Act or process of expelling the exhaust gases from the cylinder by some special means, as, in many four-cycle engines, by utilizing the momentum of the exhaust gases in a long exhaust pipe.
Removing combustion products from the combustion chamber.
the selective removal of material from the radioactive cloud by inert substances, such as precipitation, introduced into the fireball
is defined as the collection of excess gases from the breathing circuit and removal of these gases to an appropriate place of discharge outside the working environment.
The process of cleaning and removing extinct or outdated name data from the WINS database.
The process of replacement the residual gases by the fresh charge (air), by which the cylinder gets filled with the mixture of them, and some portion of fresh charge is lost to exhaust.
The process of removal of gases or small particles in the atmosphere by uptake (condensation, nucleation, impaction, or coagulation) into larger (cloud or precipitation) particles.
The process of removing burned gases as completely as possible from an engine cylinder before the next change of air (diesel engine) or fuel-air mixture (gas engine) is introduced.
Scavenging is the process of pushing exhausted gas-charge out of the cylinder and drawing in a fresh draught of air ready for the next cycle in automotive usage. This process is essential in having a smooth-running internal combustion engine. By modifying the exhaust system, (i.e. modifying the back pressure) you can in fact detract from the "ideal" scavenging effects, and reduce fuel efficiency and power.
