Abstract
An air intake manifold for an engine comprises two to six air intake pipes. The air intake manifold is characterized in that pipe joint mounting holes are disposed on the air intake pipe, and a pipe joint which is communicated with the corresponding air intake pipe is fixedly connected with each pipe joint mounting hole. The air intake manifold for an engine is additionally provided with the pipe joints on a pipeline so as to modify the gasoline engine into a dual-fuel engine adopting gasoline and compressed natural gas as fuels, and accordingly emission characteristic and economical efficiency of the engine are improved.
Description
Technical field
The utility model belongs to the parts of internal-combustion engine, relates to a kind of intake manifold of engine, is the improvement of prior art.Be specially adapted to cylinder bore and be 86mm (85～87mm) or 91mm (or 90～92mm), piston stroke is that (85～87mm), the inlet and outlet manifold is in the motor same side, and camshaft is side-mounted, uses in the petrol engine of every cylinder 2 valves for 86mm.
Background technique
The development of World Economics has benefited from the utilization of the various energy.As oil, the extensive use of rock gas coal and nuclear energy equal energy source.And as economic embodiment, the development of automobile industry then mainly has benefited from the utilization of oil.Flourish along with automobile industry, the consumption of petroleum-based energy is increasing, and the world oil storage level is corresponding also in quick minimizing; Simultaneously, global environmental pollution worsens has become world-famous puzzle.In order to alleviate the contradiction between China's oil scarcity of resources and the demand and to help stable development of our long-term sustainable and environmental protection, needing planning and development internal-combustion engine is gasoline and diesel oil with clean alternative fuel to substitute petroleum based fuels.So measure that the utilization of other clean energy resource (as: CNG) is necessitated.Emission performance, the Economy of CNG (that is: compressed natural gas) motor are better than petrol engine.Simultaneously, the China's natural gas resource is abundanter, and the CNG automobile has vast potential for future development.By analyzing bigger 491/4Y, the 486/3Y Engine Series of existing market recoverable amount the technical specifications that install CNG additional are arranged, make it to become and to be necessary with the duel fuel engine that gasoline, CNG act as a fuel so it is carried out the necessary technology transformation.
Fuel requirement and air enter cylinder together through mixing after-combustion, in order to realize that CNG fuel and air pass in and out cylinder simultaneously and motor do not adjusted greatly again, need increase CNG fuel inlet isolated plant at manifold.In the prior art, the use of CNG fuel generally is to increase a fuel supply device at the manifold suction port, and this mode can not accurately be controlled every cylinder fuel respectively, causes influences such as specific fuel consumption height, engine performance deficiency.
Summary of the invention
The purpose of this utility model is intended to overcome the deficiency of prior art and motor spatial constraints, a kind of simple and practical intake manifold of engine is provided, by installing the CNG inlet on each pipeline of original intake manifold additional, make petrol engine install CNG fuel additional, thereby improve the emission performance and the Economy of motor.
Content of the present utility model is: a kind of intake manifold of engine, comprise: suction tude, it is characterized in that: pipe joint mounting hole (4) is arranged on the described suction tude (5), and be fixedly connected with a pipe joint (3) that is connected with suction tude (5) at pipe joint mounting hole (4).
In the content of the present utility model: the quantity of described suction tude (5) is 2-6, is 4 preferably, also can be 2,6 etc.
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) the utility model adopts processing one CNG fuel inlet on the intake manifold pipeline, by pipe joint CNG and air flue pipeline ways of connecting is realized the amount of fuel is accurately controlled, and has improved engine power, moment of torsion, reduces specific fuel consumption; For the bigger 491/4Y of existing market recoverable amount, 486/3Y Engine Series, its inlet and outlet manifold is in the motor same side, and intake manifold adopts the aluminum manifold, and each pipeline connects corresponding each cylinder air flue inlet, air inlet smoothness;
(2) the utility model intake manifold has kept the advantage of original intake manifold pipeline structure, promptly keep the independent air feed of each pipeline, air is introduced cylinder, by intake manifold is added holding pipe joint, on each pipeline, add holding pipe joint CNG fuel is introduced cylinder, thereby satisfied the supply of fuel, realized that petrol engine installs CNG fuel additional, realized existing petrol engine is installed additional the function of CNG fuel; By installing CNG additional, improved the emission performance and the Economy of motor;
(3) the utility model be applicable to cylinder bore be 86mm (85～87mm) or 91mm (90～92mm), piston stroke is that (85～87mm), the inlet and outlet manifold is in the motor same side, and camshaft is side-mounted, the petrol engine of every cylinder 2 valves for 86mm; Simple in structure, cost is low, makes easily, produces easy to install, practical.
Description of drawings
Fig. 1 is main TV structure schematic representation of the utility model embodiment 1;
Fig. 2 is the utility model embodiment 1 a structural representation.
Among the figure: adpting flange, 3-CNG pipe joint, 4-CNG pipe joint mounting hole, the 5-suction tude of 1-air inlet inlet, 2-manifold and cylinder cap junction plane.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of intake manifold of engine, comprise: 4 suction tude, the air inlet of each suction tude 51 one ends (promptly near firing chamber air intake one end) that enter the mouth all have pipe joint mounting hole 4, and are fixedly connected with a pipe joint 3 that is connected with suction tude 5 respectively at each pipe joint mounting hole 4.
During use, 4 suction tude 5 are passed through flange 2 and are connected with the cylinder cap air flue respectively, get final product work.
The present embodiment intake manifold has kept the advantage of original intake manifold pipeline structure, promptly keep the independent air feed of each pipeline, air is introduced cylinder, on each pipeline, add holding pipe joint, CNG fuel is introduced cylinder, thereby satisfied the supply of fuel, realized that petrol engine installs CNG fuel additional, realized existing petrol engine is installed additional the function of CNG fuel;
The utility model is not limited to the foregoing description, and the utility model content is described all can implement and have described good result.
Claims (2)
1. intake manifold of engine, comprising: suction tude is characterized in that: pipe joint mounting hole (4) is arranged on the described suction tude (5), and be fixedly connected with a pipe joint (3) that is connected with suction tude (5) at pipe joint mounting hole (4).
