Title: David Mark Ginter: Patents in Diesel Exhaust Treatment

Introduction

David Mark Ginter is an inventor based in Northville, Michigan, whose work includes technologies for diesel-engine exhaust treatment and fuel reforming. His patent portfolio includes 2 patents, with inventions addressing emissions-system performance and fuel use.

Latest Patents

Ginter’s patent titled “Optimized Rhodium Usage in LNT SCR System” describes reducing rhodium use in lean NOx trap and selective catalytic reduction systems for medium- and heavy-duty trucks. The invention operates inline fuel reformers under steam-reforming conditions to produce reformate with a specified hydrogen content or hydrogen-to-carbon-monoxide ratio. It describes operating temperatures of approximately 500–625°C and fuel-to-air ratios of approximately 1.10–1.40, with the aim of supporting regeneration while limiting rhodium loading in both the fuel processors and the lean NOx traps.

His patent “Fuel Injection Before Turbocharger” concerns a diesel power-generation system with a fuel injector positioned upstream of the turbocharger turbine. Fuel injected into the exhaust manifold can crack at high temperatures, releasing heat and mixing as it passes through the turbocharger. The patent describes potential benefits for reformer operation and also discusses using a manifold fuel injector to provide heat for a diesel particulate filter.

Career Highlights

Ginter’s disclosed inventions focus on components and operating methods for diesel exhaust after-treatment systems. His work addresses fuel reforming, turbocharger operation, particulate-filter heating, and the use of rhodium in emissions-control equipment. He is associated with Eaton Corporation.
