Automotive exhaust control means and aftermarket
The control means of exhaust emission of internal combustion engine are divided into three aspects: pre-engine control, in-engine combustion and post-engine treatment. Pre-engine control is mainly to control the quality of oil products and reduce harmful substances. Internal combustion is to impr...Read more -
What is an oxygen sensor
In the 1990s, pollution from cars became a hot topic. Power system sensors used to improve fuel efficiency and reduce carbon emissions have been paid more attention. After decades of development, the power system sensor has become an indispensable part of the automobile electronic control system,...Read more -
About three-way catalytic converters
The exhaust gas from locomotive is one of the main sources of air pollution. The main pollutant of medium and heavy diesel vehicles is nitrogen oxide, whose emission is extremely serious to the ecological environment and human health. Nitrogen oxides in combustion exhaust gases are usually produc...Read more -
What are metal-supported and metal-supported catalyst coatings?
The three-way catalytic converter is generally composed of shell, damping layer, carrier and catalyst coating. The shell is made of stainless steel material to prevent the oxidation skin from falling off and causing blockage of the carrier. The material of the damping layer is generally expansion...Read more -
Factors affecting the normal operation of the three-way catalytic converter and judging whether it is damaged
The conditions of use of catalytic converters are quite strict. First of all, if gasoline or lubricating oil additives are improperly selected, lead-containing fuel additives or engine oil additives with excessive sulfur, phosphorus, and zinc content are used, phosphorus, lead, and other substanc...Read more -
The role of bellows in automobile exhaust system

The main function of DPF
DPF=Diesel Particulate Filter,A device installed in the exhaust system of a diesel vehicle that captures diesel combustion fumes and filters carbon particles to reduce particulate matter (PM) in the exhaust. When there are too many carbon particles captured to a certain extent, the ECU driving co...Read more -
Types of catalytic converters
Catalytic converter components: The catalytic converter consists of a catalyst made of platinum, palladium, rhodium, or a mixture of these two materials. A catalyst is any material that accelerates a chemical reaction without changing its properties. The catalyst is coated on a block of ceramic f...Read more -
Honeycomb ceramic for three way catalytic converter
As a functional porous material, honeycomb ceramic is a new type of structural ceramic product, named for its internal structure similar to the shape of a honeycomb. The evenly distributed honeycomb cross-sectional shape can be divided into hexagonal, square, triangular, circular and other geomet...Read more -
Recycling of three-way catalytic converter
At present, there are two methods of regeneration, namely wet method and fire method. Wet recovery: decompose in alkaline medium with sulfuric acid or sodium hydroxide under pressure to dissolve the carrier. After dissolving, the precious metal remains in the residue, and then leached with chlori...Read more -
