Latest Patents

One of his latest patents is titled "Model-based control of airpath pressure limits by modulating a turbo charger by-pass valve and a variable-geometry turbine." This invention focuses on the simultaneous or independent control of a by-pass valve and a variable-geometry forced induction component on a combustion engine. It utilizes operational parameters measured by various sensors as inputs to a control module. This innovation prevents sudden loss of power due to low turbine efficiencies during transitions between different operating conditions of engine speed and load. Additionally, it controls engine boost pressure to avoid excessive peak cylinder pressures at high engine speed and load.

Another significant patent by Gao is "Diesel transient combustion control based on intake carbon dioxide concentration." This invention includes an engine control module that determines a target intake carbon dioxide (CO2) concentration. It also features an intake CO2 estimation module that estimates the actual intake CO2 concentration. The engine control module adjusts fuel injection based on the target and actual intake CO2 concentrations, enhancing the overall efficiency of diesel engines.
