Exhaust emissions check

Category: Mechanical repair & servicing

Also known as: emissions test, exhaust gas analysis, smoke opacity test, comprobación de gases, análisis de gases, prueba de opacidad, проверка выхлопных газов

Measuring what comes out of the exhaust with a gas analyser on a petrol engine, or a smoke-opacity meter on a diesel, to see whether the car would pass the emissions part of the ITV and to help find a fault such as a rich mixture, a worn catalyst or a smoking engine. Fixing what the test finds is listed under the matching repair.
