FIELD: filtering devices.
SUBSTANCE: present invention relates to a solid particle filter, in particular to a solid particle filter for use in a system for purifying gasoline engine exhaust. The solid particle filter for use in the system for purifying gasoline engine exhaust has an inlet side and an outlet side. At least inlet side is loaded with synthetic ash. Synthetic ash contains one or more of: aluminum oxide, zinc oxide, zinc carbonate, calcium oxide, calcium carbonate, (mixed) cerium oxide-zirconium dioxide, zirconium dioxide, cerium oxide and hydrated aluminum oxide. Synthetic ash is free from oxides of sulfur, phosphorus, magnesium, manganese and lead.
EFFECT: providing high filtration efficiency and reducing filter back pressure.
