  • Exhaust manifold constructions including thermal barrier coatings for opposed-piston engines
    Patent number: 11098634
    Abstract: An exhaust manifold assembly with a thermal barrier coating for an opposed-piston engine reduces heat rejection to coolant, while increasing exhaust temperatures, fuel efficiency, and quicker exhaust after-treatment light-off. The exhaust manifold assembly can include a coating on the inside surface of the manifold assembly. The coated exhaust manifold assembly can ensure structural robustness of the exhaust manifold assembly over a larger range of operating temperatures.
    Type: Grant

  • EXHAUST PLENUM CHAMBER CONSTRUCTIONS INCLUDING THERMAL BARRIER COATINGS FOR OPPOSED-PISTON ENGINES
    Publication number: 20200182114
    Abstract: An exhaust plenum chamber with a thermal barrier coating for an opposed-piston engine reduces heat rejection to coolant, while increasing exhaust temperatures, fuel efficiency, and quicker exhaust after-treatment light-off. The exhaust plenum chamber can include a coating on the inside surface of the chamber. Posts which are structural and provide cooling channels or passageways can be present in the exhaust plenum chamber and coated with the thermal barrier coating material.

  • ROBUST SUPERCHARGER FOR OPPOSED-PISTON ENGINES EQUIPPED WITH EXHAUST GAS RECIRCULATION
    Publication number: 20200158131
    Abstract: A supercharger assembly includes rotors, a base plate, and a housing with an anti-fouling material on one or more surfaces where accumulation of soot and/or soot-like material may lead to mechanical friction and possibly seizing. The anti-fouling material can have oleophobic and/or hydrophobic properties.
