  • Patent number: 10316738
    Abstract: A turbocharger engine includes an engine body and a turbocharger. The turbocharger includes a large turbo unit having a large turbine chamber, a large compressor chamber, and a large turbine shaft extending between the two chambers; and a small turbo unit having a small turbine chamber, a small compressor chamber, and a small turbine shaft extending between the two chambers. The large compressor chamber is disposed upstream of the small compressor chamber in an intake passage. A large turbo axis and a small turbo axis are disposed to extend generally in the same direction as an engine output axis. The large turbo unit is disposed such that the large turbo axis is non-parallel to the engine output axis, and a large-compressor-chamber-side portion of the large turbo axis is closer to the engine output axis than a large-turbine-chamber-side portion thereof in a plan view in an axis direction of the cylinder.

  • Patent number: 10309281
    Abstract: A system for reducing environmentally harmful emissions from an internal combustion engine. The system may incorporate an exhaust after-treatment device. The exhaust after-treatment device may use selective catalytic reduction to remove certain emissions from the exhaust of the engine. Urea solution may be inserted into the exhaust emissions, which is decomposed to ammonia to become a reduction agent for reduction of NOx in the emissions. The engine may be managed by a controller and the exhaust after-treatment device may be managed by another controller. These controllers may be cascaded, or be managed by a third controller that provides hierarchical or coordinated control of engine performance and emissions reduction. The engine and the exhaust after-treatment device may be modeled to aid in designing and building a system for coordinated control of an actual engine and a selective catalytic reduction after-treatment device. The controllers may be predictive model controllers.
