  • Advanced combustion fuel compositions
    Patent number: 10760019
    Abstract: Fuel compositions for advanced combustion engines that include a naphtha boiling range portion are provided, where the fuel compositions can have a reduced ignition delay and/or an improved derived cetane number. The improved combustion properties can be achieved by adding a portion of a light naphtha (boiling range) composition to a heavy naphtha boiling range composition. The addition of up to about 10 vol % of a light naphtha composition to a heavy naphtha composition can result in a mixture having a reduced ignition delay relative to the heavy naphtha composition.
    Type: Grant
