Title: Innovations by Jeff Malcolm Travis

Introduction

Jeff Malcolm Travis is an accomplished inventor based in Dexter, MI (US). He has made significant contributions to the field of automotive technology, holding a total of 3 patents. His work primarily focuses on enhancing engine performance and emission control systems.

Latest Patents

One of his latest patents involves a method for controlling the regeneration of an emission control device. This method includes adjusting a post fuel injection amount based on the rate of change of engine torque during Diesel Particulate Filter (DPF) regeneration. Specifically, the adjustment reduces the amount when the rate of change is positive and increases it when the rate of change is negative. Additionally, the method may involve delivering exhaust gas to a turbocharger turbine, an oxidation catalyst, and then to the DPF, with further adjustments based on the thermal inertia of the turbocharger.

Another notable patent focuses on vehicle response during acceleration conditions. This vehicle control method is designed for a powertrain with an internal combustion engine and a transmission featuring a clutch. The method includes transitioning through a lash region of the transmission during clutch slipping conditions in response to a driver tip-in. During this transition, the method first retards ignition timing past maximum torque timing while increasing engine airflow, and then advances ignition timing from the retarded timing while continuing to increase engine airflow.
