A carbon ignition temperature depressing agent is disclosed along with a method of regenerating an automotive particulate trap using the ignition temperature depressing agent. The agent is effective to promote oxidation of on-board collected carbonaceous particles extracted from the automobile exhaust. The agent comprises (a) an organometallic compound that upon heating (the combustion process of the engine) forms a readily reducible metal oxide which when finely divided promotes a carbonaceous ignition temperature in the range of as low as 450°F. and up to as low as 675°F., and (b) an aerosol-promoting liquid carrier effective to form a fine mist with the organometallic compound when sprayed, the carrier having a boiling point in the range of 176°-302°F. (80°-150°C.). The organometallic compound is one or more metal octoates having the metal selected from the group consisting of copper, nickel and cerium. The organometallic compounds are readily soluble and stable in the fuel supply used with an internal combustion engine such as an automotive diesel engine. The mixture is used in a volume amount of 10-50 milliliters per gallon of fuel or the organometallic compound is present in an amount of at least 0.15-0.5 gm/gal of fuel. The organometallic compound is proportioned to the carrier in a ratio of 1:2 to 1:10. The aerosol-promoting liquid carrier is selected from the group consisting of hexane, pentane and toluene and is effective to promote a droplet size for said mixture when sprayed of substantially less, on average, of one micron.

A carbon ignition, temperature-depressing agent for addition to the fossil fuel supply of an internal combustion engine and effective to promote oxidation of collected carbonaceous particles extracted from the exhaust gas of the engine, the agent consisting of: (a) a metal octoate organometallic compound that upon experiencing the combustion process of the internal combustion engine forms a first metal oxide readily reducible upon reheating by said exhaust gas to a second metal oxide of lower oxygen level, which second metal oxide promotes oxygen transfer and thereby a carbonaceous ignition temperature in the range of 450°-675°F. (250°-307°C.); and (b) an aerosol-promoting liquid carrier effective to form a fine mist with the organometallic compound and fuel supply when sprayed for initiating said internal combustion, said carrier having a boiling point in the range of 176°-302°F. (80°-150°C.).
