There are various types of catalytic converter. A simple ‘two-way’ oxidation cat works to turn carbon monoxide (CO) to carbon dioxide (CO2) and hydrocarbons, which are basically particles of unburnt fuel, to carbon dioxide and water. More advanced ‘three-way’ catalytic converters are fitted to modern cars and these do the above while also reducing emissions of nitric oxide (NO) and nitrogen dioxide (NO2) which together are more commonly known as NOx, a major cause of localised air pollution.
Diesel cars typically have special converters unlimited to cope with the specific emissions from compression ignition diesel engines. These Diesel Oxidation Catalyst units are routinely paired with additional exhaust treatment technologies such as exhaust gas recirculation, Diesel Particulate Filters to trap soot and Selective Catalytic Reduction which uses injections of AdBlue urea solution to remove NOx.
converters unlimited theft
Incidences of converters unlimited thefts from cars showed a dramatic increase in 2019 with the year’s total around 10 times higher than in 2018.
Reports suggest that the growth could be attributed to supply chain issues which have made it harder for dealers to secure replacement catalytic converters through official channels, creating a black market. Historically, however, the greatest driver of thefts has been the overseas markets for the precious metals inside the units. converters unlimited stolen in the UK are often illegally transported abroad and the metals recycled.
