Especially, the control of automobile exhaust is very strict. So the three-way catalyst has also become a common thing in the car. What is the catalyst of the three-way catalyst in the car? What is the role of the three-way catalyst?<\/h5>\n<h5><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-42027\" src=\"https:\/\/www.chinaputech.com\/wp-content\/uploads\/2022\/11\/20221122144717.jpg\" alt=\"\" width=\"642\" height=\"497\" srcset=\"http:\/\/www.newtopchem.com\/wp-content\/uploads\/2022\/11\/20221122144717.jpg 642w, http:\/\/www.newtopchem.com\/wp-content\/uploads\/2022\/11\/20221122144717-640x495.jpg 640w, http:\/\/www.newtopchem.com\/wp-content\/uploads\/2022\/11\/20221122144717-320x248.jpg 320w\" sizes=\"(max-width: 642px) 100vw, 642px\" \/><br \/>\nWhat is the catalyst of the three-way catalyst in the car?<\/h5>\n<h5>Catalysts are metals platinum, rhodium and palladium, and then one of these substances is sprayed on the carrier, which constitutes the catalyst. Ternary catalyst, is a catalyst that converts harmful gases emitted from the exhaust of a car into harmless carbon dioxide, water and nitrogen by oxidation and reduction.<\/h5>\n<h5>\nA stainless steel box is installed in the vehicle&#8217;s emission system and inside the box is a catalytic purification converter. The catalyst inside the converter is made of a honeycomb-shaped ceramic or metal matrix, and the honeycomb is coated with an active coating consisting of three components: Al2O3, rare earth-based materials and a small amount of precious metals, which are then used to complete the catalysis.<\/h5>\n<h5>\nWhat is the function of the three-dimensional catalytic converter?<\/h5>\n<h5>It converts harmful gases such as CO, HC and NOx into harmless carbon dioxide, water and nitrogen through oxidation and reduction. If the three-stage catalytic converter is damaged, the second stage oxygen sensor above it will not provide correct data to the trip computer, so the mixture concentration will be too lean or too rich.<\/h5>\n<h5>\nAfter these phenomena, it will make the car appear to be difficult to phone, the engine release, driving powerless. And too rich, but also increase fuel consumption, incomplete combustion, spark plug carbon accumulation and other situations, so when the car in the three-way catalytic converter problems, must be timely maintenance.<\/h5>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>In the process of continuous development of science and&#8230;<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[14335],"tags":[],"gt_translate_keys":[{"key":"link","format":"url"}],"_links":{"self":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/42026"}],"collection":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/comments?post=42026"}],"version-history":[{"count":1,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/42026\/revisions"}],"predecessor-version":[{"id":42028,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/42026\/revisions\/42028"}],"wp:attachment":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/media?parent=42026"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/categories?post=42026"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/tags?post=42026"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
