  • Publication number: 20240060438
    Abstract: A system and method for carbon dioxide capture/storage from exhaust utilizing a carbon dioxide separation membrane which may be prepared in the form of a monolithic structure. The captured carbon dioxide may also be stored in a fluid state as supercritical CO2. An integrated fuel delivery and carbon dioxide unloading system is also disclosed, to remove carbon dioxide from a vehicle for sequestration or other industrial purposes.

  • Patent number: 11522345
    Abstract: A method of assisting ignition of a dedicated exhaust gas recirculation (D-EGR) cylinder in a spark-ignited internal combustion engine. The spark igniter has an internal air passage that receives pressurized air and carries the pressurized air down to an exit port in the vicinity of the spark gap of the igniter.

  • Patent number: 11459939
    Abstract: Methods and systems for reducing the temperature of the charge air provided to a turbocharged internal combustion engine. A supercharger is installed on the air intake path, upstream the turbocharger's compressor. A secondary charge air cooler is installed between the supercharger and the main compressor. This over-compresses the intake air, so that an expansion turbine installed downstream the turbocharger's compressor can cool the charge air and still provide sufficient charge air pressure into the intake manifold.

  • Patent number: 11174780
    Abstract: A method of improving cold starting of an internal combustion engine of a vehicle. The vehicle is equipped with an on-board microwave generation system that generates and delivers microwaves into the combustion chamber of each cylinder via an antenna associated with each cylinder. The microwaves are delivered immediately prior to cold start of the engine, causing the combustion chamber and interior elements of the chamber to be warmed.

  • Patent number: 10859040
    Abstract: A method of providing electrical power to on-board electrical devices of a vehicle. The engine has an EGR (exhaust gas recirculation loop) which may be a high pressure loop, a low pressure loop, or a dedicated cylinder loop. A catalyzed heat exchanger on the EGR loop has a steam reformation catalyst and a heat exchanger. The heat exchanger uses hot exhaust gas from the main exhaust line to heat the catalyst. A methane fuel source adds methane to the recirculated exhaust stream before it enters the catalyst, and the catalytic reaction increases the amount of hydrogen in the recirculated exhaust. The hydrogen is then delivered to a PEM fuel cell.
