Where the exhaust emissions are controlled by an advanced emission control system such as a three-way catalytic converter which is lambda-probe controlled: ... exhaust pipe emissions - limit values
- measurement at engine idling speed:
The maximum permissible CO content in the exhaust gases must not exceed 0,5 % vol.,
- measurement at high idling speed (no load), engine speed to be at least 2000 min-1:
CO content: maximum 0,3 % vol. ...
The engine shall be mapped along the full load curve, from maximum no load speed to idle speed, using at least 5 measurement points per 1000 rpm intervals and measurement points within ± 50 rpm of the speed at declared maximum power.
