Description
Technical field
The utility model relates to Motor Vehicle and motor car engine draining technology field, particularly a kind of device of processor motor vehicle engine tail gas.
Background technique
The motor car engine exhaust catalytic converter is a critical component that is used for reducing tail gas pollution of motor-driven vehicle; It is converted into harmless nitrogen, carbon dioxide and water through the three-element catalytic reaction with carbon monoxide, oxynitrides, hydrocarbon in the main harmful gas in the motor-vehicle tail-gas.Three-element catalytic reaction is meant and utilizes particular chemical reagent, carries out a series of redox reaction with harmful gas in the motor-vehicle tail-gas, thereby reaches the purpose of purifying motor tail gas.Existing three-way catalytic converter has the Chinese patent " three-way catalytic converter " that a kind of the applicant of being obtains in first to file, and (patent announcement number is: CN201412211Y; The day for announcing is on February 24th, 2010); It includes body and is contained in the purifying agent that is used for three-element catalytic in this body; The front-end and back-end of said body are connected with an adpting flange through an end cap with central through bore respectively, between said purifying agent and said body, laying are housed.The suction port heat radiation when work of this three-way catalytic converter is very fast; The catalytic temperature at catalyzer place is lower; Or the time that reaches desirable catalysis state temperature is longer, so that catalytic conversion efficiency is low, even possibly cause the catalyzed conversion effect at the engine start initial stage not reach standard-required.
The model utility content
The problem that the utility model will solve provides a kind of automotive emission device and motor car engine tail gas catalyzing unit, and this automotive emission device and motor car engine tail gas catalyzing unit can make that the tail gas catalyzed transformation efficiency of engine emission is higher, catalyzed conversion starts faster.
The scheme that the utility model is taked is: this automotive emission device includes motor and motor car engine tail gas catalyzing unit; The suction tude of said motor car engine tail gas catalyzing unit is connected on the said exhaust opening of engine, and the steam outlet pipe of said motor car engine tail gas catalyzing unit connects engine exhaust muffler; Said motor car engine tail gas catalyzing unit includes cylindrical shell and is contained in the catalyzer that is used for three-element catalytic in this cylindrical shell; And inlet end adpting flange; Be provided with by inner core between said barrel front end and the said inlet end adpting flange; Be enclosed within the outer urceolus of this inner core, and be contained in the suction tude that the thermal-protective material between said inner core and the said urceolus constitutes
Because after having adopted such scheme, the utility model compared with prior art has following beneficial effect:
The motor car engine tail gas catalyzing unit can be directly installed in the engine compartment, and catalytic converter can reach normal working temperature very soon, helps catalyst converter and opens combustion, more can improve the catalytic efficiency and the service time of catalyzer, reduces the discharging of dusty gas; Because suction tude has thermal-protective coating outward; Can completely cut off thermal radiation; Make this motor car engine tail gas catalyzing unit not only can be directly installed in the engine compartment; And the heat that it distributes can not cause the inefficacy of peripheral part, and can keep gas flow temperature simultaneously, and what help catalyst converter opens combustion fast.
