Abstract
The invention discloses a dual pre-catalysis exhaust device, comprising four air passages and catalysts. The four air passages connected with an engine cylinder and are formed by four exhaust branch pipes; the catalysts comprise a first catalyst and a second catalyst; the first and the fourth cylinder exhaust branch pipes are converged and then connected with the first catalyst and a first exhaust front pipe; the second and the third cylinder exhaust branch pipes located between the first and the fourth cylinder exhaust branch pipes are converged and then connected with the second catalyst and a second exhaust front pipe; and the inlet of the first exhaust front pipe is connected with the inlet of the second exhaust front pipe through the same flange and the outlets of the first exhaust front pipe and the second exhaust front pipe are converged gathered together. By adopting the dual catalysts and the exhaust front pipes, the invention can avoid exhaust interference of all cylinders in a gasoline engine and improves the performance of the engine, particularly the low-velocity section torque output of the engine. Besides, the tightly-coupled-type dual pre-catalysis configuration can easily meet the increasingly strict emission regulation.
Description
Technical field
The present invention relates to a kind of exhaust manifold for internal combustion engine and catalyst converter device, especially relate to a kind of four-cylinder gasoline engine venting gas appliance.
Background technique
At present, the automobile exhaust manifold mainly contains two kinds of forms: a kind of is as structure as described in the Chinese patent application 02142553.1 automobile exhaust manifold, in four air flues that link to each other with cylinder, the first and the 4th air flue is connected respectively to the conflux both sides of part of exhaust, confluxes and is combined as a whole before the part and be connected to exhaust at the second and the 3rd air flue between the first four air flues; And then outlet connects catalyst converter.Another kind is as structure as described in the venting gas appliance of Chinese patent application CN03101519.0 internal-combustion engine, has a dividing plate in the exhaust duct after each cylinder exhaust branch pipe compiles, and its part is divided into two, and and then outlet connects catalyst converter again.The gas exhaust manifold of these two kinds of traditional forms can not satisfy the requirement of motor to high-performance and low emission.
Summary of the invention
The purpose of this invention is to provide a kind of two venting gas appliance of urging in advance, solve each cylinder exhaust interference of petrol engine and emission compliance problem.Especially improve the output of low engine speed section moment of torsion in the raising engine performance.Simultaneously, the two of close coupled type urge layout can easily satisfy the emission regulation demands of increasingly stringent in advance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of two venting gas appliance of urging in advance, and it comprises four air flues of four exhaust branch pipes formations that link to each other with cylinder, catalyst converter; It is characterized in that: described catalyst converter has two of first catalyst converter and second catalyst converters; Described first be connected first catalyst converter and first exhaust after the 4th cylinder exhaust branch pipe converges before pipe; And second cylinder between the first, the 4th cylinder exhaust branch pipe be connected second catalyst converter and second exhaust after the 3rd cylinder exhaust branch pipe converges before manage; Pipe is connected with same flange with the import of the preceding pipe of second exhaust before described first exhaust, and its outlet pools together.Two at described adpting flange center is the hole independently, and the assembling of whole venting gas appliance is convenient in the existence of its flange.
Further, described every cylinder exhaust branch pipe needs isometric, and concrete length and internal diameter are decided on the target of the arrangement space and the performance that need reach.
The carrier equivalent of described first catalyst converter and second catalyst converter satisfies the requirement of engine low rotation speed air displacement by area; And the technical parameter of two catalyst converters is the same; Each catalyst converter front end awl is gone up a lambda sensor is installed.
Preferably, pipe need be isometric before the pipe and second exhaust before described first exhaust, and its concrete length and internal diameter are decided on the requirement of strength of arrangement space and whole vent systems.
Beneficial effect of the present invention: owing to manage before adopting two catalyst converters and exhaust, can avoid each cylinder exhaust interference of petrol engine, improve engine performance and especially improve the output of low engine speed section moment of torsion.Simultaneously, the two of close coupled type urge layout can easily satisfy the emission regulation demands of increasingly stringent in advance.
Stand test of the present invention shows, can effectively improve before the petrol engine 3000rpm about 8% torque value, and can make the quick ignition of petrol engine catalyst converter.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
