Comprehensive Analysis of Carrier Types for Internal Combustion Engine Exhaust Purifiers: Applications from Gasoline Vehicles to General Machinery 1 Introduction Exhaust purification technology for internal combustion engines is a critical means to address emission pollution from motor vehicles and general machinery. The purifier carrier, as the support structure for the catalyst, determines the efficiency and reliability

With growing public awareness of environmental protection, national emission standards for vehicles are becoming increasingly stringent. Since the implementation of China’s National IV emission standards, most diesel vehicles have been required to install SCR aftertreatment systems to effectively reduce pollutant emissions. [Image] In the SCR aftertreatment system, urea solution (hereinafter referred to as urea) plays

Most of our factories possess one particular skill: rather than focusing on perfecting their products, they specialize in driving down prices. This phenomenon is prevalent across many industries. They become complacent over minor gains, and before they realize it, they have orchestrated their own downfall. When prices are driven into the ground and the market

Purpose of Replacing Exhaust Headers An exhaust header paired with a high-flow catalytic converter is an extremely important component among various modification parts. It plays a significant role in unlocking a vehicle’s potential power. Compared to the low-flow, high-cell-density catalytic converters equipped in stock vehicles to meet stringent environmental emission standards, aftermarket high-flow catalytic converters

Diesel Generator Set Exhaust Purification Diesel generator sets, as the current mainstream preferred choice for emergency power sources, have been widely adopted. With the gradual increase in national environmental protection standards for emissions, the installation of exhaust gas purification systems in the exhaust smoke systems of diesel generator sets has become an inevitable requirement. The

Catalytic Converter Working Principles & Performance: Natural Gas (Methane) vs. Methanol Engines under Stoichiometric & Lean-Burn Conditions A detailed comparison of Three-Way Catalytic Converters (TWC) for natural gas (primarily methane, CH₄) and methanol (CH₃OH) engines, covering both stoichiometric (λ≈1) and lean-burn (λ>1) combustion modes. I. Core Differences in Catalytic Requirements Based on Fuel PropertiesProperty Natural

The catalytic converter is a critical emissions control device in a vehicle’s exhaust system. It utilizes precious metal catalysts such as platinum, rhodium, and palladium to convert harmful gases—carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx)—into harmless carbon dioxide, water, and nitrogen‌. Its core working principles include oxidation reactions (converting CO and HC into
