The three way catalytic converterscontain precious metals that serve ascatalysts, promoting chemicalreactions to convert the exhaustgasses without affecting the metals.The catalytic converters are referredto as three-way catalysts, since theyact on HC, CO, and NOx.Replacement units must be originalAcura parts or their equivalent.The three way catalytic convertersmust operate at a high temperaturefor the chemical reactions to takeplace. They can set on fire anycombustible materials that comenear them. Park your vehicle awayfrom high grass, dry leaves, or otherflammables.A defective three way catalyticconverter contributes to air pollution,and can impair your engine’s per-formance. Follow these guidelines toprotect your vehicle’s three waycatalytic converters.Always use unleaded gasoline.Even a small amount of leadedgasoline can contaminate thecatalyst metals, making the threeway catalytic convertersineffective.Have your vehicle diagnosed andrepaired if it is misfiring, back-firing, stalling, or otherwise notrunning properly.Keep the engine well maintained.Three Way Catalytic Converters536THREE WAY CATALYTIC CONVERTERS11/07/20 19:10:39 31SJA670_541
