Oil Carryover Filter Test System

In John Deere machinery, engines are at-tached to an open crankcase ventilation (OCV) system that separates oil from crank-case blowby gases and returns it to the engine. After the oil is filtered out, the resulting expulsion is predominantly water vapor from the combustion reaction in the pistons. Un-der extreme conditions (e.g. idling in -40° C overnight), the water vapor from the engine can freeze around the filter, clogging the system. John Deere engineers are designing OCV systems that can withstand this clogging and operate in freezing temperatures.

In an effort to help John Deere engineers test OCV filters, Diesel Crank-case Solutions designed a portable device to simulate the blowby gases of an engine. The device discharges a replica mixture of air, water, and oil particles that come from an engine. The “blowby” mist goes through a hose into a cold chamber where OCV filters can be tested. It is also adjustable and can simulate several different sizes of engines.


The device will provide a reliable benchmark to test the OCV systems. It will remove the need for large test bays, where the exhaust and blowby of live engines are used to test OCV filters currently. Live engines are cumbersome and inconsistent with one another. Bypassing test bays will greatly increase accuracy in testing. The machine is predicted to be able to last over 24 hours, so OCV filters can be tested continuously with a constant blowby source.
