Ram-air intake on a Kawasaki ZX-12R. A ram-air intake is any intake design which uses the dynamic air pressure created by vehicle motion, or ram pressure, to increase the static air pressure inside of the intake manifold on an internal combustion engine, thus allowing a greater massflow through the engine and hence increasing engine power.
Ford — Dual-Stage Intake (DSI), on their Duratec 2.5 and 3.0-litre V6s, and it was also found on the Yamaha V6 in the Taurus SHO. The Ford Modular V8 engines and the V6 Cologne use either the Intake Manifold Runner Control ( IMRC ) for four-valve engines, or the Charge Motion Control Valve ( CMCV ) for three-valve engines.
Inside the airbox of an Alfa Romeo Montreal Motorcycle airbox on a V-2 engine. An airbox is an empty chamber on the inlet of most combustion engines. It collects air from outside and feeds it to the intake hoses of each cylinder. Older engines drew air directly from the surroundings into each individual carburetor. Modern engines instead draw ...
During this compression period, fluids can be pumped or, if they are gaseous fluids, compressed. Gerotor pumps are generally designed using a trochoidal inner rotor and an outer rotor formed by a circle with intersecting circular arcs. [1] A gerotor can also function as a pistonless rotary engine. High-pressure gas enters the intake and pushes ...
Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere. Manifold vacuum is an effect of a piston's movement on the induction stroke and the airflow through a throttle in the intervening carburetor or throttle body leading to the intake manifold. It is a ...
An intake (also inlet) is an opening, structure or system through which a fluid is admitted to a space or machine as a consequence of a pressure differential between the outside and the inside. The pressure difference may be generated on the inside by a mechanism, or on the outside by ram pressure or hydrostatic pressure .
Otto cycle pressure–volume diagramThe idealized diagrams of a four-stroke Otto cycle Both diagrams: the intake (0-1 and colored green) stroke is performed by an isobaric expansion, followed by an adiabatic compression (1-2 and colored orange) stroke.
The pump's air intake is filtered by a rotating screen or the vehicle air filter to exclude dirt particles large enough to damage the system. Air is delivered under light pressure to the injection point(s). A check valve prevents exhaust forcing its way back through the air injection system, which would damage the pump and other components.
