  • Internal combustion engine with cooling assist system for manifold intake temperature reduction
    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.
    Type: Grant

  • FISCHER-TROPSCH DERIVED HEAVY HYDROCARBON DILUENT
    Publication number: 20150144526
    Abstract: The invention provides a process for making a heavy hydrocarbon feed pipeline transportable, said process including blending the heavy hydrocarbon feed with a diluent including a hydrocarbon stream having at least 0.5% by mass of a C4 or lighter hydrocarbon component, said diluent having less than 2% by volume aromatics, wherein the viscosity of the heavy hydrocarbon feed and diluent blend is below 500 cSt at 7.5° C. which is within pipeline transportable limits.
