DIRECT MONITORING OF EVAPORATIVE EMISSIONS WITH GASERA ONE SHED?直接監(jiān)測蒸發(fā)排放

Evaporative losses from the fuel system are tested for vehicle certification. GASERA ONE SHED allows direct monitoring of evaporative emissions as part of the qualification testing procedures for vehicles. The GASERA ONE SHED’s photoacoustic technique us approved by the Environmental Protection Agency (EPA) and the California Air Resources Board (CARB).?對燃油系統(tǒng)的蒸發(fā)損失進行了車輛認證測試。GASERA一棚允許直接監(jiān)測蒸發(fā)排放，作為車輛資格測試程序的一部分。美國環(huán)境保護局(EPA)和加州空氣資源委員會(CARB)批準了GASERONE的光聲技術(shù)。
