Title: The Innovations of Charles F. Hoffman
Introduction
Charles F. Hoffman is an accomplished inventor based in Neshanic Station, NJ (US). He holds two patents that showcase his expertise in the field of motorcycle lubricants. His work has contributed significantly to the understanding and improvement of clutch friction properties and lubricating oils.
Latest Patents
Hoffman's latest patents include a clutch friction test for motorcycle lubricants and a two-cycle lubricating oil. The clutch friction test utilizes a modified SAE No. 2 friction machine to evaluate the clutch friction properties of motorcycle lubricants. This process involves measuring the torque after a break-in period at three temperature points: 30-60°C, 70-90°C, and 110-150°C. The test is conducted over a 10-second period while the speed of the motor driving the clutch plates varies from 0-300 rpm, with the clutch plate pressure held at 50 psi. His two-cycle lubricating oil patent discloses a formulation comprising a high and low molecular weight polybutene polymer, solvent, and mineral oil, which exhibits suitable viscosity and improved smoke performance in the JASO test.
