摘要:
An automatic fuel heating injection valve to be mounted in a combustion chamber of an internal combustion engine. The valve has a fuel evaporating chamber which is communicable with the combustion chamber through a fuel injecting port, a stem valve opening and closing the fuel injecting port, and an actuator which operates the stem valve in response to a pressure prevailing in the combustion chamber. A liquid fuel is sufficiently heated en route to the evaporating chamber by the heat of wall and evaporated through a wick of porous and transudatory material in the evaporating chamber. The evaporated fuel is mixed with combustion gas and fresh air in the evaporating chamber, and the mixture is automatically injected in the combustion chamber.

The invention provides a rodent housing rack that effectively draws the air inside the cages out through exhaust vents.The rodent housing rack comprises: a rack with multiple shelves 2 in which a plurality of cages 3 are arranged and stored, and where the shelves 2 are formed from shelf panels 4; cages 3 that are box-shaped containers having a rectangular-shaped opening that opens up the entire top surface; and an exhaust chamber located on the rear surface of the shelves 2 and that connects all of the shelves 2; and wherein negative pressure occurs inside the shelves 2 and causes air to flow in one-way from the front of the shelves 2 toward the rear; and wherein the space between the opening surface on the top of the cage 3 and the bottom surface of the shelf panel 4 above it is closed off by hanger partitions 5 that close off the top on the left and right sides of the cage and a back panel that comes in contact with the rear of the cage, such that only the front side of the space is open; and exhaust vents 9 are formed in the back panel such that the space above the cage is connected to the exhaust chamber through the vents.
摘要:
An exhaust gas sampling apparatus for analyzing the contents in exhaust gas. The sampling apparatus intakes air from an air intake conduit and mixes the air with exhaust gas taken from an exhaust gas supply conduit. The mixed gas can be sampled in different sampling conduits based upon the type of exhaust gas being examined. The apparatus includes heaters for heating various conduits to prevent condensation from forming within the conduits.

摘要:
A flow rate detector mechanism using variable Venturi therein, comprising: a variable flow rate generator, comprising: a core 11; and a variable Venturi 12; wherein a throat (flow passage) cross-sectional area defined between the core and the venturi is able to be changed by shifting relative positions of the core and the venturi in a direction of axes thereof, and further comprising a flow rate calculation processing portion 30 for calculating a flow rate based on the relative positions in the direction of the axes thereof and for outputting the calculated flow rate, thereby continuously changing the constant flow rate, without occurrence of any disturbance therein. Further, with an exhaust gas sampling method applying the flow rate detector mechanism using variable Venturi, CVS flow rate is changed within the range of the phases of measure modes, so as to make small the difference between the peak dew point in the bag and the final dew point in the bag, as well as to causethe final dew point to approach the temperature at which the bag is kept. Therefore, the dilution ratio of the final dew point is decreased, so as to improve the accuracy in analysis.
