Claudette Hill was one of many L.A. car owners who had their catalytic converters stolen during a rash of thefts in 2020. Right away, the retired seamstress got the auto part replaced.
A three-way catalytic converter on a gasoline-powered 1996 Dodge Ram Simulation of flow inside a catalytic converter. A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction.
In catalytic converters used on automobiles, the combustion of leaded gasoline produces elemental lead, lead(II) oxide, lead(II) chloride, and lead(II) bromide. Lead alloys with the metals present in the catalyst, while lead oxides and halides coat the catalyst's surfaces, reducing the converter's ability to reduce NOx emissions.
When VCM disengages, the engine then misfires if needing to clear the cylinder of oil. This unique type of oil consumption has led to premature failure of parts like spark plugs, catalytic converters, engine mounts, pistons/rings, and cylinder walls.
Effects of this rich running can include fouling the spark plugs, damaging the catalytic converter, stalling and hesitation when the throttle is opened. One method to avoid this issue is by locating the airflow sensor downstream of the blowoff valve (known as a blow-through setup, as opposed to the traditional draw-through setup). By using a ...
The ECE 15/05 norms (also known as the Luxemburg accord, strict enough to essentially require catalytic converters) began taking effect gradually: the initial step applied to cars of over 2000 cc in two stages, in October 1988 and October 1989. [2] There followed cars between 1.4 and 2.0 liters, in October 1991 and then October 1993.
