What is scavenging and its importance?
Scavenging is the process of removing exhaust gases from the cylinder after combustion and replenishing the cylinder with fresh air. Efficient scavenging is necessary for good combustion of fuel inside the engine cylinder. The passage of scavenge air will also assist cooling of the cylinder, piston and valves.
What are two examples of a scavenger?
Examples of scavengers are vultures, hyenas, ants, ,crows, etc.
Who is a scavenger person?

What is different process of scavenging?
Abstract: The process of simultaneously purging exhaust gas and filling the cylinder with fresh charge for a new cycle is referred to as scavenging. The main scavenging methods are cross scavenging, loop scavenging and uniflow scavenging.
Which type of scavenging is the most efficient?
uniflow scavenging
Cross-flow scavenging, loop scavenging, uniflow scavenging. The uniflow one is the most efficient scavenging system but requires an exhaust valve in the cylinder head. – Uniflow scavenging – A scavenging system where the incoming air enters at the lower end of the cylinder and leaves at the top.
What is meant by perfect scavenging?
(1)Based on Theoretical process: (A)Perfect Scavenging: •Ideally, the fresh fuel-air mixture should remain separated from the residual combustion products w.r.t both mass and heat transfer during the scavenging process.
Is cow a scavenger?
Scavengers are the type of animals that feed on dead and decaying plants and animals. Which of these animals is endangered? Classify according to food-type. tiger, cow, vulture, bacteria, deer, goat, human, fungus, lion, sparrow, buffalo, frog, cockroach, tick.
Are chickens scavengers?
Chickens are scavengers. This is because chickens are willing to eat the remains of an animal that was already dead when they encountered it. Scavengers play an important role in ensuring that the nutrients in a dead organism’s body are cycled within an ecosystem.
Is tiger a scavenger?
Despite the common belief that apex predators like tigers eat only the animals they kill themselves, experts say it is not uncommon for a tiger to take up the job of scavengers. A recent study conducted at the Corbett National Park had found tigers killing elephants, mainly young ones, and eating them too.
What is perfect scavenging?
What is meant by scavenging?
Scavenging is the removal of exhaust gases from an engine cylinder. A part of the compressed air can be easily diverted to ensure complete scavenging of the exhaust gases. Scavenging is the process by which exhaust gases are expelled from the combustion chamber and fresh charge is introduced.
What is scavenging in diesel engine?
Scavenging in Diesel Engines. Scavenging is the process of removing exhaust gases from the cylinder after combustion and replenishing the cylinder with fresh air. Efficient scavenging is necessary for good combustion of fuel inside the engine cylinder. The passage of scavenge air will also assist cooling of the cylinder, piston and valves.

What is scavenging in IC engines?
