摘要： An apparatus and method for use in diagnosing an evaporative emission canister collection and purge system. An EVAP system of a vehicle can be diagnosed through the use of a swellable adsorbent disposed in the system's canister. The swellable adsorbent is expandable upon adsorption of fuel vapors and contractible upon desorption. By sensing the expansion and contraction response, a diagnostic mechanism can determine whether the vapor collection and purge functions are operating properly.

摘要： An evaporative emission control system for a fuel tank of a vehicle includes a diurnal control module coupled to a vapor exhaust line running between the fuel tank and an activated carbon canister. A purge line is coupled to the canister and is open to atmospheric pressure. The purge line includes a breathing loss accumulator that collects fuel vapors expelled from the canister during diurnal thermal expansion. The diurnal control module closes fluid communication between the fuel tank and the canister when the fuel tank is not being refueled to maintain the fuel tank in a pressurized condition and the canister in a non-pressurized condition.

摘要： In a system and a method for purging a vapor storage canister having adsorbed fuel vapor (or hydrocarbon vapor) by drawing air through the storage canister the storage canister being coupled with an engine having a system for controlling the amount of fuel provided to the engine, the amount of fuel vapor in the purge is estimated using a model that predicts fuel vapor concentration in the purge vapor. The engine controller uses the estimated amount of fuel vapor and air brought into the engine from the evaporative vapor storage canister for better control of engine air and fuel during purging.

摘要： A narrow test chamber has at least one heater immersed with its major faces parallel to the fuel surface, part way up the chamber. Heater resistance increases non-linearly as a critical temperature is reached. When the heater is energized, fuel begins to evaporate. Heater temperature remains below the critical temperature until the fuel level drops to or just below the heater level, whereupon heater temperature rises quickly to the critical temperature and heater current drops sharply. The time t1 required to reach this point and the heater current or energy consumed vary according to the fuel distillation Drivability Index (DI). The DI is determined from the measured heater current and t1 or from differential measurement of t1 for two heaters mounted one above the other, by calculation or from a look-up table. The DI value is then used to control engine operation to reduce pollution and improve performance.
