The supply module is responsible for delivering the urea used to reduce nitrogen oxides in the exhaust system. The SCR system helps vehicle manufacturers comply with current and future emission requirements.

It supports the catalyst in a catalytic converter, facilitating chemical reactions by providing a surface for the catalyst to interact with reactants. Commonly used in automotive exhaust systems to reduce harmful emissions.

It heats diesel fuel to prevent gelling in cold temperatures, ensuring smooth engine operation. Commonly used in vehicles and machinery operating in cold climates.

It reduces harmful emissions from vehicle exhaust by converting toxic gases (like carbon monoxide and nitrogen oxides) into less harmful substances (like carbon dioxide and nitrogen) through redox reactions. Commonly used in automotive exhaust systems.

In the presence of catalyst and oxygen, in a lower temperature range (such as 250-400 ℃), reducing agents (such as ammonia, CO or hydrocarbons, etc.) selectively reduce NOx in exhaust to N2 and water, thereby reducing NOx emission.
