Latest Patents

One of Julien's latest patents is focused on a low soot stoichiometric compression-ignition combustion system. This innovative combustion mechanism injects oxygenated fuel into a combustion chamber, where it mixes with intake air to achieve a stoichiometric air-fuel ratio. The system includes an ignition mechanism that ignites the mixture, generating a controlled number of particulates during combustion. Additionally, it features an exhaust gas recirculation (EGR) device that lowers combustion temperatures, resulting in reduced nitrogen oxide emissions. A three-way catalytic converter is also integrated into the exhaust channel to further minimize pollutant emissions compared to conventional systems.

Another notable patent involves particle field imaging and characterization using vertical cavity surface emitting lasers (VCSELs). This apparatus provides multi-beam imaging of particles by generating converging light beams that form a measurement volume within a particle field. The system ensures uniform background illumination and includes imaging optics coupled with a digital camera to capture shadow images of particles. A processor is connected to the camera to analyze the data collected.
