Latest Patents

Daniel Van Alstine holds a patent for a "Nonlinear model-based controller for premixed charge compression ignition combustion timing in diesel engines." This invention addresses the challenges posed by advanced combustion modes, such as Premixed Charge Compression Ignition (PCCI). In PCCI, the combustion event initiates without a direct combustion trigger, which is a departure from traditional spark-ignited gasoline engines and direct-injected diesel engines. The absence of a direct trigger necessitates the use of model-based controls to ensure robust management of combustion phasing. Traditional, non-model-based controllers often struggle due to the nonlinear relationships between control inputs and combustion system responses. Van Alstine's nonlinear controller is designed to manage engine combustion timing during diesel PCCI operation by targeting specific values of in-cylinder oxygen concentration, pressure, and temperature during early fuel injection.
