摘要： An evaporative fuel processing apparatus which can optimally process fuel gas according to navigation information or the like. This apparatus obtains future running information from a navigation system and further predicts an amount quantity of fuel vapor generated in a fuel tank (13) according to the running information. Further, the apparatus determines an amount of fuel vapor to be purged from a canister (14), namely, a valve opening of a purge control valve (142) so that an amount of fuel vapor adsorbed in the canister (14) is not more than a predetermined upper limit and that an amount of fuel adsorbed in the canister (14) after running is almost zero. Thus, an evaporation emission is reduced and the durability of the canister is prolonged by controlling the purge control valve.

摘要： In a remaining fuel amount measuring apparatus for a fuel tank which is suited to the fuel tank designed to suppress generation of fuel vapor, a CPU actuates a piston to supply a prescribed amount of air into a pressure adjusting chamber, thereby increasing the pressure within the pressure adjusting chamber. From the Boyle's law, the increasing rate of air before air supply is inversely proportional to the volume V of the pressure adjusting chamber. Therefore, the CPU, referring to the pressure within the pressure adjusting chamber before and after the air supply, acquires the volume V of the pressure adjusting chamber, and subtracts the volume V of the pressure adjusting chamber from the internal volume of a tank body to acquire the volume of a fuel chamber, i.e. remaining fuel amount.

摘要： The emission control system of the present invention removes the small amounts of polluting gases released from various parts of the automobile. These polluting gases are released from, for example, fuel oozing out from connections of the pipes in the fuel system, lubricating oil oozing out from engine body, and solvents and adhesives remaining in the interior and exterior parts of the automobile. In the emission control system of the present invention, collectors and suction pipes are provided. The collectors are disposed at the parts of the automobile from where the polluting gases are released in such a manner that the collectors enclose these parts. The suction pipes connect the respective collectors to an intake nose of an air cleaner disposed in an intake air passage of the engine. Therefore, the polluting gases released from various parts of the automobile are drawn into the engine through the respective suction pipes before they diffuse into the atmosphere, and are burned in the engine. Thus, according to the present invention, the polluting gases released from various parts of the automobile are prevented from diffusing into the atmosphere.

摘要： A moisture adsorbent (32) for adsorbing moisture in exhaust gas and an NOx adsorbent (34) for adsorbing NOx are disposed in a bypass passage (30) for bypassing an exhaust passage (16) of an internal combustion engine (10). When an adsorption operation to the NOx adsorbent (34) is executed, inflow of the exhaust gas to the bypass passage (30) is allowed until the moisture amount that flows into the water adsorbent (32) reaches an allowable moisture inflow amount. The allowable moisture inflow amount is determined based on a residual moisture amount before the starting of the adsorption operation in the moisture adsorbent (32). The residual moisture amount in the water adsorbent (32) can be determined based on the temperature of the moisture adsorbent (32) at the immediately preceding execution of the purge operation.
