Infiltration/Inflow (I/I or I&I) is the process of groundwater, or water from sources other than domestic wastewater, entering sanitary sewers. I/I causes dilution in sanitary sewers, which decreases the efficiency of treatment, and may cause sewage volumes to exceed design capacity.
The intake manifold vacuum, with wide open throttle, is lower in these conditions, which causes the PCV valve to open and the crankcase gases flow to the intake system. [13] The greater flow rate of intake air during these conditions means that a greater quantity of blow-by gases can be added to the intake system without compromising the ...
Under the hood, an effective scoop must funnel air into the engine's intake in as short and direct a path as possible, preferably through a tube or channel that is insulated against underhood heat. A scoop may be part of the hood or may be part of the engine's air cleaner assembly, protruding through a hole cut into the bonnet.
Owens-Illinois was a part of the Dow Jones Industrial Average from June 1, 1959, until March 12, 1987. The company was added to the S&P 500 Index in January 2009. Owens-Illinois was one of the original S&P 500 companies in 1957. It was removed in 1987 (after purchase by KKR), added in 1991 and removed again in 2000. [7]
Intake refers to an opening, or area, together with its defining edge profile which has an associated entry loss, that captures pipe flow from a reservoir or storage tank. [1] Intake refers to the capture area definition and attached ducting to an aircraft gas turbine engine [ 2 ] or ramjet engine and, as such, an intake is followed by a ...
The ACIS/TVIS System. Acoustic Control Induction System, or ACIS, is an implementation of a variable-length intake manifold system designed by Toyota.. Simply put, the ACIS system uses a single intake air control valve located in the intake to vary the length of the intake tract in order to optimize power and torque, as well as provide better fuel efficiency and reduce intake "roar".
The Ferrari F40 sports car has "NACA style" side and hood scoops.. It is especially favored in racing car design. [4] [5] Sports cars featuring prominent NACA ducts include the Ferrari F40, the Lamborghini Countach, the 1996–2002 Dodge Viper, the 1971–1973 Ford Mustang, the 1973 Pontiac GTO, the 1979 Porsche 924 Turbo, the Maserati Biturbo, the Nissan S130, and the Porsche 911 GT2.
Most vehicles manufactured from the mid-1970s until the mid-1990s have thermostatic air intake systems that regulate the temperature of the air entering the engine's intake tract, providing warm air when the engine is cold and cold air when the engine is warm to maximize performance, efficiency, and fuel economy.
