Title: David A. Brass and Diesel Engine Lubricant Innovation.
Introduction
David A. Brass is an inventor associated with East Brunswick, New Jersey. His patent work addresses diesel engine lubricants designed to balance wear protection, soot dispersancy, and emissions-related formulation limits. Brass is associated with Infineum International Limited.
Latest Patents
The supplied information identifies one patent for Brass: “Lubricating Oil Compositions with Improved Wear Performance and Soot Dispersancy.” The invention concerns a diesel engine lubricating oil composition made by combining base oil, a functionalized polymer, overbased magnesium- and calcium-based detergents, and one or more higher- and lower-molecular-weight PIBSA-PAM dispersants, which may be borated.
The composition is specified to have sulfated ash of no more than 1.0 wt.%, kinematic viscosity at 100°C of 5 to 20 cSt, phosphorus of no more than 0.120 wt.%, and sulfur of no more than 0.4 wt.%. It is also designed to achieve a Cummins ISM oil filter delta pressure test result below 30 kPa at 150 hours. The patent further describes methods for preparing and using the composition, improving engine wear performance and soot dispersancy, reducing diesel engine emissions, and producing an additive concentrate. Brass is credited with 1 patent in the information provided.
Career Highlights
Brass’s listed patent reflects work on lubricant formulation for diesel engines. Its combination of performance targets and limits on ash, phosphorus, and sulfur illustrates the technical challenge of developing oils that protect engine components while supporting emissions-conscious operation.
Collaborations
The supplied information names Alec C. Labb as a coworker associated with Brass’s patent work. Infineum International Limited is identified as Brass’s company.
Conclusion
David A. Brass’s identified patent focuses on a carefully balanced diesel engine lubricant intended to improve wear performance and soot dispersancy while meeting defined composition and test requirements.
