ABSTRACT:
A coolant filter for a diesel engine having a mechanism for delayed release of chemical additives into the coolant being filtered. The present invention provides a spin-on canister type coolant filter which combines the functions of filtering the coolant of the diesel engine cooling system with the function of adding supplemental coolant additives to the coolant to reduce or eliminate the effects of cavitation erosion caused by vibration of the cylinder liners of the diesel engine. The filter includes a chemical additive cartridge mounted within an outer shell and a filter cartridge mounted about the chemical additive cartridge and inside the outer shell. Coolant to be filtered passes by the chemical additive cartridge, which slowly releases the chemical additive into the passing coolant stream. The coolant containing the chemical additive then passes through the filter to remove relatively large pieces of the chemical additive as well as other debris before exiting the filter for subsequent cooling of the diesel engine. In order to slowly release the chemical additive, the chemical cartridge includes relatively small air vents and outlets and the filter outlet includes a restriction orifice which further slows the release of the chemical additive into the coolant stream.
