摘要： PROBLEM TO BE SOLVED: To provide a suction device generating vibration of reverse phase at high accuracy so as to be fitted to pressure fluctuation of sucked air in the suction system, reducing noise and enhancing output of an engine.
SOLUTION: A vibration plate 13 is vibrated by compression air delivered from a compression pump 11. Compression air of reverse phase relative to pressure fluctuation of sucked air is delivered from the compression pump 11 by a compression air control part 30 in synchronous to the engine. Therefore, phase and amplitude of the pressure fluctuation generated by the vibration of the vibration plate 13 is controlled at high accuracy fitted to rotation of the engine. Thereby, the pressure fluctuation of sucked air flowing in a suction passage 27 is denied by the vibration of reverse phase generated by the vibration plate 13. As a result, noise of the sucked air is reduced, the pressure of sucked air becomes constant and volume efficiency of the sucked air sucked to the engine is enhanced.

摘要： PROBLEM TO BE SOLVED: To prevent unburnt HC resulting from the adhesion of fuel to the wall surfaces of cylinders or the like from emanating into the atmosphere during cold start.
SOLUTION: Fuel supply is effected by a main injector 31 which injects fuel collected in a fuel tank 4 and a sub-injector 32 which injects the vaporized fuel in the fuel tank 4. The vaporized fuel is continually and stably generated by generating air bubbles using an air bubble generating means 56 immersed in the fuel collected in the fuel tank 4. During a warming process or the like, the fuel supply by the sub-injector 32 which supplies the vaporized fuel containing large amounts of low-boiling-point components is selected to control the adhesion of the fuel.

摘要： PROBLEM TO BE SOLVED: To carry out a good fuel vapor treatment with a simple constitution without using a HC concentration sensor for monitoring a concentration of a purge fuel vapor (purge gas) in heater heating thermostat control. SOLUTION: When the fuel vapor released from a fuel tank 20 and adsorbed and retained on a fuel adsorption layer 35 (35a, 35b) in a canister 30 is purge- controlled by ON/OFF control of a purge valve 23, a heater plate built in the canister 30 is ON/OFF controlled based on a concentration of the purge fuel vapor presumed and calculated accompanying with an air/fuel ratio control of the internal combustion engine. Thereby, a sensor for detecting the concentration of the purge fuel vapor fed out to an intake passage 2 of the internal combustion engine from the canister 30 through purge passages 22, 24 is not required, and thus allowing a good fuel vapor treatment with a simple constitution.

摘要： PROBLEM TO BE SOLVED: To clarify the relationship between a heating value of a heater and the shape of a fuel adsorbing layer 4 to obtain the temperature regulating effect over the whole area of the fuel adsorbing layer 4. SOLUTION: The fuel adsorbing layer 4 formed inside of a canister is defined into an upper adsorbing layer 4A and a lower adsorbing layer 4b by a partitioning plate 13 in which a heater is buried. The relationship between the heating value of the heater and a thickness X of the upper adsorbing layer 4A and the lower adsorbing layer 4B is determined to satisfy that a temperature of a part nearest to a heating face of the heater, of the fuel adsorbing layer 4 is lower than an ignition point of the fuel, and a temperature of a part farthermost from the heating face of the heater is higher than a boiling point of the fuel. Whereby the desorbing performance of activated carbon C can be improved by heating the fuel adsorbing layer 4 by the heater in desorption, and the approximately full amount of the adsorbed fuel vapor can be desorbed. As a result, as the fuel vapor does not remain in the canister, the fuel vapor flowing in adsorption can be surely and completely adsorbed.

摘要： PROBLEM TO BE SOLVED: To detect any leakage of evaporative systems with high accuracy even when a very large amount of fuel remains. SOLUTION: The time required for the pressure in evaporative systems 6, 7, 8, 10 and 11 to drop from a first predetermined pressure P0 to a second predetermined pressure P1 is measured for a state in which a reference orifice 17 as a reference leak hole is included in a leaking part and a state in which no reference orifice is included, respectively. By comparing the required time T2 in the state in which no reference orifice is included with a reference determination time of the required time T1 in the state in which the reference orifice is included, multiplied by a predetermined coefficient, a state of leakage is diagnosed without being affected by the atmospheric temperature or the like. The pressure drop state is adequately indicated even when a very large amount of fuel remains by using the time from the first predetermined pressure P0 to the second predetermined pressure P1 as an index of the pressure drop state.

摘要： PROBLEM TO BE SOLVED: To suppress exhaust of unburnt HC at the time of low temperature start-up of an engine. SOLUTION: A main injector 11 for injecting and supplying fuel in a fuel tank 13 to an engine body 1, and a sub-injector 12 for injecting and supplying fuel in a liquefied fuel recovery container 16 to the engine body 1, are disposed at an intake port of an engine. A canister 26 is connected to the fuel tank 13 through a first evaporation passage 24, and the liquefied fuel recovery container 16 is disposed at an intermediate part of the evaporation passage 24. The liquefied fuel recover container 16 stores evaporated fuel discharged from the fuel tank 13 and liquefied in the first evaporation plassage 24. This stored fuel contains components having low boiling points and easily vaporized, at a large rate compared with fuel in the fuel tank 13. In the low temperature start-up state of the engine and at the time of the fuel quantity in the liquiefied fuel recovery contained 16 exceeding the specified level, the ECU 40 injects to supply liquefied fuel stored in the container 16, to the engine from the sub- injector 12.

摘要： PROBLEM TO BE SOLVED: To provide the device superior in vapor adsorption, capable of loading in a flat space, coping with transitory dischage of a lot of vapor with a low pressure loss, efficiently absorbing vapor. SOLUTION: A container H of a canister 1 is formed in a flat shape in the lateral direction to cross the flow direction of evaporation fuel led into from an inlet port 12, and therein a plurality of adsorption passages 11A-11C having therein activated carbon C are arranged. Since this device can be loaded in a flat space around a fuel tank 2, the low length to the tank 2 is made short, and since the passages 11A-11C are arranged in parallel, the pressure loss is reduced and the device can cope with transitory discharge of vapor of large quantity made with a high adsorption.

摘要： PROBLEM TO BE SOLVED: To realize a fuel vapor treating device with high adsorptive capacity and a low pressure loss structure by introducing fuel vapor in cells having their adsorptive capacity. SOLUTION: The inside space of a container H provided with a fuel vapor introducing passage H1 communicated with the fuel tank and an atmosphere introducing passage H2 communicated with the atmosphere is partitioned in plural cells S1 to Sn in the flow direction of fuel vapor. And adsorptive material layer 1 is formed in each of those plural cells. Respective cells except the last cell Sn are provided with bypass passages 3 each of which communicates a cell located upstream and a cell located downstream and each opening/closing valve 4 for opening/closing those bypass passages. Pressure loss reduction is planned by opening the opening/closing valve 4 by means of an opening/closing valve operator 5 for sending fuel vapor to cell S2 located downstream through bypass passage 3 when the saturation of cell S1 is detected.
