摘要： A low pressure drop hot film/swirl air flowmeter (10) for an automotive engine is disclosed. The flowmeter includes a main air flow passage (18), a relatively small venturi (20) disposed within the passage for receiving a portion of the air flow, a constant temperature thermal anemometer (48) positioned to sense the air flowing in the throat (44) of the venturi, and a set of swirl vanes (22) operative to impart a swirl to the remainder of the air in the main passage, thereby creating a reduced pressure at the venturi outlet for forced aspiration therethrough without appreciably increasing the pressure drop across the flowmeter. The anemometer includes a bridge circuit (114), one leg of which comprises a resistive sensor (70) within the throat of the venturi. In the preferred embodiment of the invention, an ambient air temperature sensor (72) is included as another of the legs of the bridge to provide temperature compensation for the flowmeter. The anemometer generates an output signal representative of total mass air flow through the flowmeter.

摘要： A low pressure drop air flowmeter (10) for an automobile engine is disclosed. The meter contains a main air flow passage (24), a relatively small venturi (20) to receive a portion of the air flow, pressure ports (98a and 120) for sensing stagnation and static pressure and a set of swirl vanes (22) disposed adjacent the outlet of the venturi and operative to impart a swirl to the remainder of the air in the main passage, thereby creating a reduced pressure at the venturi outlet for amplifying the pressure difference between the stagnation and static pressure without appreciably increasing the pressure drop across the flowmeter. A tertiary passage (28) provides a path of fluid communication between points upstream and downstream of the swirl vanes. This passage includes a flow restricting throat (29) which is manually calibrated during or after assembly. Air exiting the tertiary passage impinges upon the swirl to modulate the vortex velocities. This arrangement results in a fluid flowmeter having a characteristic pressure drop which is less than that of a conventional device, particularly at high flow rates. Also disclosed is a solenoid valve (48) operative in the auto-referencing mode to selectively sample stagnation pressure in the tertiary passage or alternatively upstream of the venturi inlet and signal pressure in the throat of the venturi and generate an electrical output signal as a function of the diffrence between these two pressure signals.

摘要： A low pressure drop air flowmeter for an automotive engine is disclosed. The meter includes a main air flow passage, a relatively small venturi tube receiving a portion of the air flow, a pressure port for sensing stagnation pressure in the main passage, a pressure port for sensing static pressure in the throat of the venturi, and a set of stationary swirl vanes disposed adjacent the outlet of the venturi and operative to impart a swirl to the remainder of the air in the main passage, thereby creating a reduced pressure at the venturi outlet for amplifying the pressure difference between the stagnation and static pressures without appreciably increasing the pressure drop across the flowmeter. Also disclosed is a solenoid valve having a single valving member operative in one position to communicate the stagnation pressure to an absolute pressure transducer and operative in another position to communicate the static pressure to the transducer.

摘要： In the production of break-resistant and abrasion-resistant shaped structures of active carbon, comprising the steps of molding a finely divided, carbon-containing starting material with a binder, hardening the molding, eliminating volatile constituents from the molding composition and activating the moldings at a temperature of about 700.degree. to 1200.degree.C with at least one of steam and carbon dioxide, the improvement which comprises molding the carbon-containing material with a binder comprising a mixture of a phenol and an aldehyde or a condensation product thereof. The carbon-containing starting material may contain volatiles and hardening is effected in two stages with elimination of volatiles, the first stage up to about 150 to 200.degree.C and the second stage up to about 600 to 700.degree.C. The moldings are characterized by a benzene-adsorption capacity in excess of about 25 %, a methylene blue number of at least about 10, an abrasion of less than about 0.6 %, a breakage of less than about 0.8 % and a compression hardness of at least about 15 kp.
