Iranian Researchers Produce Three-Way Catalysts to Reduce Exhaust Emissions from Motorcycles, Vehicles

Engineers of the Iranian company have achieved the formulation of three-way catalysts for motorcycles and vehicles, which can convert the exhaust emissions of these vehicles into harmless substances.

Laden Kamalzadeh, the director of research and development that Iranian factory told Iranian media that the three-way catalyst they produced in their company are used for both cars and motorcycles.

According to the researcher, the three-way catalysts convert hydrocarbon pollutants, carbon monoxide (CO) and nitrogen oxides (NOx) to harmless or less harmful gases such as carbon dioxide (CO.)

Kamalzadeh stated a lot of motorcycle factories get their needed catalysts from their company in order to meet the emissions standards. Meanwhile, she said their company has yet to launch the mass production of the catalysts.

 “During their lifetime, these catalysts reduce up to 90% of exhaust emissions from the engine,” Kamalzadeh said.

She considered the useful life of three-way catalysts which meet the Euro 4 standard to be 100,000 km and according to the Euro 5 standard to be 160,000 km.

“The catalysts needed by car factories for use their vehicles are comply with the Euro 5 standard and have a useful life of 160,000 kilometers,” the engineer continued.

As much as 80% of pollution is caused by cars in big cities, studies show, while eight million people in the world lose their lives as a result of air pollution each year.
