So much effort goes into controlling the exhaust emissions of combustion engine vehicles and this section looks at some of the underlying principles of emission control and the 4 gas analyser.
The 4-gas analyser can provide a window into the combustion chamber and understanding how to interpret its readings is a very powerful skill. This comprehensive and in-depth course is designed to explain how to use it and interpret its results, along with some great diagnostic techniques.
