Description
Technical field
The utility model relates to automobile technical fields, more particularly to a kind of automobile exhaust gas processing apparatus.
Background technique
It is energy-saving and environmental protection that current motor-dom, which mentions most words, for the environmental protection being directed to, both at home and abroad all again
New, more stringent automobile emissions standards are promulgated, to control pollution of the vehicle exhaust to natural environment to the maximum extent.When
The preceding domestic state's 6b discharge standard promulgated is referred to as standard the harshest in automobile history, in addition to the optimization of engine body performance,
Matching and exploitation to exhaust gas aftertreatment system is full of challenge.
Gasoline state 6b discharge standard also adds granule number requirement, simultaneously in addition to adding sternly to tail pipe gaseous pollutant limit value
The OBD diagnosis of after-treatment system is required higher.Commonly single ternary catalyzing unit technology path has been unable to satisfy discharge and has wanted state V
It asks, grain catcher is considered as solving the important path of state 6b discharge, but the use of grain catcher may bring system to carry on the back
Pressure is high, regeneration is difficult, arresting efficiency is low, grain catcher low-pressure end hose falls off the problems such as can not diagnosing, how Proper Match
Entire after-treatment system, it will the key as Project Success.
Utility model content
In view of the above situation, it is necessary to provide a kind of matching the reasonable exhaust aftertreatment dress that can satisfy state 6b discharge
It sets.Specific technical solution is as follows:
A kind of automobile exhaust gas processing apparatus, including sequentially connected gas exhaust piping, ternary catalyzing unit, bellows and gasoline
Grain trap；Lambda sensor and post oxygen sensor before being equipped with before and after the ternary catalyzing unit are caught in the diesel particulate
The front end of storage is equipped with temperature sensor, and differential pressure pickup is respectively connected to before and after the diesel particulate trap by pressure difference pipe
End；The temperature sensor, preceding lambda sensor, post oxygen sensor connect electronic control unit with differential pressure pickup signal.
Further, the ternary catalyzing unit to supercharger outlet end is provided with heat shield and heat-preservation cotton, can be effective
Temperature loss behind reduction whirlpool；Ternary catalyzing unit is mounted on close to the position of booster exhaust outlet, to obtain higher temperature, is guaranteed
High transformation efficiency of the ternary catalyzing unit to gaseous pollutant.The outer surface of the ternary catalyzing unit is also equipped with heat shield and heat preservation
Shell bring temperature loss can be effectively reduced in cotton.
Further, the diesel particulate trap has TWC coating, in addition to exhaust particulate arresting efficiency can be improved
Outside, secondary treatment can also be carried out to gaseous pollutant, under high-speed high-load operating condition more to the transformation of gaseous pollutant
It is obvious；Grain catcher is mounted under automobile chassis, is convenient for arrangement, due to farther out from supercharger outlet, in exhaust pipe
Exhaust temperature reduces, and reduced velocity flow, exhaust back pressure can reduce, while the arresting efficiency of grain catcher can also increase substantially,
The grain catcher of coating, which is arranged in chassis lower part, can get 90% or more particle capture efficiency.The diesel particulate is caught
Storage, outer surface are provided with heat shield, can effectively avoid the high temperature that grain catcher is generated by regeneration, light below chassis easily
The risk of combustion things.
In addition, bellows is mounted between ternary catalyzing unit and grain catcher, it is disconnected to can effectively reduce exhaust hot end bracket
Split risk；Forward and backward lambda sensor is mounted on before and after ternary catalyzing unit, and electronic control unit (ECU) is fed back by forward and backward lambda sensor
Oxygen signal accurately controls the burning of engine, guarantees the good former row of engine；Temperature sensor is mounted on grain catcher
Front end, differential pressure pickup are respectively connected to diesel particulate trap front and back end by pressure difference pipe, and electronic control unit (ECU) can pass through this
The temperature and pressure difference signal of two sensor feedbacks can identify the tired carbon state of grain catcher, and pass through control engine
It burns and provides optimal regeneration condition to grain catcher, oil consumption caused by blocking to avoid frequent regeneration or grain catcher increases
Add and complains after sale.
Further, the differential pressure pickup is double absolute pressure force snesors, can export a trap high pressure side pressure simultaneously
Power, low pressure end pressure and poor three signals of high and low pressure side pressure, can effectively solve a trap differential pressure pickup low-pressure end in this way
The OBD that interface falls off diagnoses problem.
The utility model has the beneficial effects that vehicle discharge can be made to reach state's 6b emission level, and electronic control unit can be passed through
(ECU) rationally control grain catcher regeneration, makes complete-vehicle oil consumption be optimal level.
