Racor Crankcase Ventilation

Racor Crankcase Ventilation

The Problem – Engines Releasing Pollutants Through Unfiltered Breathers Environmental concerns and le gislation to control crankcase emissions have increased significantly. To further reduce the total emissions of engines, in s ome applications it is b ecoming necessary to close the crankcase breather system, routing these gases into the air intake system. Crankcase blow-by is produced when combustion gases under high pressure are blown passed the piston rings into the crankcase. As these blow-by gases pass though the crankcase, they become contaminated. Racor’s Crankcase Ventilation System removes these contaminations. The exhaust can then be allowed to vent to the atmosphere. For applications requiring more stringent emissions requirements, a closed crankcase filter is recommended. In this application, the exhaust from the crankcase filter is routed to the inlet s ide of the turbo. A regulator in the cr ankcase filter controls the vacuum in the crankcase to ensure proper operation. Racor CCV Systems In a robust, compact package, the patented Racor Closed Crankcase Ventilation (CCV)Filter System provides superior oil coalescence and crankcase pressure control under the most severe conditions. The only routine maintenance required for the CCV system is filter replacement. Typical service life of the high-performance filter in diesel applications is 750 hours. Some variations in service life occur depending on load profile, engine wear condition, flow and aerosol mass concentration of crankcase emissions, and soot concentration. How To Select A CCV Assembly: CCV systems are designed to handle various crankcase flow rates up to 50 CFM. Traditionally, the crankcase flow rate can be calculated as follows: rated horsepower ÷ 40 = cubic feet per minute (CFM). This formula can only be used as a guide since recent improvements in piston design have produced engines with higher horsepower and lower blow-by flow rates. The blow-by flow rate of a worn engine, at time of overhaul, is generally double the flow rate when the engine is new. The flow rate of a worn engine is factored into the formula. Note: Specify left or right-hand inlet when ordering.
