  • Patent number: 10711740
    Abstract: A system for feeding air to an engine of a vehicle includes a heat exchanger arranged along a duct for feeding air, downstream of a supercharging compressor, to cool a flow of air fed by the air compressor, by a fluid that circulates in an engine cooling circuit. The system also includes an evaporator, interposed in the duct downstream of the heat exchanger, to further cool the air flow by a coolant that circulates in an air conditioning circuit of the vehicle. The air conditioning circuit includes a coolant compressor and a controller for controlling activation of the coolant compressor, depending on a request for air conditioning of a passenger compartment of the vehicle, and a request for cooling the air fed to the engine. The electronic controller is configured to enable the coolant compressor to be activated only when the engine load is below a certain threshold.

  • Patent number: 10408122
    Abstract: Synergistic induction and turbocharging includes the use of one or more throttles in close proximity to each cylinder intake valve to control air flow in each intake port delivering air to combustion cylinders in an internal combustion engine system. A turbocharger may also be affixed in close proximity to each cylinder exhaust valve to enable a synergistic combination of hyper-filling cylinders with combustion air and immediate harvesting of exhaust gas by adjacent turbochargers. In some implementations the turbochargers may be low-inertia turbochargers. The combination of individual throttles per intake port and a turbocharger in close proximity to each cylinder enables faster ramp-up of an engine in the early stages of acceleration. Various implementations thus provide improved fuel economy and improved engine performance in tandem, instead of one at the expense of the other.

    Abstract: An induction system for a supercharged internal V-type combustion engine includes a monolithic continuous unitary casting housing a supercharger with a rotor and gear assembly operative to discharge pressurized air to a common bounding receiving plenum, through a first slidably-removable intercooler providing a first cooling, and then to a pair of second side intercoolers providing a second cooling within the bounded plenum and in fluid communication therewith. First and second intercoolers are secured within the monolithic housing. The monolithic housing provides a robust and stable housing of light weight and allows an exterior air cooling as well. Side walls of the supercharger are separate from and are spaced from air intake runners of a cylinder block. Air in the plenum is additionally cooled by convective surface cooling while being guided in an appropriate direction.

  • Patent number: 9657659
    Abstract: Methods and systems are provided for controlling air ingestion in an engine during idle conditions. One example approach includes adjusting an opening of a common shut-off valve via an electronic controller, the common shut-off valve regulating each of motive flow through an aspirator and crankcase ventilation (CV) flow from a crankcase. As such, the common shut-off valve may be closed by the electronic controller during engine idle to cease each of the motive flow through the aspirator and the CV flow from the crankcase.

  • Patent number: 9551273
    Abstract: A charge air cooler includes a high temperature side heat exchanger and a low temperature side heat exchanger. The high temperature side heat exchanger is provided on a high temperature side cooling flow path through which a first refrigerant cooled by a first heat exchanger (radiator) flows. The low temperature side heat exchanger is provided on a low temperature side cooling flow path through which a second refrigerant cooled cooler than the first refrigerant by a second heat exchanger (sub-radiator) flows. The low temperature side heat exchanger cools, by the second refrigerant, intake air cooled by the high temperature side heat exchanger. According to the above charge air cooler, the second heat exchanger (sub-radiator) can be prevented from becoming big in size, and intake air temperature can be cooled to desired temperature.

  • Patent number: 9551275
    Abstract: A cooling system is provided for an engine. The cooling system may have an air cooler configured to cool intake air being supplied to the engine. The cooling system may also have a sensor configured to generate a temperature signal indicative of a temperature of the intake air and a fan in proximity to the air cooler. The cooling system may further have a controller in communication with the sensor and the fan. The controller may be configured to cause the fan to operate at a speed that is a function of the temperature signal when the temperature of the intake air is above a threshold temperature. The controller may further be configured to selectively cause the fan to pulse when the temperature of the intake air drops below the threshold temperature.

  • Patent number: 9482146
    Abstract: A system, apparatus and method for maintaining power in an internal combustion typically turbocharged aircraft engine is disclosed. During descent, air pressure and temperature in the manifold can fall to dangerous levels. This is because engine power is low and likewise turbocharger output is also low. The system and method provide for a bypass of the heat radiator during low power periods, or with low ambient temperature or both. A parameter is measured, often manifold pressure or temperature and the degree of bypass is adjusted commensurately.

  • Patent number: 9441578
    Abstract: A manifold distributes gases into intake ducts of a motor vehicle combustion engine. The intake ducts are distributed in at least two distant groups, each duct of one group supplying one and the same cylinder of the engine as a duct of the other group. The manifold includes a manifold casing through which a flow of intake gases can flow, and an injection duct for injecting a flow of recirculated exhaust gases into the flow of intake gases. The casing is capable of directing the flow of intake gases and the flow of recirculated exhaust gases toward the intake ducts of the engine, and the injection duct is arranged inside the manifold casing so as to be able to be positioned between the two groups of intake ducts.

The engine block may include a cylinder head disposed on an upper side of the engine block, an intake manifold disposed at one side of the cylinder head, and an exhaust manifold disposed at the other side of the cylinder head. The turbocharger may compress intake air by exhaust gas exhausted from the exhaust manifold, and the intake line may be formed from the turbocharger to the intake manifold to transfer the intake air compressed by the turbocharger to the intake manifold. The intercooler may be disposed on the intake line adjacent to the intake manifold to cool the compressed intake air. The compressed intake air discharged from the turbocharger may pass a side of the cylinder head and an engine coolant flowing the cylinder head may cool the compressed intake air.
