Abstract

An engine intake manifold is used for reducing the volume of an intake manifold and improving dynamic performance and fuel efficiency of an engine. The technical scheme includes that the engine intake manifold comprises an involute pressure stabilizing cavity, an air inlet connected with an air filter of the engine is arranged on one side of the involute pressure stabilizing cavity, a row of air supply openings in one-to-one correspondence to air intake channels of an engine cylinder cover is arranged on the other side of the involute pressure stabilizing cavity, and a flange connected with the engine cylinder cover is arranged on each air supply opening. The engine intake manifold omits an air intake branch of a traditional intake manifold so that the structure of the intake manifold is simplified and the volume of the intake manifold is reduced, and not only facilitates integral engine arrangement and part assembly, but also is less in pressure loss of air entering engine cylinders from the intake manifold, is higher in air intake efficiency and more balanced in air intake of the cylinders. Besides, the intake manifold is lower in cost and more convenient in processing and installation.

Description

A kind of engine intake manifold
Technical field
The utility model relates to the intake manifold that a kind of four cylinder engine uses, and belongs to technical field of engines.
Background technique
Engine intake manifold is mounted between closure and the cylinder body, is used for air is imported and is assigned to the parts of each cylinder, and efficiency of engine and power output performance are played crucial effects.Existing intake manifold generally reaches a plurality of air intake branches that are connected with pressure stabilizing cavity by the pressure stabilizing cavity that has suction port and constitutes, and each air intake branch is connected with the intake duct that engine cylinder covers.Because air intake branch is longer, it is bigger to take up room, be unfavorable for the assembling of complete machine and component, and air intake branch distortion mode is different with length, cause each cylinder charge same effect of motor poor, directly influenced engine power performance and fuel efficiency, thereby traditional intake manifold can not satisfy the requirement of the power character and the Economy of motor.In view of this, intake manifold reasonable in design, the volumetric efficiency that improves intake manifold and then the consumption of reduction engine fuel, raising power performance are the problems that those skilled in the art need solution badly.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, the engine intake manifold of superior performance.
The alleged problem of the utility model realizes with following technical proposals:
A kind of engine intake manifold, it comprises an involute pressure stabilizing cavity, one side of described involute pressure stabilizing cavity is provided with the suction port that is connected with engine air filter, opposite side is provided with a row and engine cylinder cover intake duct air supply opening one to one, and each air supply opening is provided with the flange that is connected with engine cylinder cover.
Above-mentioned engine intake manifold is provided with a fixed bolt hole between the suction port of involute pressure stabilizing cavity and middle air supply opening.
Above-mentioned engine intake manifold also is provided with canister control valve connecting tube, crankcase ventilation connecting tube, suction pressure temperature transducer, pressurized machine control valve connecting tube and vacuum servo connecting tube on the chamber wall of described involute pressure stabilizing cavity.
The utility model has saved the air intake branch of traditional intake manifold, makes the intake manifold designs simplification, and volume reduces, and not only be convenient to the assembling of complete machine layout and component, and air is littler by the pressure loss that intake manifold enters cylinder, and intake efficiency is higher.Between the suction port of involute pressure stabilizing cavity and middle air supply opening a fixed bolt hole is set, purpose is the air demand of air supply opening in the middle of reducing, and makes each cylinder air inlet balanced more, thereby has improved engine power performance and fuel efficiency.In addition, this intake manifold cost is lower, processes and install more convenient.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the A-A sectional view;
Fig. 4 is the B-B sectional view;
Fig. 5 is the C-C sectional view;
Fig. 6 is the scheme of installation of intake manifold on motor.
Each label is among the figure: 1, canister control valve connecting tube; 2, crankcase ventilation connecting tube; 3-1,3-2,3-3,3-4,3-5, fixed bolt hole; 4, suction pressure temperature transducer; 5, pressure stabilizing cavity; 6, motor; 7, pressurized machine control valve connecting tube; 8, vacuum servo connecting tube; 9-1,9-2,9-3,9-4, air supply opening; 10, suction port; 11, intake manifold.
Embodiment
Referring to Fig. 1~Fig. 6, the utility model comprises the pressure stabilizing cavity 5 of an involute, be provided with suction port 10, air supply opening 9-1,9-2,9-3,9-4 above, each air supply opening is connected with engine cylinder cover by flange, and air supply opening quantity is identical with the quantity of engine cylinder cover intake duct; The fresh air that engine air filter is discharged enters pressure stabilizing cavity 5 through suction port 10, enters each cylinder of motor again through each air supply opening.
Pressure stabilizing cavity 5 of the present utility model has voltage regulation result preferably for gradually putting the formula structure, and can use its special construction to adjust intake efficiency; Each air supply opening flange thickness equates, corresponding motor one, four cylinders of air supply opening 9-1,9-4() far away from suction port 10, rely on the special construction of pressure stabilizing cavity to carry out the wall guiding, can effectively improve one, four cylinder intake efficiencies.Air supply opening 9-2,9-3 are from pressure stabilizing cavity 5 direct air inlets, and air inlet has higher intake efficiency apart from weak point, the hole wall of fixed bolt hole 3-1 gos deep into pressure stabilizing cavity 5 inside, in the pressure stabilizing cavity 5 inner projectioies that form, can reduce the air inlet difference of one, four cylinders and two, three cylinders, improve intake uniformity.The suction port 10 of intake manifold is positioned at the center portion of intake manifold.Be integrated with canister control valve connecting tube 1, positive crankcase ventilation (PCV) connecting tube 2, suction pressure temperature transducer 4, pressurized machine control valve connecting tube 7, vacuum servo connecting tube 8 etc. on the intake manifold.
