With emerging new vehicle technologies, the current and future vehicles have very low pollutant concentration in their exhaust. To certify such advanced technology vehicles for Type Approval and Conformity of Production (COP) as per present and future emission legislations, new generation emission equipment with better accuracy, repeatability and reliability is required. Hence state-of-the-art emission equipments, which can measure very low concentrations of emissions, are set up in the emission laboratory. Also to ensure the accuracy of measurement the ambient air parameters like temperature, humidity are tightly controlled.
