Latest Patents

One of Sinnamon's latest patents is titled "GDCI Transient EGR Error Compensation." This invention focuses on a GDCI engine that recirculates exhaust gases to a combustion chamber using desired early injection parameters for steady-state engine operation. The engine control system detects load increases relative to steady-state operation, addressing the challenge of insufficient recirculated exhaust gases due to transport delays. The invention also involves delaying the last fuel injection during an engine cycle, which results in retarded combustion phasing within the combustion chamber.

Another significant patent is the "System and Method for Estimating Engine Internal Residual Fraction Using Single-Cylinder Simulation and Measured Cylinder Pressure." This estimation apparatus determines the residual burned gas mass fraction of an internal combustion engine without relying on complex calculations of pulsating pressures and flows. Instead, it utilizes measured cylinder pressure and airflow as primary inputs, ensuring accurate simulation states at the time of intake valve closing.
