- What do catch cans do?
Catch cans are simple devices that are installed to capture oil from the PCV port in a designated container and allow cleaned air to return to the engine. This system is critical to ensure long engine life.
- Does a catch can really work?
Yes. Catch cans work on a simple principle. When gas enters the catch can, the volume dramatically increases, reducing the pressure of the gas. As the velocity of the gas slows, the gas inside the can condenses. The greater the surface area inside the catch can, the more effective the separation of liquid from the gas.
- Why use a catch can?
Consider installing a catch can for a diesel, turbocharged engine to improve its performance. Combustion engines work more efficiently if the air entering the engine for combustion is clean. While reducing emissions and fuel consumption, a catch can will ultimately extend the life of your engine.
- Are catch cans illegal?
Yes! Catch cans are absolutely legal, and on some superbly designed diesel engines, they actually come as a standard feature.
- Does a catch can add horsepower?
No. However, installing a catch can will make sure your engine is highly efficient with a clean intake tract, free of oil. It will prevent high performance vehicles from any damage, such as oil contamination leading to overheating engines.
- What is an oil catch can?
An oil catch can is an oil/air separator that can be installed in vehicles to clean the engine intake air. It can have a simple design as a basic can with hoses attached or may be more advanced, with internal baffling to provide more surface area for oil to condense.
