Latest Patents

One of Vroman's latest inventions is the development of methods and systems for operating an adjustable pre-chamber. This invention describes a unique approach for an engine equipped with a pre-chamber ignition system. In this method, a valve is adjusted between the pre-chamber and the main chamber to determine if pre-chamber ignition or direct spark ignition is preferred. This adjustment enables the engine to operate with direct spark ignition under conditions where pre-chamber combustion may lack stability, eliminating the need for additional spark plugs and air injectors.

Another significant patent by Vroman is the automotive combination sensor. This innovation offers systems for estimating EGR mass and air mass during both steady-state and transient operations. By incorporating a combination sensor that consists of a manifold absolute pressure sensing element and a differential pressure sensing element, which both share a common pressure chamber connected to the intake manifold, the invention effectively reduces errors in EGR mass estimation.
