Abstract
A lubrication system for a machine includes a sump to collect a bulk portion of a fluid lubricant and a pump adapted to circulate the lubricant from the sump through a lubricant line to a lubrication target area of the machine. The lubrication system also includes a dip stick defining a first end outside of the machine, a second end immersed in the bulk portion of lubricant, and a lubricant level indicator between the first end and the second end. The lubrication system further includes an additive fixture coupled to the second end of the dip stick. The additive fixture includes at least one additive material section adapted to dissolve in the lubricant to distribute an additive chemical in lubricant circulating through the machine.
Claims12
A lubrication system for a machine comprising:
- a sump to collect a bulk portion of a fluid lubricant;
- a pump adapted to circulate the lubricant from the sump through a lubricant line to a lubrication target area of the machine;
- a dip stick defining a first end outside of the machine, a second end immersed in the bulk portion of the lubricant, and a lubricant level indicator between the first end and the second end;
- an additive fixture coupled to the second end of the dip stick, the additive fixture including at least one additive material section adapted to dissolve in the lubricant to distribute an additive chemical in the lubricant circulating through the machine;
- and
- wherein the additive fixture defines an outer cage having a mesh portion to allow fluid communication of the lubricant between the internal cavity and the bulk portion of the lubricant.
A method of dispensing additive material to a lubricant of a machine comprising:
- providing a dip stick defining a first end outside of the machine, a second end immersed in a bulk portion of the lubricant, and a lubricant level indicator between the first end and the second end;
- securing an additive fixture to the second end of the dip stick, the additive fixture including at least one additive material section adapted to dissolve in the lubricant in the bulk portion of the lubricant;
- and
- inserting a replacement additive material section into an internal cavity of the additive fixture to replenish the at least one additive material section;
- and
- wherein the additive fixture defines an outer cage having a mesh portion to allow fluid communication of the lubricant between the internal cavity and the bulk portion of the lubricant.
An engine for a motor vehicle comprising:
- at least one combustion cylinder within a cylinder block;
- a reciprocating piston arranged to cycle within each of the combustion cylinders to generate an engine torque;
- a lubrication system arranged to circulate a lubricant about components of the cylinder block;
- a sump to collect a bulk portion of a fluid lubricant;
- a dip stick defining a first end outside of the engine, a second end immersed in the bulk portion of the lubricant, and a lubricant level indicator between the first end and the second end;
- an additive fixture coupled to the second end of the dip stick, the additive fixture including at least one additive material section adapted to dissolve in the lubricant to distribute an additive chemical in the lubricant circulating through the machine;
- and
- wherein the additive fixture defines an outer cage having a mesh portion to allow fluid communication of the lubricant between the internal cavity and the bulk portion of the lubricant.
