Title: Ted E Stewart: Innovator in Auxiliary Power Systems Introduction Ted E Stewart is an accomplished inventor based in the United States, known for his innovative contributions to auxiliary power systems for large diesel engines. With a focus on enhancing engine efficiency and reducing emissions, Stewart has developed systems that significantly improve the operational capabilities of locomotives and other heavy machinery. Latest Patents Stewart's latest patents include a "System And Method For Supplying Auxiliary Power To A Large Diesel Engine." This invention provides a solution for supplying auxiliary power, allowing for the shutdown of large diesel engines in various weather conditions. The system features an auxiliary power unit composed of a secondary engine coupled to an electrical generator. An automatic control system is designed to shut down the primary engine after a period of idling, while the auxiliary power unit supplies electrical power for heating and air conditioning. In cold weather, it maintains the primary engine's coolant and lube-oil warm to facilitate a smooth restart. Conversely, in warm weather, the unit provides power for air conditioning and other hotel loads. Another notable patent is the "Auxiliary Power Unit Exhaust System And Method For A Locomotive." This invention focuses on reducing engine emissions in locomotives by directing exhaust from the auxiliary power unit into the primary engine's air intake system. The APU can be selectively operated based on the locomotive's current operating conditions, contributing to a more environmentally friendly operation.
