3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Catalytic Converter catalyticconverter
Installed in the vehicle exhaust system, oxidation and (or) reduction, reducing exhaust CO, HC, NOx emissions by catalyst
It means the amount.
3.2
It refers to the installation in the engine compartment, the engine exhaust manifold and catalytic converter composition, and the engine manifold to the respective branch pipes interchange catalyst
Continuous connection length of not more than 500mm inlet end of the catalytic assembly member.
3.3
The test vehicle or engine operation in accordance with certain specified conditions, a certain rate of pollutant emissions before and after the manifold catalytic converter.
Manifold catalytic converter conversion efficiency =
Catalyst inlet pollutant i measured values - catalyst outlet pollutant i measured values
Catalyst inlet pollutant i measured value × 100%
Where.
i --- representing pollutants CO, HC, NOx.
3.4
When the manifold catalytic converter of a pollutant conversion efficiency of 50% corresponding to the catalytic converter inlet gas temperature.
3.5
Located in the center of the carrier means to extend the line from the inlet end face of the catalyst carrier temperature measured at 50mm.
