摘要： PROBLEM TO BE SOLVED: To provide a measuring device of HC blow by volume without any cost up which is designed to measure HC blow by volume accurately by using density, considering that HC density is not influenced by the humidity. SOLUTION: When a canister 30 adsorbs an HC component vaporizing from vaporized fuel in a fuel tank 20, the HC component blowing through the canister 30 flows into a transfer 40 and flows out together with air as a fluid. Thereupon, a HC densitometer 50 detects the density of the HC component within the fluid above. Then, the volume of the HC component blowing through the canister 30 is measured by calculating with a personal computer 80 based on the density detected as above.

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 provide a gas mixing apparatus for obtaining a satisfactorily mixed gas of the first gas with the second gas without making the size of this apparatus large and to provide a device for evaluating an engine intake system using the apparatus.
SOLUTION: Since pipes 4, 5 for introducing the first gas and the second gas are arranged in the gas mixing apparatus 1 at the respective positions offset from the center of a cylindrical gas mixing chamber 2a, the first gas and the second gas flowing in the chamber 2a are mixed with each other while forming whirling currents. Therefore, the mixing of the first gas with the second gas can be promoted. Since the inside diameter of a gas diffusion chamber 3a is made much larger than those of introduction ports of the first gas and the second gas, the flow velocity of the gas flowing in the chamber 3a from the chamber 2a can be made much lower than those of the gases flowing in the chamber 2a from the introduction ports of the first gas and the second gas. As a result, the time that the gas flowing in the chamber 3a is diffused and mixed can be made longer, the diffusion of the gas can progress and the dispersion of the concentration can be lowered, so that the homogeneously mixed gas can be obtained.

摘要： PROBLEM TO BE SOLVED: To retard the progress of the degradation of an activated carbon by preventing the adsorption of a high b.p. component to a 1st layer of fine pore in the activated carbon. SOLUTION: A layer of a low b.p. hydrocarbon 4 covering the inside surface of fine pores 31 is provided by adsorbing the low b.p. hydrocarbon 4 at least on the inside surface of the fine pores 31 of the activated carbon 3 having many fine pores 31 on the surface. When the activated carbon 3 is used as an adsorbing material for a canister, a hardly releasable high b.p. component is prevented from being adsorbed to the 1st layer to suppress the decrease of the volume of the fine pores due to the deposition of the high b.p. component, thus to sustain the adsorption capacity.

摘要： PROBLEM TO BE SOLVED: To control emission of vapor to atmosphere by lowering generation quantity of the vapor, while securing safety. SOLUTION: An evaporative emission treatment device is provided with a canister 3 which is formed by filling adsorbent for evaporative emissions and the canister 3 has one end connected to an evaporative emission path 2 for communicated with a fuel tank 1 and the other end connected to an air introduction path 32 for communicated with atmosphere. A tank internal pressure valve 21 which is composed of a discharge valve 201, which opens to the evaporative emission path 2 and discharges the evaporative emission 102, when the internal pressure of the fuel tank 1 increases over a prescribed range, and a suction valve 202, which opens the evaporative emission flow path 201 and sucks the atmosphere, when the internal pressure of the fuel tank 1 decreases down the prescribed range, is provided in the evaporative emission path 2 so that the valve opening pressure of the suction valve 202 is set to high. The tank internal pressure is held low in decreasing of the internal pressure of the fuel tank 1 so that the discharge volume of the evaporative emissions from the tank can be reduced.

摘要： PURPOSE:To effectively prevent the fuel temperature rise due to the engine hot air. CONSTITUTION:A partitioning wall is installed in a tank 1 along a tank bottom wall 12a exposed to the hot air of an engine, and the part between the partitioning wall 2 and the bottom wall is formed to a fuel staying space 1a. The space 1a communicates to an upper main tank space 1b having a large capacity by the gap of a drain hole 23 into which a fuel pump 3 is inserted. Since the partitioning wall is constituted of the resin having the superior heat resistance, the fuel temperature in the space 1a having a small capacity is speedily raised to the hot air temperature by the received heat supplied from the engine hot air. Since the received heat quantity of fuel is larger as the temperature difference from the engine hot air is larger, the received heat quantity of the space 1a becomes small at the temperature close to the hot air temperature. Then, the heat quantity which transfers from the fuel staying space 1a to the main tank space 1b reduces, and the hot air temperature rise in the space 1b is suppressed.

摘要： PROBLEM TO BE SOLVED: To early enable warming-up or heating, just after cold starting of an engine.
SOLUTION: A control device 50 selects an engine flow passage 41 by a switching valve 40 in warming-up from the cold starting of the engine 10, and fills hot water stored in a heat storage tank 70 in the engine 10. Next, the warming-up of the engine 10 is performed in a state of stopping the circulation of the hot water filled in the engine 10 by switching the switching valve 40 to an engine bypass passage 43. Thus, the hot water stored in the heat storage tank 70 is filled in the engine 10 just after the cold starting, and the warming-up is advanced in a state of stopping the circulation of hot water in the engine 10 after being filled, and further early warming-up can be attained thereby.
