Publication number: 20080274919Abstract: A method and system to reduce fuel consumption and environmental impact in a two-stroke engine. Fresh system oil having a TBN less than 10 is provided and used in the two-stroke engine to produce partially used system oil. The partially used system oil is withdrawn from the two stroke engine and at least one friction modifier is added to at least some of the withdrawn partially used system oil, wherein the addition of the at least one friction modifier reduces the friction coefficient of the withdrawn system oil, resulting in a system oil having reduced friction. The system oil with reduced friction is combined with partially used system oil remaining in said two-stroke and the combined system oil is used to lubricate pistons of said two-stroke engine.Type: ApplicationFiled: July 10, 2008Publication date: November 6, 2008Inventors: Giuseppe Natoli, Giulio Giovanni Pometto, Alfio Bonciolini, Hans Heinrich Petersen, Jorn Dragsted, Claus Martin Olesen, Klaus-Werner Damm

Publication number: 20080207474Abstract: The present invention provides for a method for detecting leaks in a stuffing box of a two-stroke engine. Blended cylinder oil is produced by blending base fluid, at least one additive and a metal source having a first concentration. The metal source includes metals other than calcium and transition metals. The engine is operated by supplying the blended cylinder oil and a fuel to the engine cylinder. The concentration of the metal source is monitored using x-ray fluorescence spectroscopy (“XRF”) to obtain a second concentration of the metal source. The first concentration of the metal source is compared to the second concentration of the metal source.Type: ApplicationFiled: December 11, 2007Publication date: August 28, 2008Inventors: Klaus-Werner Damm, Richard Leahy

Publication number: 20080153726Abstract: A method for operating a two-stroke engine using low sulfur fuels. Blended cylinder oil is produced by blending base oil and at least one additive where the total base number (“TBN”) of the blended cylinder oil ranges from 1 TBN to 20 TBN. The engine is operated by supplying the blended cylinder oil and a fuel having less than 1.0% sulfur to the engine cylinders. The additive includes a low TBN calcium salts at a weight ratio ranging from 90:10 to 10:90; or any combination thereof. A method for operating a 4-stroke engine using low and high sulfur fuels. Blended oil, having a TBN that is greater than 20 TBN, is produced by blending base oil and at least one additive. The engine is operated by exchanging a low sulfur fuel having less than 1.0% sulfur with a high sulfur fuel.

Patent number: 6457564Abstract: A lubrication system for supplying a portion of the engine lubricant to one or more gear devices driven thereby and return to the engine independent of whether the gear devices are being driven at the time. Thus even when the engine is idling engine lubricant is circulated through the gear devices to maintain the temperature of the lubricant circulating through the gear devices within a relatively narrow temperature range. Also, the lubricant level within the gear devices will be maintained without the need for inspection of the gear devices as long as the engine lubricant level is regularly checked and maintained either manually or automatically. Further, by changing the engine lubricant at regular service intervals or using an automated lubricant change system, the quality and level of the lubricant in the gear devices is also maintained.Type: GrantFiled: December 7, 1999Date of Patent: October 1, 2002Assignee: The Lubrizol CorporationInventors: Klaus-Werner Damm, Fredrick P. Boyle

Patent number: 6412338Abstract: A viscometer for sensing or characterizing the stress required to shear a fluid at a given rate includes a pair of members coaxially mounted for relative rotation. Between the members is an annular gap defining a flow path for the fluid. The flow path is configured such that during differential rotation of the members, fluid is caused to flow through the annular gap that is a function of the differential rotation and the viscosity of the fluid. A sensor measures the torque or torque equivalent required to achieve such differential rotation between the members.Type: GrantFiled: November 29, 2000Date of Patent: July 2, 2002Assignee: The Lubrizol CorporationInventors: Frederick P.

Patent number: 5964318Abstract: A system for measuring the quality and level of lubricant in an engine lubricant reservoir includes a valve for selectively directing a portion of lubricant from the engine through a first conduit for return to the engine or through a second conduit for removal from the engine. Within the first conduit are one or more sensors for sensing the condition of the lubricant passing through the first conduit. The sensors are monitored by a controller which is operative selectively to cause the valve to block the flow of lubricant through the first conduit and direct a portion of the lubricant through the second conduit based on the monitored conditions of the lubricant. Also, the controller directs a supply of fresh lubricant to the engine in response to the lubricant in the engine lubricant reservoir dropping below a predetermined level.Type: GrantFiled: January 12, 1998Date of Patent: October 12, 1999Assignee: The Lubrizol CorporationInventors: Frederick P. Boyle, Klaus-Werner Damm, Gary A. Garvin, Gary L. Orloff
