Application of Canisters in ORVR Control

The effect of the vapor generation rate dining ORVR testing is demonstrated in Fig. 26, where the effect of an increase in vapor generation rate from 1.25 g/1 to 1.375 g/1 (5.0 to 5.5 grams per gallon) is presented. The amount of HC adsorbed in the

A vehicle fuel vapor control system must be designed to meet both driving and refueling emission level requirements. Due to the nature of hydrocarbon adsorption, this emission control is a continuous operation. 

The key sources of evaporative emissions during drive cycles are running loss emissions, hot soak emissions, and diurnal emissions.
