Skoda OCTAVIA 1.4 Petrol 2005 Tiger Hydrogen Engine Carbon Cleaned with the result: Low Idle 0.03% High Idle 0.02% NCT CO2 PASS 10.06.2016
(Irish: An tSeirbhís Náisiúnta Tástála Carranna; abbreviated NCT) is a roadworthiness test, which all cars in Ireland must undergo.
If you failed the NCT Emissions test you should buy a 1 HHO KIT Hydrogen generator for fix CO2 emissions. Drive your car for 1 to 2 days 100 km and then take a re-test. Most Motorists should pass on the 2nd attempt. Watch video and pictures of NCT Exhaust emission PASS.
The vehicle has failed an emissions test or the exhaust emissions are too high as measured by an emissions analyzer.
There are numerous components that if not working properly, can cause high emissions or an emissions test failure. You should read each of the description and operation of the component in the emission control system section of the manufacturer’s manual covering your vehicle in order to gain a working knowledge of each system. These systems are designed to reduce the emissions (as set by NCT emissions standards). If any of these emissions components fail, emissions can increase. Along with these systems, other components such as spark plugs, plug wires, and filters can also increase emissions if defective. Emissions or smog is a generic term used to describe certain harmful gases in the exhaust. Hydrocarbons (HC), Carbon Monoxide (CO) and Oxides of Nitrogen (NOX) are usually measured in an emissions test. The NCT certain limits on each of these harmful gases emitted. Carbon Dioxide (CO2) is also measured but is not considered a harmful gas. When the measured gases from the vehicle exceed the NCT limits, the vehicle fails the emissions test.
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:
