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 surely prevent fuel vapor from being emitted from an intake passage into the atmosphere during the stop of an internal combustion engine. SOLUTION: A shut valve 14 is provided in an upstream side of a throttle valve 12 of an intake pipe 5 and in a downstream side of an air cleaner 13, opened with a signal of ECU, etc., on operating an engine, and closed on stopping the engine to prevent the fuel vapor in the intake pipe 5 from flowing out of the air cleaner 13. The fuel vapor confined in the intake pipe 5 is adsorbed by an adsorbent in a usual canister 2 through a normally opened type bypass valve 8. Although a blowby line 10 is also connected with the intake pipe 5 closed with the shut valve 14, since it is blocked with a normally closed type blowby valve 11 during the stop of the engine, there is no possibility of the blowby gas flowing into the intake pipe 5 to fix the shut valve 14, a throttle-valve 12 or the like.

摘要： PROBLEM TO BE SOLVED: To improve the measurement accuracy of a thermal-resistor current meter. SOLUTION: An arithmetic processing circuit 6 measures the resistance values of cables 23a-23c for measurement, connecting the body 21 of a bridge circuit to flow velocity measuring resistors 22a-22c and the resistance values of the resistors 22a-22c before heating, and sets the resistance value of a variable resistor 213 based on the measured resistance values, so that a prescribed heating rate is obtained. Consequently, the occurrence of measurement errors can be prevented, even if the resistance values of resistance lines 204, except those of the resistors 22a-22c, change due to temperature fluctuations or switching operations of a change-over switch 24, which switches the objects to be measured.

摘要： PROBLEM TO BE SOLVED: To improve efficiency of an evaporative fuel treating device using a purge pump. SOLUTION: Air for purge is supplied by a purge pump 108 to a canister 101, and desorbed fuel is purged to an intake pipe 201 in this evaporative fuel treating device. An ECU 112 intermittently actuates the purge pump 108, so that internal temperature of the canister lowered by latent heat of vaporization during actuation periods of the purge pump 108 is recovered to facilitate desorption in the actuation periods. Real actuation time is shortened, thereby the service life of a motor 7 as a power output section of the purge pump 108 can be extented.

摘要： PROBLEM TO BE SOLVED: To provide a fuel vapor treatment equipment capable of preventing the disordering of an air-fuel ratio in a combustion chamber immediately after the start of purging, and improving the exhaust emission. SOLUTION: This fuel vapor treatment equipment is provided with a purge valve 43 on a connecting part of a purge line 42 and a canister 2, in adjacent to the canister. Accordingly, the canister and the purge line are separated when the purge is stopped, which prevents the fuel vapor from being dispersed to the purge line from the canister. Further as the fuel vapor remaining in the purge line is sucked out by the negative pressure of an intake pipe, the fuel vapor does not retain in a space such as the purge line just before the start of purging, which prevents the disordering of the air-fuel ratio in the combustion chamber immediately after the start of purging.

摘要： PROBLEM TO BE SOLVED: To suppress the emission of fuel steam without increasing a canister capacity, by reducing an emission of fuel steam from a fuel tank, regulating an air-intake from the canister air opening. SOLUTION: One end of a canister 3 filled with activated carbon is connected to a fuel steam passage 2 channeled to a fuel tank 1 whereas the other end is connected to an air-conducting passage 5. An air valve 6 is provided in a midpoint of the air-conducting passage 5, and this is designed that the valve is opened when there is a positive pressure in the fuel tank 1 and closed when it is turned to a negative pressure because of the decrease of inner pressure of the fuel tank 1 to maintain the condition up to a set pressure around the pressure limit for the negative pressure of fuel tank 1. When it reaches the set pressure, the air inducing passage 5 is momentarily released. Raising the negative open valve pressure for the air valve 6 to in the vicinity of pressure limit of the fuel tank 1 minimizes air-intake at compression of steam inside the tank, thereby reducing the emission of fuel steam.

摘要： PROBLEM TO BE SOLVED: To perform the feed of a high oil pressure to a valve timing varying mechanism as an amount of lubricating oil necessary to a lubrication needing portion, such as a bearing part and a valve system is ensured, in a hydraulic control device for the lubricating oil system of an internal combustion engine. SOLUTION: In a lubricating oil passage 54 to interconnect a lubrication oil pump 50 and the lubrication necessary portion of an internal combustion engine, a control valve 70 is arranged in a spot situated downstream from a portion where a high pressure passage 66 to a valve timing control valve 38 is branched. A control valve 70 responds to a pressure in the lubrication oil passage 54 but at a high oil temperature (100 deg.C) or more, at which a lubrication pressure is reduced, and during low rotation (600rpm), a gap G to ensure a minimum lubricating oil amount to the lubrication necessary portion of an internal combustion engine is ensured between a valve element 70-1 and a valve seat 70-2. Thereby, the feed of oil to a valve timing mechanism is effected in priority during a low oil pressure and valve timing switching responsiveness is ensured.
