Failed Emissions Test?
TIP… Use Cataclean 7 – 10 days (one full fuel tank cycle) prior to scheduling your emissions test.
CATACLEAN has been scientifically proven in both laboratory and expert field testing to reduce emissions by up to 60% (see testing). Even in some of the cleanest cars we have tested, Cataclean has proven itself to further reduce vehicle emissions output.
What does this mean? Our results translate to improved overall engine performance, ability to restore lost fuel efficiency and a reduction in emissions. Even in third world countries, an emission testing has become mandatory as a means of regulating vehicles that are polluting the atmosphere with green house gases. This forces vehicle owners to have emission problems repaired that might otherwise be ignored. So when a vehicle fails an emissions test, most motorists are not exactly overjoyed to learn that repairs are needed. Read More
Diagnosis of high emissions can be an involved process that usually requires special tools and measuring equipment. However, armed with a test report indicating what gases are high can help you determine what systems may not be functional.
If the vehicle has failed as a result of high CO and HC, the CO failure should be diagnosed first. If the "Service Engine Soon" or "Check Engine" light is on it should be diagnosed prior to any emissions diagnosis. CO Failure is the result of an excessively rich air fuel mixture.
The following is a list of the most common causes:
Clogged Catalytic Converter?
TIP…Tap on the underside of a catalytic converter….if it sounds hollow or rattles, it is a sure sign that the noble metal substrate inside the Catalytic converter has disintegrated or broken apart.
Use of CATACLEAN as recommended, will help prevent carbon deposit build up in your catalytic converter. As a result, proper air flow will be maintained which translates into maximum conversion or harmful green house gases and will ensure peak vehicle performance. The catalytic converter is like an after-burner. It oxidizes (burns) any residual fuel vapors (unburned hydrocarbons or HC) in the exhaust. It also burns any carbon monoxide (CO) in the exhaust. The exhaust must meet federal emission standards, and if a problem exists that causes emissions to exceed the federal limits by 150%, the OBD II system is supposed to catch the fault, set a code and turn on the Check Engine light.

Clogged Oxygen Sensor?
TIP…Make certain that your oxygen sensor is working like new….this leads to maximum power and fuel efficiency.
Use of CATACLEAN as recommended, will help prevent carbon deposit build up on your oxygen sensors. As a result, proper air flow will be maintained which translates into maximum performance, fuel economy and reduced emissions. A petrol engine burns petrol in the presence of oxygen. There is a particular ratio of air and petrol that is optimum and that ratio is 14.7:1 (different fuels have different optimum ratios -- the ratio depends on the amount of hydrogen and carbon found in a given amount of fuel). If there is less air than the optimum ratio, then there will be fuel left over after combustion. This is called a rich mixture. Rich mixtures are bad because the unburned fuel creates pollution. If there is more air than this optimum ratio, then there is excess oxygen. This is called a lean mixture. A lean mixture tends to produce more nitrogen-oxide pollutants, and, in some cases, it can cause poor performance and even engine damage.
