What does crankcase scvenging mean in terms of an automobile ?? .I searched all around the net but didn't get single satisfactory result.
Crankcase scavenging is a process in which the air-fuel mixture is removed from the combustion chamber of an engine by the movement of the piston. It is an important aspect of engine design and is responsible for improving engine efficiency and reducing emissions.
Crankcase scavenging has a direct impact on the performance of an automobile. It helps to improve fuel efficiency, increase power output, and reduce emissions. It also helps to prevent engine knocking and improve overall engine longevity.
There are two main types of crankcase scavenging: positive and negative. Positive crankcase scavenging uses a pump to force the air-fuel mixture into the combustion chamber, while negative crankcase scavenging relies on the natural movement of the piston to draw the mixture into the chamber.
Crankcase scavenging plays a crucial role in reducing emissions from automobiles. By efficiently removing the air-fuel mixture from the combustion chamber, it helps to reduce the amount of unburned fuel and harmful pollutants that are released into the environment.
One of the main challenges with crankcase scavenging is achieving optimal scavenging efficiency. This requires careful design and engineering to ensure that the air-fuel mixture is properly removed from the combustion chamber without causing any unwanted side effects, such as reduced power or increased emissions.
