What is an oil catch can and how does it work?
An oil catch can is a device designed to capture and store the blow-by gases and oil vapors that are produced by an engine. These gases and vapors are created as a result of the combustion process and can contain contaminants such as oil droplets, fuel vapors, and other debris. The oil catch can is typically installed in the engine’s crankcase ventilation system and works by providing a separate compartment for these gases and vapors to collect, rather than allowing them to be recirculated back into the engine.
The oil catch can works by using a combination of gravity and airflow to separate the oil and debris from the blow-by gases. As the gases enter the catch can, they pass through a series of filters and baffles that help to remove the oil and debris, allowing the clean gases to exit the can and be recirculated back into the engine. The captured oil and debris are then stored in the catch can, where they can be easily drained and disposed of. By capturing these contaminants, the oil catch can helps to reduce the amount of debris that can enter the engine, which can help to improve engine performance, reduce wear and tear, and prevent damage to the engine’s components.
Why are oil catch cans necessary for turbocharged engines?
Turbocharged engines are particularly prone to oil contamination due to the high pressures and temperatures involved in the turbocharging process.
