Abstract
An engine lubrication system simulating device is provided, having a reservoir configured to contain engine oil. The simulating device may also include an agitation device configured to agitate oil in the reservoir. In addition, the simulating device may include a circulation system configured to circulate oil between the reservoir and a reserve tank of an oil consumption measuring device and maintain a constant level of oil in the reservoir. Further, the simulating device may include an output port configured to facilitate removal of oil from the reservoir at a known, controlled rate and transport it to a location separate from the reservoir and the oil consumption measuring device.
Claims28
An engine lubrication system simulating device, comprising:
- a reservoir configured to contain engine oil;
- an agitation device configured to agitate oil in the reservoir;
- a circulation system configured to circulate oil between the reservoir and a reserve tank of an oil consumption measuring device and maintain a constant level of oil in the reservoir;
- and
- an output port configured to facilitate removal of oil from the reservoir at a known, controlled rate and transport it to a location separate from the reservoir and the oil consumption measuring device.
An engine lubrication system simulating device, comprising:
- a reservoir configured to contain engine oil and be coupled in fluid communication with a reserve tank of an oil consumption measuring device, the reservoir having at least one transparent portion configured to enable viewing of components internal to the reservoir during operation;
- an agitation device configured to agitate oil in the reservoir;
- a circulation system configured to circulate oil between the reservoir and the reserve tank while maintaining a constant level of oil in the reservoir, the circulation system including:
- at least one suction tube having a first inlet positioned at a predetermined height within the reservoir and a suction pump associated therewith, the suction tube being configured to remove excess oil from the reservoir, and
- at least one return tube having a return pump associated therewith and configured to transport oil into the reservoir from the reserve tank;
- an output port configured to facilitate removal of oil from the reservoir at a known, controlled rate and transport it to a location separate from the reservoir and the oil consumption measuring device;
- an electrical heating element configured to controllably heat oil within at least one of the reservoir and the circulation system;
- a second inlet configured to facilitate controlled pressurization of the reservoir;
- and
- a connection tube configured to facilitate equalization of pressure between the reservoir and the reserve tank.
A method of testing an oil consumption measuring device, comprising:
- attaching the oil consumption measuring device to an engine lubrication system simulating device having a reservoir containing engine oil;
- agitating the oil in the reservoir;
- circulating oil between the simulating device reservoir and the measuring device while maintaining a constant level of oil in the simulating device;
- removing oil from the reservoir at a known, controlled output flow rate and transporting the oil to a location separate from the reservoir and the oil consumption measuring device.
