LV (Linear Velocity) Value

“LV (linear velocity) value” means a value of the exhaust gas flow rate passing through the catalyst blocks (m3/h) per catalyst block’s section (m2) in a normal direction of exhaust gas flow. Therefore, unit of LV value is (m/h). The exhaust gas flow volume is the volume defined at 0°C and 101.3 kPa.
