Title: Innovations by Inventor Shirish S Punde

Introduction

Shirish S Punde is a notable inventor based in Columbus, Indiana, known for his contributions to aftertreatment systems in automotive engineering. He holds a total of four patents that showcase his innovative approach to improving exhaust gas treatment technologies.

Latest Patents

One of his latest patents is an aftertreatment system that includes preheating oxidation and catalyst. This system is designed to treat exhaust gas produced by an engine. It features an exhaust conduit that receives exhaust gas and hydrocarbons from the engine. The system includes a preheating oxidation catalyst and a primary oxidation catalyst positioned downstream of the preheating oxidation catalyst. Additionally, a selective catalytic reduction system is integrated into the exhaust conduit downstream of the primary oxidation catalyst. The system is equipped with a controller that determines the temperature of the exhaust gas at the inlet of the selective catalytic reduction system. If the temperature is below a certain threshold, the controller prompts the engine to provide hydrocarbons to the exhaust conduit. The preheating oxidation catalyst then catalyzes the combustion of these hydrocarbons, raising the exhaust gas temperature above the threshold.

Another significant patent by Punde is an aftertreatment system that also includes a preheating oxidation catalyst. This system comprises an exhaust conduit, a preheating oxidation catalyst, a primary oxidation catalyst downstream of the preheating oxidation catalyst, and a selective catalytic reduction system. The controller in this system is designed to monitor the temperature of the exhaust gas at the inlet of the selective catalytic reduction system. When the temperature falls below a threshold, the controller generates a hydrocarbon insertion signal to increase the exhaust gas temperature.
