We posted the article on Wednesday – TOP 10 most popular catalytic converters from gasoline cars. So it’s high time for diesel models.
In the automotive world, catalytic converters from diesel engines occupy a unique place. Due to the specificity of exhaust gases generated by these drive units, catalytic converters in “diesel” cars differ in design and technology from those used in gasoline cars. Their key feature is the use of platinum as the main precious metal, supported by rhodium and, in some cases, small amounts of palladium. Platinum is particularly effective in reducing nitrogen oxides (NOx), which occur in higher concentrations in diesel exhaust gases than in gasoline engines.
It is also worth mentioning the growing role of particulate filters (DPF) in the exhaust system of diesel cars. Modern catalytic converters in these vehicles often integrate nitrogen oxide reduction functions with particulate filtering, which further affects their complexity and market value. The high demand for platinum and the complex design make diesel catalytic converters high value – both in production and on the secondary market.
Below we present the 10 most popular models of catalytic converters used in cars with diesel engines. These are the models you most often search for in our price list.
