Abstract
The utility model relates to a part of an engine of an automobile, in particular to an air inlet manifold of an engine. The air inlet manifold of the engine comprises air inlet channels and flanges arranged at one ends of the air inlet channels. By using the technical scheme, the other end of each air inlet channel is arranged on a pressure stabilizing box, so that an integrated structure is formed; the pressure stabilizing box is provided with a mounting boss with a hole; the lengths of the air inlet channels are equal; and the pipe diameters of the air inlet channels are gradually reduced from the pressure stabilizing box to the flanges. The air inlet manifold of the engine is skillful in structural design, and has the advantages of high production efficiency and compact integrated structure.
Description
Technical field
The utility model relates to a kind of part of automobile engine, is a kind of engine intake manifold specifically.
Background technique
Gas handling system on motor is made up of intake manifold, throttle body, oily rail assembly and pipe joint, intake manifold is the major part of the gas handling system of motor, be the gas-entered passageway of motor, the required air of engine combustion is entered the air flue of cylinder head by intake manifold by air-strainer.Traditional intake manifold is to separate independently two parts with pressure stabilizer, although also increased air inlet length, but Split type structure has increased number of spare parts like this, as increased connecting bolt and the sealing gasket between manifold and pressure stabilizer, the part of increase can strengthen the cost of motor; The manifold of Split type structure and pressure stabilizer have increased the installing space of part, and in the situation that engine structure is very compact, space can be very limited like this; The manifold of Split type structure and pressure stabilizer have increased assembling intensity, affect Assembling Production beat, reduce manufacturing efficiency.
Model utility content
The purpose of this utility model is to provide a kind of engine intake manifold, has solved the problems referred to above.Its structural design is ingenious, has the advantages such as manufacturing efficiency is high, overall structure is compacter.
The purpose of this utility model is achieved in that this engine intake manifold comprises intake duct, is arranged on the flange of intake duct one end, it is characterized in that: the other end of described intake duct is arranged on pressure stabilizer and is integrally formed structure, and pressure stabilizer is provided with tool hole installation base; Each intake duct equal in length, from pressure stabilizer to flange direction, intake duct caliber dwindles gradually.
Described intake duct is four.
The advantage the utlity model has and positive technique effect are: intake duct and pressure stabilizer are structure as a whole, and have greatly reduced the bulk of part, have reduced number of spare parts, reduce cost of production, reduce assembling intensity, enhance productivity, alleviated the weight of motor.Through the air of air-strainer, carry out of short duration stablizing at pressure stabilizer, enter by air flue in each cylinder air flue of the cylinder head fixing with flange.Pressure stabilizer is class rectangle, can make air-flow evenly produce without eddy current, effectively controls airspeed.Each cylinder has designed individual branches, and airway length is equal, has reached the uniform object of Pressure measurement.Between from pressure stabilizer to cylinder cap, the variable section structure that intake duct is convergent, to ensure that air-flow is more adjacent to tube wall, reduces flow losses, increases the air inflow of motor, and guarantee fuel oil fully mixes with air.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the schematic diagram of main TV structure of the present utility model;
Fig. 2 is the schematic diagram of plan structure of the present utility model.
Description of reference numerals: 1 flange, 2 intake ducts, 3 pressure stabilizers, 4 tool hole installation bases.
Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1 ~ 2.This engine intake manifold comprises four intake ducts 2, be arranged on the flange 1 of intake duct one end, be arranged on the pressure stabilizer 3 of intake duct 2 the other ends, and intake duct 2, flange 1, pressure stabilizer 3 are integrally formed structure.Pressure stabilizer 3 is provided with tool hole installation base 4.Each intake duct 2 equal in length, from pressure stabilizer 3 to flange 1 direction, intake duct 2 calibers dwindle gradually.Pressure stabilizer is combined with intake manifold, makes intake manifold overall structure compacter, has reduced the volume of intake manifold, utilizes air inlet dynamic effect to increase motor at low speed power, the charging efficiency of cylinder while having improved low-speed running.Analyze by CFD, pressure stabilizer of the present utility model has good stream shape.And flow loss is less in air flue, speed, the pressure distribution of each air flue are basically identical, especially in the suction port place of cylinder cap, flow loss minimum.Tool hole (tapped hole) installation base 4 is connected with other part of motor by support, in order to fixing intake manifold.
Claims (2)
1. an engine intake manifold, comprises intake duct, is arranged on the flange of intake duct one end, it is characterized in that: the other end of described intake duct is arranged on pressure stabilizer and is integrally formed structure, and pressure stabilizer is provided with tool hole installation base; Each intake duct equal in length, from pressure stabilizer to flange direction, intake duct caliber dwindles gradually.
2. engine intake manifold according to claim 1, is characterized in that: described intake duct is four.
