Abstract
A durable automotive exhaust catalytic converter is used for solving the problem that gaskets of catalytic converters are easy to be damaged. The durable automotive exhaust catalytic converter comprises a catalytic converter cylinder and a ceramic carrier disposed in the cylinder, a gasket is arranged between the cylinder and the carrier, buffer pads are arranged at two ends of the carrier after the catalytic converter is modified, the buffer pads are mesh structures wound with stainless steel wires, the profile of each buffer pad is annular, a step is arranged in an inner bore of each buffer pad, and the inner opening end of each buffer pad is abutted with the gasket while the outer opening end of the buffer pad covers at the edge of the carrier. The buffer pads additionally arranged at two ends of the carrier of the catalytic converter can not only affect circulation of exhaust gas flow of an engine but also prevent the gas flow impacting the gasket directly, thereby being capable of prolonging service life of the gasket and preventing broken gaskets blocking the carrier. In addition, the buffer pads can also prevent the ceramic carrier from directly colliding with front and rear connecting end cones of the catalytic converter when the ceramic carrier is loosened after being positioned, thereby having protection functions.
Description
Technical field
The utility model relates to a kind of automobile-used parts, especially for the durable Exhaust Gas Catalytic Converter for Automobiles of engine exhaust manifold assembly, belongs to automobile harness technical field.
Background technique
Engine exhaust manifold assembly is the automobile exhaust system critical piece, and its inlet end is connected with motor, and the outlet side is connected with outlet pipe.The core component of exhaust manifold assembly is an exhaust catalytic converter, and catalytic converter is made up of cylindrical shell and the liner and the ceramic monolith that are installed in the cylindrical shell.Ceramic monolith costs an arm and a leg, and scribbles noble metal platinum on it, and it is worked under 800-1000 ℃ temperature.Produce in the engine working process air is had the gas of pollution such as nitrogen oxide, carbon monoxide etc. through catalytic converter the time, be converted into innocuous gas such as CO2, H2O through chemical reaction with the precious metal of carrier and discharge.The habitual packaged type of catalytic converter is to be encapsulated in the catalytic converter housing after ceramic monolith is wrapped up by liner at present, relies on the location of gasket compression power realization to ceramic monolith.There is certain drawback in this kind structure, when exhaust when the carrier, the direct impact pad of air-flow, of a specified duration can cause the liner breakage, the broken liner obstruction carrier that minces causes ventilation not smooth.Under the direct impact of high temperature gas flow, the yielding contraction of liner causes the ceramic monolith location loosening, and then moves axially with air motion, bumps with front and back connecting end awl, damages ceramic monolith.
The model utility content
The utility model is used to overcome the defective of above-mentioned prior art and a kind of durable Exhaust Gas Catalytic Converter for Automobiles that prolongs liner working life, improves the ceramic monolith reliability of positioning is provided.
The alleged problem of the utility model solves by the following technical programs:
A kind of durable Exhaust Gas Catalytic Converter for Automobiles, it comprises the catalytic converter cylindrical shell and is positioned at the ceramic monolith of cylindrical shell, be provided with liner between described cylindrical shell and the carrier, its specialization is: described carrier two ends are provided with cushion pad, described cushion pad is the web frame that Stainless Steel Wire twines, its gabarit is shaped as ring-type, and its endoporus is provided with a stage, and cushion pad internal orifice end docks with liner, the collar extension end covers carrier edge.
Above-mentioned durable Exhaust Gas Catalytic Converter for Automobiles, described cushion pad thickness and liner thickness coupling, the height H 1 at cushion pad position between ceramic monolith and cylindrical shell is 9.5 millimeters, and the height H 2 that cushion pad collar extension end covers the carrier edge position is that 4 millimeters, thickness B are 4.3 millimeters.
The utility model has carried out following improvement at the fragile problem of exhaust catalytic converter liner in the present engine exhaust manifold assembly: cushion pad is set up at the carrier two ends in catalytic converter, described cushion pad is wound in reticular structure by Stainless Steel Wire, its resistance to high temperature is good, can see through air-flow, also have certain elasticity.Neither can influence the circulation of engine exhaust air-flow behind the use cushion pad, avoid the direct impact of air-flow again, therefore the working life that can improve liner, prevent that broken liner from stopping up carrier liner.In addition, cushion pad can also avoid itself and catalytic converter front and back connecting end awl that direct collision takes place when become flexible the ceramic monolith location, plays a protective role.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial enlarged view of Figure 1A portion;
Fig. 3 is cushion structure schematic representation (not in scale).
Each label is as follows in the accompanying drawing: 1. catalytic converter cylindrical shell, 2. liner, 3. cushion pad, 4. carrier.
Embodiment
Referring to Fig. 1, the utility model constitutes the ceramic monolith 4 that comprises catalytic converter cylindrical shell 1 and be positioned at cylindrical shell, and liner 3 is coated on outside the ceramic monolith and compresses, and ceramic monolith length will be longer than liner, at the ceramic monolith two ends cushion pad 3 is set.
1-3 with the aid of pictures, described cushion pad 3 has gas permeability and good heat-resistance suction for the web frame that Stainless Steel Wire twines.The gabarit of cushion pad is shaped as ring-type, and its endoporus is provided with a stage, during the encapsulation catalytic converter, cushion pad internal orifice end is docked with liner 2, cushion pad collar extension end covers carrier edge, to prevent air-flow liner is directly impacted, and buffering is to the jerk of ceramic monolith.
Referring to Fig. 2, cushion pad thickness and liner thickness coupling, the size H1 at cushion pad position between ceramic monolith and cylindrical shell is 9.5 millimeters, and the height H 2 that cushion pad collar extension end covers the carrier edge position is 4 millimeters, and thickness B is 4.3 millimeters.
The utility model when encapsulation, according to existing technology ceramic monolith, liner are packed in the catalytic converter cylindrical shell earlier, and then cushion pad is pressed into from the cylindrical shell two ends.
