What Is The Use Of A Kanjo Spec.D Oil Catch/Breather Can?

The oil catch can is an oil/air separator. The oil catch can separate the oil droplets from the air circulating from the engine breather and then through the intake system. The internal combustion systems are imperfect, and the pressure in the combustion chamber will sometimes find its way into the oil pan or the crankcase. It is called the positive crankcase pressure. The pressure must escape through a ventilation system called the positive crankcase ventilation valve. 

The characteristics that keep the engine friction low also do not let the piston rings create a perfect seal against the cylinder wall. Oil droplets are vaporized when the pressurized air mixes with the spinning crankshaft and other engine components. 

The vaporized oil contains contaminants that are produced by combustion. The vaporized oil particles escape through the positive crankcase ventilation valves. The vaporized oil is redirected back into the engine’s intake system and processed through the emission control devices into the exhaust system. The process is necessary to reduce air pollution and abide by the guidelines but hurts the intake system. 


Why Is The Kanjo Spec.D Oil Catch/Breather Can Mandatory For Direct Injection Engines?

Let’s see why the oil catch can is necessary for direct injection engines. In port-injected engines, the fuel is sprayed into the intake manifold, and it works as a cleanser. It washes off the oil and reduces debris build-up. However, direct injection engines shoot fuel directly into the cylinder, and there is no buffer or filter to prevent the debris from getting in and creating a build-up. 

The oil catch can work like a filter, plugging into the hose line to catch the debris before it can reach the engine’s intake manifold. 


How Does A Kanjo Spec.D Oil Catch/Breather Can Work?

The oil catch can supplement the breather hose between the PCV and the engine’s intake system. The breather hose from the PCV is disconnected from the air intake and is replaced or directly connected to the catch can input.

The air travels from the bottom of the catch can through a tube, back to the top of the oil catch can, and towards the outlet passing through a filter. A hose comes from the outlet that completes the circuit and reconnects to the air intake port. When the air passes through the catch can filter, it traps the oil particles and pools them together into larger droplets before falling to the catch can’s bottom. 

The catch cans are fitted with a drain plug to eradicate the oil catchment periodically. For first time installaion, it's recommended to check your catch cans at it's first 500 miles. This will give you an idea of how much oil you are catching. However, the flow, filtration, mounting location, and maintenance requirements differ between car  models. So, to pick the right one, try talking with your mechanic or doing some research.
