摘要： PURPOSE:To avoid enlarging the size of a canister and prevent suction of excessive evaporated fuel into the intake pipe of an engine. CONSTITUTION:Evaporated fuel in a fuel tank 6 reaches a storage tank 3 positioned below activated carbon 2 through a vapor line 7, and about the half is then liquefied and fed into a pressurized chamber 41 through an introducing passage 30. At starting an engine, the evaporated fuel is sucked into an engine intake pipe 12 through purge lines 15, 16. Negative pressure of the intake pipe is introduced to a back pressure chamber 54, and a piston 51 locates at the right retreated end. When the negative pressure in the intake pipe is reduced by accelerating the engine, the piston 51 is advanced to the left by spring force, and the volume of the pressurized chamber 41 is reduced, a check valve 14 is pushed to open, and the liquefied fuel is returned to the fuel tank 6. Consequently, about the half of evaporated fuel is returned to the tank as liquefied fuel, hence a large sized canister is unnecessary to be provided, diffusion of fuel is prevented, and with suction of excessive fuel into the intake pipe are prevented.

摘要： PURPOSE:To prevent the rise of the fuel temperature in a tank and improve the evaporation emission by installing an opening/closing valve in a bypass passage for allowing the upstream side of a delivery pipe to directly communicate to a pressure adjusting, detecting the fuel temperature in the delivery pipe, and controlling the opening of the opening/closing valve. CONSTITUTION:A pressure adjusting valve 2 for returning the excessive fuel into a fuel tank 3 is installed on the downstream side of a delivery pipe 1 for feeding the fuel supplied from a fuel pump 8 into the fuel injection valve of an internal combustion engine, and an opening/closing valve 5 is interposed in a bypass flow passage 4 for allowing the upstream side of the delivery pipe 1 to directly communicate to the pressure adjusting valve 2, and a valve driving means 7 which closes the opening/ closing valve 5 when the fuel temperature detected by a means 6 for detecting the fuel temperature in the delivery pipe 1 is over a certain value, while opens the opening/ closing valve 5 when the fuel temperature is below a certain value is installed. Since, when the fuel temperature in the delivery pipe 1 is below a certain value, the opening/ closing valve 5 is opened, and almost all the fuel is returned into the fuel tank 3 from the pressure adjusting valve 2 without passing through the delivery pipe 1, and the temperature rise of the fuel in the tank is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a cooling system of an internal combustion engine capable of accurately detecting boiling of cooling water.
SOLUTION: This cooling system of an internal combustion engine circulates cooling water in a cooling water pipe conduit and inside the engine by using an electric water pump. A part of the cooling water pipe conduit is provided with a water level detecting means for detecting the water level of the cooling water. For example, the water level detecting means can be provided in a reserve tank for accumulating the cooling water. When the cooling water boils, the water level of the cooling water rapidly rises. A boiling detecting means detects the rising rate of the water level of the cooling water, and detects boiling of the cooling water based on the detected rising rate.

摘要： PROBLEM TO BE SOLVED: To provide a fuel vapor supply device of a low cost for supplying fuel vapor to an engine while maintaining a fuel vapor concentration in a fuel tank in an almost saturated state.
SOLUTION: A fuel pump 12 is received in the fuel tank 10 and supplies fuel in the fuel tank 10 to a fuel injection valve 3 through piping 200. The piping 200 is branched in the fuel tank 10 and an electromagnetic valve 14 is installed in a branch pipe 202 branched from the piping 200. A nozzle is provided on the tip of the branch pipe 202. When the fuel pump 12 and a pump 20 are operated and the electromagnetic valves 14, 22 are opened, the fuel discharged by the fuel pump 12 is injected into the space of the fuel tank 10 from the nozzle of the branch pipe 202. The pump 20 is operated so that the fuel vapor in the fuel tank 10 passes through the electromagnetic valve 22 and is supplied into a suction pipe 4 downstream of a throttle device 6.

摘要： PROBLEM TO BE SOLVED: To control diffusion of evaporated fuel in a canister during the decrease of fuel temperature when an engine is stopped and prevent the occurrence of a trouble, such as blow-by of evaporated fuel. SOLUTION: A canister 10 is connected to a fuel tank 5 through a first evaporation passage 8 and a tank internal pressure regulation valve 11 is disposed in the evaporation passage 8. An atmosphere port 13 to introduce outside air is formed in the canister 10 and an electromagnetically-driven atmosphere intake valve 14 is disposed at the tip part of the atmosphere port 13. An ECU 20 controls opening and closing operation of the atmosphere intake valve 14 so that an internal pressure in a tank is fluctuated with a given width in a negative pressure region during the decrease of fuel temperature when an engine is stopped. In this case, through opening of the atmosphere intake valve 14, high speed outside air flows in the canister 10 and this constitution performs back purge of evaporated fuel and narrows an evaporated fuel diffusion layer in the canister 10.

摘要： PROBLEM TO BE SOLVED: To provide simple structure of a fuel vapor processing device in which oil feeding register is small and has good adsorption ability at low cost. SOLUTION: Ends of a canister 4 are respectively connected to a vapor passage 3 communicating with a fuel tank 1 and an intake pipe negative pressure introduction passage 6 communicating with an intake pipe 5 of an internal combustion engine, and the other end is connected to an atmospheric air introduction passage 7. An atmospheric air valve 8 is provided in a midway of the atmospheric air introduction passage 7. The atmospheric air valve 8 communicates with the intake pipe 5 by a first negative pressure passage 61, and communicates with a oil feeding passage 2 which supplied the fuel tank 1 with fuel by a second negative pressure passage 21. At the time of operating an internal combustion engine, the atmospheric air valve 8 is opened by an intake air pipe negative pressure introduced via the first negative pressure passage 61 to introduce atmospheric air from the atmospheric air introduction passage 7 to the inside of the canister 4. At the time of oil feeding, valve opening pressure is reduced using a feeding oil negative pressure introduced via the second negative pressure passage 21 thereby reducing an oil feeding register. The valve opening pressure can be set great by using the feeding oil negative pressure, whereby the adsorption ability is improved.

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.
