ABSTRACT:
A method for testing catalytic converters is disclosed that uses optimum engine settings to determine the operational efficiency of catalytic converters. The method consists of the steps of: pre-setting the engine until it is within manufacturers operating specifications; and then injecting a subsidiary air-fuel mixture into the intake manifold which is supplied from an external source from the internal combustion engine; then adjusting the subsidiary air-fuel mixture until the exhaust gasses produced by th e internal combustion engine are equal to about: 14.7 percent Carbon Dioxide, 0.0 parts per million Hydrocarbons, and between about 1.0 and 1.4 percent Oxygen; and then finally reading the output of carbon monoxide produced by the engine when the percentage of gasses produced in proportions listed above are achieved. This test uses standard automotive test equipment that is now used for emission's testing throughout the United States. A method of testing a vehicle's oxygen sensor is also disclosed. This method uses a subsidiary air-fuel mixture to adjust that air-fuel mixture of the engine from full rich to full lean and then reading the output voltages from the oxygen sensor at the full rich and full lean points. Finally, a method of cleaning the combustion chamber is also disclosed that cleans the engine by injecting a cleaning solvent by remote elements through the intake manifold of the engine.
