Care Tips - What is a Breather? |
|
The breather typically refers to a component of the engine's
crankcase ventilation system. The breather is designed to allow the
escape of gases and pressure that build up inside the engine
crankcase.
The engine crankcase is the lower part of the engine block where the
crankshaft is located. As the engine operates, it generates gases
and fumes due to the combustion process and internal friction. These
gases, along with some amount of oil mist, can accumulate in the
crankcase, leading to increased pressure. If this pressure is not
released, it can cause various issues such as oil leaks, decreased
engine performance, and increased wear on engine seals and gaskets.
The breather is usually a small valve or vent located on the
engine's valve cover or oil filler cap. Its purpose is to allow the
excess gases and pressure to escape from the crankcase and into the
intake manifold. This process is known as crankcase ventilation.
By connecting the breather to the intake manifold, the excess gases
are reintroduced into the engine's combustion chambers, where they
can be burned along with the air-fuel mixture. This helps prevent
pressure buildup in the crankcase and reduces emissions.
In summary, a breather in a car is a component of the crankcase
ventilation system that allows the escape of gases and pressure from
the engine's crankcase, helping to maintain proper engine
performance and reduce emissions. |
