Efficient engines and catalytic converters

Oil or antifreeze entering exhaust O2 sensor not operating correctly Road damage to converter Silicone contamination Most, if not all, catalytic converter failures are caused by a problem or malfunction somewhere in the emission system ahead of the converter.

Here are some troubleshooting suggestions: Vacuum test Connect a vacuum gauge to the vacuum on the intake manifold, carburetor, or throttle body. Note the reading at idle. Then raise and hold engine speed at 3, RPM.

The needle will drop when you first open the throttle, but should then rise and level off. If the vacuum reading starts to drop, pressure may be backing up in the exhaust system indicating a blockage somewhere in the exhaust system.

Backpressure test Measure backpressure directly. Or, remove the oxygen sensor and take your reading at its port in the manifold or head pipe. A reading of more than 1.

Back to Small Engine Repair FAQ Table of Contents. Introduction Can you see above the weeds? Most problems with gasoline powered rotary lawn mowers as well as other small engines have simple and inexpensive solutions. Catalytic Exhaust Products manufacture a full line of high flow diesel catalytic converters, as well as exhaust cleaners, purifiers, scrubbers for different types of engines. We offer the widest range of catalytic converters & diesel particulate filter for sale! 2-way catalytic converters are oxidation catalysts. They oxidize CO and HC but do not reduce changing. If the oxygen level in the exhaust stabilizes, the catalytic converter efficiency will drop considerably. In order for a catalyst to best clean up NOx the A/F ratio must be richer than however, NOx emissions from the engine are.

So checking exhaust temperatures front and back of the converter at idle and 2, RPM may not be an accurate way to determine if the converter is working or not.

Watch out for RVT silicone contamination Silicone-based products or Teflon sealants should not be used on any part of the exhaust system. They are not designed to operate at high exhaust temperatures and will out gas, causing damage to O2 sensors. Below are some examples of O2 sensors contamination caused by the use of RTV silicone on exhaust manifold flanges and other components as well as Teflon-type sealants used on O2 sensors.
