Title: Roy Christopher Fonseca: Innovator in Locomotive Technology
Introduction
Roy Christopher Fonseca is a notable inventor based in East Peoria, IL (US). He holds a total of 6 patents that showcase his innovative contributions to locomotive technology. His work focuses on enhancing the efficiency and functionality of diesel-electric locomotives.
Latest Patents
One of Fonseca's latest patents is the Dual Engine Locomotive. This invention features a diesel-electric locomotive equipped with two separate engine systems: a large engine system and a small engine system. The power output from these systems can be combined to drive the locomotive's traction motors. When low power is needed, only the small engine operates. For higher power requirements, the large engine is utilized. In cases of maximum power demand, both engines work together to provide the necessary output. A unique control strategy ensures smooth power delivery, even if one engine fails or starts unexpectedly.
Another significant patent is the System for Starting Power Systems with Multiple Generator Units. This control system is designed for starting power systems that consist of multiple power modules. For instance, in a multi-engine generator set switcher locomotive, the control strategy determines whether to start an engine using air or electric power. It starts only one engine at a time to prevent overloading the air or electric sources. The strategy also prioritizes using air starters to preserve the electric starter motor.
