Abstract
The utility model relates to a catalytic converter assembly for a gas-fueled automobile. The catalytic converter assembly for the gas-fueled automobile comprises a support fixedly arranged on a main beam of the automobile, a transitional connector fixedly arranged on the support and a catalytic converter. The catalytic converter comprises a cylindrical shell body and end covers arranged at the two ends of the shell body respectively, a flange A and a flange B are arranged on the outer sides of the two end covers respectively, a plurality of mounting holes are formed in the flange B, the flange B is arranged on the transitional connector through a threaded fastener, some cylindrical cordierite containing catalysts is arranged in the shell body in an axial direction, and the diameter of the cordierite is matched with the size of the inner hole of the shell body. The catalytic converter is connected in gas exhaust pipelines and is connected with the two gas exhaust pipelines respectively through the transitional connector and the flange A, combustion tail gas discharged by the automobile flows into the catalytic converter through the gas exhaust pipelines, the tail gas reacts with the catalysts contained in the cordierite to convert part of harmful substances in the tail gas into harmless substances, and the processed tail gas is discharged out through the gas exhaust pipeline connected with the flange A.
Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to a kind of catalytic converter assembly.
Background technique
In recent years, country requires more and more higher to the emission of automobile wastes level, the Abgasgesetz increasingly stringent.Because the restriction in space, the used exhaust silencer of the heavy gas-fueled vehicles of preposition exhaust adopts circular silencing apparatus, and the volume of silencing apparatus is limited, catalytic carrier can't be integrated in silencing apparatus inside.If do not adorn catalytic carrier, Vehicle Emission just can not satisfy the requirement of Abgasgesetz.
Summary of the invention
The utility model provides a kind of natural gas vehicle catalytic converter assembly that is connected in the gas exhaust piping in order to overcome the deficiency of above technology.
The technological scheme that its technical problem that overcomes the utility model adopts is:
This natural gas vehicle catalytic converter assembly, comprise the support that is fixed on the automotive frame, be fixed in transit joint and catalyst converter on the support, described catalyst converter comprises columnar housing and the end cap that is arranged at the housing two ends, the outside of described two end caps is separately installed with flange A and flange B, described flange B is provided with some mounting holes, and it is installed on the transit joint by threaded fastener, be provided with some columniform steinheilites in the described housing vertically, the size of the diameter of described steinheilite and housing endoporus is complementary.
In order to prevent steinheilite play in housing, clamped spacer B between above-mentioned per two steinheilites, clamped spacer A between described steinheilite and the housing.
The beneficial effects of the utility model are: catalyst converter is connected in the gas exhaust piping and is connected with two sections gas exhaust pipings by transit joint and flange A respectively, the automobile burning discharge tail gas by gas exhaust piping flow in the catalyst converter with steinheilite in the catalyst reaction that is embedded make the part harmful matter in the tail gas be converted into innoxious substance, tail gas after the processing is gone out by the emission by exhaust pipe that is connected with farad A, this natural gas vehicle directly is series in the gas exhaust piping with catalytic converter assembly, the small and exquisite easy installation of its volume.
