Abstract
The utility model provides an intake manifold of a dual-fuel automobile engine and is used for solving the dual-fuel function of the intake manifold. The intake manifold comprises four parallel intake branch pipes; and after modification, each intake branch pipe is provided with a natural gas joint, and the natural gas joints on all intake branch pipes correspond to each other. In the intake manifold, the natural gas joints are arranged at the upper part of the intake manifold and communicated with a natural gas supply system, so that natural gas can be led in an intake manifold system of the engine; and furthermore, the positions of the natural gas joints are reasonably designed, so that the axis lines of the joints are arranged in parallel with an upper intake passage of the intake manifold, and further the utilization ratio of fuel and the whole working efficiency of the engine are fully improved. By the modification, a single-fuel supply system of the intake manifold can be changed into a dual-fuel supply system; and the two fuel supply systems of the engine can be freely switched by external elements and electrically-controlled equipment.
Description
Technical field
The utility model relates to a kind of automobile component, and particularly a kind of dual-fuel automobile intake manifold belongs to technical field of automobile engine.
Background technique
Automobile inlet manifold is between closure and engine air admittance door, it will give each cylinder by the air distribution that closure imports, with the indoor burning of participation engine combustion after the fuel-oil atmozation that sprays into, intake manifold plays crucial effects to the working efficiency and the power output performance of whole engine.At present, based on the scarcity day by day of petroleum resources and improving constantly of environmental protection requirement, safety, energy-saving and environmental protection have become the theme of current development of automobile, and motor realizes that bifuel system is the trend of social development, also is the embodiment of High-Tech result.Rock gas at home and abroad is extensive use of as the fuel of motor car engine, and its remarkable result aspect " energy-saving and emission-reduction " is subjected to vast use client's favorable comment.Because use the fuel difference, the structure of engine intake manifold is also different, therefore, be necessary to improve the structure of existing intake manifold, satisfy the demand of dual-fuel automobile intake manifold gas handling system.
The model utility content
The utility model is used to solve the defective of above-mentioned prior art and a kind of dual-fuel automobile engine intake manifold that can be applicable to fuel oil, rock gas is provided.
The alleged problem of the utility model solves by the following technical programs:
A kind of dual-fuel automobile engine intake manifold comprises four air intake branches arranged side by side in the formation, its specialization is: described each air intake branch is provided with the rock gas interface, the rock gas interface position correspondence on each air intake branch.
Above-mentioned dual-fuel automobile engine intake manifold, described each rock gas interface lays respectively at each air intake branch top, and each rock gas interface axis is parallel with the intake duct on each air intake branch top respectively.
Above-mentioned dual-fuel automobile engine intake manifold, described each rock gas jointing is provided with the attaching nut.
The utility model is at the dual-fuel automobile engine demand, structure to the available engine intake manifold is improved, the rock gas interface that is communicated with natural gas supply system is set on intake manifold top, thereby rock gas is imported in the engine intake manifold system.In order to reach the fuel availability maximization, the utility model also reasonably designs the position of rock gas interface, makes the axis of this interface parallel with intake manifold top intake duct, with the utilization ratio of abundant raising fuel and the whole work efficiency of motor.Through above-mentioned improvement, can satisfy intake manifold and change dual fuel supply system into by single-fuel system, can realize freely switching of two kinds of fuel supplies of motor by external component and control panel.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the B portion partial enlarged view of Fig. 1;
Fig. 3 is that the A of Fig. 1 is to view;
Fig. 4 is the C portion partial enlarged view of Fig. 3.
Label is as follows in the accompanying drawing: 1. air intake branch, 2. rock gas interface, 3. attaching nut, 4. intake manifold top intake duct, 5. cylinder body.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 4, intake manifold described in the utility model is made of four air intake branches arranged side by side 1, be provided with rock gas interface 2 on the top of each air intake branch, rock gas interface position correspondence on each air intake branch, for ease of being connected, be provided with attaching nut 3 at each rock gas jointing with natural gas supply system.
Referring to Fig. 3, the selection of above-mentioned rock gas interface 2 positions is extremely important, the rock gas interface need take into full account the active position of fuel gas supply in cylinder system, and it is the shortest to guarantee that just fuel gas supply arrives the distance of cylinder body, when rock gas enters air intake branch simultaneously and the intake duct angle the smaller the better.The utility model is arranged on as shown in the figure air intake branch 1 top with the rock gas interface, and each rock gas interface axis is parallel with the intake duct 4 on each air intake branch top respectively.In Fig. 3, what dotted arrow was represented is the trend of fresh air in intake manifold, solid arrow representative be trend after rock gas enters air intake branch, the air inlet angle of rock gas is consistent with the flow direction of fresh air, can not hinder flowing of fresh air because of the adding of rock gas gas, thereby when fresh air and rock gas flow to cylinder body 5 places by the rock gas jointing, can not influence the gas handling system of whole motor.
The utility model intake manifold is supplied with by original single-fuel system and is changed the bifuel system supply into, realizes the function of mixed motivity type intake manifold, and when motor used fuel oil, available plug sealed the rock gas interface.
Claims (3)
