\nA GPF, also known as a PPF (petrol particulate filter) or OPF (otto particulate filter), is an emissions control device designed to reduce particulate emissions from gasoline direct injection (GDI) engines.
\n\u200b
\nSimilar to diesel particulate filters (DPFs), GPFs have a wall-flow honeycomb structure made from ceramic cordierite, designed to filter the finer particulates found in petrol exhaust gases.
\n\u200b
\nThe shift to reduce CO2 emissions from vehicles has led to the replacement of traditional port fuel injection (PFI) petrol engines with GDI engines, offering better fuel economy without sacrificing performance.
\n\u200b
\nHowever, GDI engines can produce particulate matter due to shorter air or fuel mixing times, which GPFs effectively filter out.
\n\u200b
\nThis technology ensures that vehicles meet particulate number (PN) emissions standards under all driving conditions, which is especially important for vehicles type-approved under Real Driving Emissions (RDE) conditions.
\n\u200b
\nAs exhaust gases pass through a GPF, they are forced through the channel walls of the honeycomb structure.
\n\u200b
\nThe trapped particulates are reduced to carbon dioxide, while unwanted hydrocarbons, nitrogen oxides, and carbon monoxide are converted into smaller amounts of carbon dioxide, nitrogen, and water.
\n\u200b
\nGPFs require high temperatures to perform effectively, which petrol engines naturally provide, allowing trapped particulates to be carbonised.
