Euro 4 Fits 2015-2018 Ford Fusion 1.5L Turbo Three Way Catalytic Converter Focus

The three-way catalytic converter is named as such because it effectively controls three major pollutants: nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC). It accomplishes this through a series of chemical reactions that take place within its structure.

As the engine's exhaust gases pass through the catalytic converter, the three-way catalyst promotes the oxidation of carbon monoxide and unburned hydrocarbons into carbon dioxide (CO2) and water (H2O). Additionally, it facilitates the reduction of nitrogen oxides into nitrogen (N2) and oxygen (O2) gases through a process called selective catalytic reduction (SCR).

The proper functioning of the catalytic converter is essential for meeting emission regulations and ensuring the vehicle's environmental compliance. By effectively reducing harmful pollutants, it contributes to cleaner air quality and promotes a healthier environment.

In summary, the catalytic converter designed to fit the 2015-2018 Ford Fusion 1.5L Turbo and Focus models is a critical component of the exhaust system that plays a crucial role in reducing harmful emissions. Its three-way catalyst enables the conversion of carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances, ensuring compliance with emission standards and environmental regulations.
