How a Crankcase Breather Works How a Crankcase Breather Works
The crankcase breather, located inside the engine, is a pipe which releases gasses trapped in the engine compartment. If the engine is allowed to pressurize then you can lose performance. The car, during its normal function, creates a variety of gasses which can escape the piston rings. The crankcase breather is in place to route these gasses back to the carburetor. The crankcase breather is essentially an environmental addition to avoid releasing gasses into the atmosphere. The article below will explain how the crankcase breather works.
When you open the hood to the car you will need to locate the carburetor. Installed on it will be the crankcase breather. It is screwed in to a port and it is typically round. The look of it varies from model to model. They can easily be replaced, installed or removed completely if that is the choice of the car’s owner.
The purpose of the engine is to create a mini explosion also known as combustion. Air filters through the engine and is mixed with fuel which ignites. Gasses are created from burning fuel and oil.
The gasses created circulate through the engine and enter the crankcase breather. The filter removes debris and routes the gas back to the engine.
