that described upper and lower semi-body pipe lid 20,30 respectively is provided with first, second and third intake duct portion 21,22,23 and 31,32,33, they and first, second and third intake duct portion 11,12,13 on the manifold body 10 first, second and third intake duct integral body of formation that cooperatively interacts.Described upper and lower semi-body pipe lid 20,30 is exactly the shell of halfbody shape, when they with formed current path after manifold body 10 is connected.
Between described manifold body 10 bottoms and the lower semi-body pipe lid 30 transition base 40 is arranged, it is provided with manifold body 10 bottoms and lower semi-body pipe and covers the connecting part that 30 tops cooperate, and described manifold body 10 upper and lower semi-body pipes lid 20,30 and base 40 constitute the intake manifold integral body of scroll casing shape.As shown in Figure 4, it is very easily that whole intake manifold is decomposed into that four parts process, and has so just simplified the making and the moulding process of mould.
For being connected and installation of reasonable Arrangement on intake manifold and other parts, the present invention has also made rational layout to the mounting point of sensor, brake boost vacuum pump flexible pipe and wire harness, specifically just between described first and second intake duct portion 21,22, air inlet pressure sensor mounting flange face 24, brake boost vacuum pump hose coupling 25 are set, in between first and second intake duct portion 21, the 22 and edge between second and third intake duct portion 22,23 wire harness bracket 26 is set, fuel oil piece-rate system interface 16 next doors at crankcase ventilation system interface 17.The installation of adaptor parts is brought convenience, also guaranteed the simplification and the compactness of intake manifold self structure simultaneously.
In concrete application of the present invention, the selection of material also is significant, and in conjunction with structural feature of the present invention, described manifold body 10 upper and lower semi-body pipes lid 20,30 and base 40 adopt the engineering plastics molding and forming and be welded as a whole.In conjunction with Fig. 4, four parts are formed from top to down, and the burst place adopts and vibrates the sassafras weldering welding that rubs, and feasibility has preferably been determined through structure and industrial analysis in the burst position.
The problem that following brief description the present invention is connected with other parts.Referring to Fig. 4, throttle valve is installed universal design that end face 15 can compatible two kinds of throttle valve bodys by adopting five bolts hole; Air inlet pressure sensor mounting flange face 24 equally can compatible two kinds of pressure transducers; Brake boost pump vacuum hose joint 25 satisfies the pressure requirement of brake boost pump by verification experimental verification; Fuel oil piece-rate system interface 16 is on crankcase ventilation system interface 17 next doors, and crankcase ventilation system interface 17 and fuel oil piece-rate system interface 16 are arranged in the another side of pressure stabilizer 18, is exactly with throttle valve the relative opposite side of end face 15 to be installed.The cylinder cap flanged surface 14 of intake manifold is connected with cylinder cap by a rubber gasket, and 40 ones of the bases of intake manifold have fixed support seat 41 to be connected with cylinder body by a support in addition.
