Environmentally friendly acid neutralizing full flow cartridge

An environmentally friendly acid neutralizing filter cartridge for mounting in a cartridge mounting body of an engine oil circuit for filtering particulates and neutralizing acid in oil, the filter cartridge comprising:

• a support housing adapted to be mounted in the cartridge mounting body, the support housing comprising substantially no metal parts such that the filter cartridge can be incinerated;
• a full flow particulate filter arranged in the support housing;
• a bypass particulate filter arranged in the support housing;
• a bed of acid neutralizing particles contained in the support housing;
• a predetermined primary flow path defined through the filter cartridge passing through the full flow particulate filter and bypassing the bed of acid neutralizing particles;
• a predetermined bypass path defined through the filter cartridge passing, in sequence, through the bed of acid neutralizing particles and the bypass particulate filter;
• further comprising a constriction arranged to create a pressure differential across the bed of acid neutralizing particles and the bypass particulate filter for propelling oil therethrough;
• and
• wherein the predetermined bypass path also passes through the full flow particulate filter.

An environmentally friendly acid neutralizing filter cartridge for filtering particulates and neutralizing acid in oil, the filter cartridge comprising:

• top and bottom end caps;
• a generally cylindrical full flow particulate filter secured axially between the top and bottom end caps;
• a reactor body extending axially between the top and bottom end caps, the reactor body comprising a reactor chamber and a venturi conduit, the reactor chamber having at least one reactor inlet port and at least one reactor outlet port, the venturi conduit including a constricted portion, the at least one outlet port arranged relative to the constricted portion such that when fluid flows through the venturi conduit, fluid is drawn through the at least one reactor outlet port;
• a bed of acid neutralizing particles in the reactor chamber between the at least one reactor inlet port and the at least one reactor outlet port;
• and
• a second filter arranged downstream of the bed of acid neutralizing particles for preventing acid neutralizing particles from exiting the filter cartridge during use.

An environmentally friendly acid neutralizing filter cartridge for filtering particulates and neutralizing acid in oil, the environmentally friendly acid neutralizing filter comprising substantially no metal parts such that the support housing can be incinerated, the filter cartridge comprising:

• top and bottom plastic end caps, the bottom end cap defining a main outlet;
• a generally cylindrical full flow particulate filter having opposed ends potted into the top and bottom end caps respectively;
• a plastic reactor body having opposed ends potted into the top and bottom end caps respectively, the plastic reactor body arranged generally concentric within the generally cylindrical full flow particulate filter such that an annular collection chamber is defined therebetween, plastic reactor body including an annular outer wall portion, a central tube portion arranged generally concentric inside the annular outer wall portion to provide a reaction chamber therebetween, and a spacer portion, the central tube portion have a top opening spaced axially from the top end cap and a bottom opening communicating with the main outlet, the spacer portion defining a radially extending fluid passageway connecting the annular collection chamber with the top opening, the annular outer wall portion defining at least one reactor inlet port, the central tube portion defining at least one reactor outlet port, and wherein a constricted portion is arranged along the central tube portion, the at least one reactor outlet port arranged along the constricted portion such that when fluid flows through the center tube portion, fluid is drawn through the at least one outlet port;
• a bed of acid neutralizing particles in the reactor chamber between the at least one reactor inlet port and the at least one reactor outlet port;
• and
• a bypass filter in reaction chamber between the bed of acid neutralizing particles and the at least one reactor outlet port.
