SAN RAMON, Calif., April 29, 2019 – Chevron Oronite announced that it will be sponsoring and presenting at the 74th STLE Annual Meeting and Exhibition, taking place in Nashville, Tennessee, USA, May 19-23, 2019.
Ramoun Mourhatch, technology development formulator, Automotive Engine Oils, Chevron Oronite Company LLC, will be giving a presentation titled, A Comparison of Tribosystems, Wear Mechanism and Lubricant Effects in Silent and Roller Timing Chains, on Tuesday, May 21, 2019 at 10:30 a.m. (during the engine drivetrain session).
“The presence of measurable amounts of soot in modern passenger car engines due to rapid adoption of gasoline and diesel turbocharged direct injection technologies (i.e. TDI and TGDI) appears to result in accelerated chain wear,” said Mourhatch. “The purpose of this presentation will be to share the results of our study, which mapped the tribosystems and lubrication regimes in both types of timing chain; and established the primary wear mechanisms in each case.”
Brendan Miller, senior research tribologist, Fundamental Testing, Chevron Oronite Company LLC, will be giving a presentation titled, Fuel Economy Modeling: Engine-to-Engine Operating Regime Differences, on Wednesday, May 22, 2019 at 11:30 a.m. (during the engine drivetrain session).
“Overall fuel economy performance is dependent on the balance of boundary and hydrodynamic friction within an engine,” said Miller. “During this presentation, I will explain that determination of this balance with respect to engine hardware, operating parameters, and formulation levers within each subsystem of the engine by offering examples generated by a first principles fuel economy model.”
