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.

A supercharger intercooler includes three sequential Anti-Reversion Plenums (ARPs) separated by heat exchangers, in right and left air paths between the supercharger and intake ports. The intercooler resides above and beside the supercharger and has paths for each bank of a V8 engine. An air flow from the supercharger is up and into a first ARP, is split into right and left flows into right and left first heat exchangers, passes into second ARPs and turns down, flows though right and left second heat exchangers into third ARPs and then into the engine. Reversion pulses from the engine are reduced by each ARP, increasing air flow into the engine, and reducing pulsations in the air flow, thereby increasing power, improving fuel economy, throttle response, driveability, and reducing emissions.

A dual, dual-pass intercooler assembly for an intercooler supercharger system comprising an intercooler lid mountable to a supercharger housing; a pair of intercooler cores coupled mountable to and within at least one of the intercooler lid and the supercharger housing; wherein the pair of intercooler cores configured to receive and cool supercharger air upon a first pass through the pair of intercooler cores and receive and further cool the supercharger air upon a second pass through the pair of intercooler cores prior to receipt by an engine.

A heat exchanger system includes a radiator and a charge air cooler. The charge air cooler includes two interconnected cores, being a first core mounted next to the radiator and a second core mounted upstream of the radiator so that air output from the first core does not pass through the radiator.

A hydrogen fueled powerplant including an internal combustion engine that drives a motor-generator, and has a two-stage turbocharger, for an aircraft. A control system controls the operation of the motor-generator to maintain the engine at a speed selected based on controlling the engine equivalence ratio. The control system controls an afterburner, an intercooler and an aftercooler to maximize powerplant efficiency. The afterburner also adds power to the turbochargers during high-altitude restarts. The turbochargers also include motor-generators that extract excess power from the exhaust.

A method of operating a two-stroke cycle, opposed-piston engine comprising a pumping device coupled to pump air to cylinders of the engine through a charge air cooler and an aftertreatment system of thermally-activated devices coupled to receive exhaust from the cylinders by which a thermal state of the exhaust sufficient to sustain thermal activation of one or more of the aftertreatment system devices may be maintained during a deceleration or motoring condition of operation by reducing the mass airflow to the engine.

An air cooling device includes a first inlet surge tank, a first heat exchanger to cool air introduced from the first surge tank, a second inlet surge tank, a second heat exchanger to cool air introduced from the second surge tank, and an outlet surge tank. The outlet surge tank receives both of airs introduced from the first heat exchanger and the second heat exchanger and the airs flows from the outlet surge tank toward an internal combustion engine. The outlet surge tank includes a merging space and a fixing hole. The merging space is where the airs introduced from the first heat exchanger and the second heat exchanger merge with each other. A fastening member to fasten the outlet surge tank passes through the fixing hole from an outer surface of the outlet surge tank away from the merging space toward the internal combustion engine.

A spark-ignited gas engine system comprises a combustion chamber defined by a piston, a head with a spark plug mechanism, and a cylinder having an associated intake valve and an associated exhaust valve, into which a mixture of combustible gas and air is entered via an intake manifold of the engine to drive a crankshaft. The system further comprises at least one turbocharger to compress the mixture. The system further comprises at least one camshaft, driven by the crankshaft via a gear assembly connected to the crankshaft, that comprises at least one cam that actuates the intake valve and the exhaust valve, at least one camphaser, coupled to the crankshaft via the gear assembly, and a controller to adjust a cam angle operation of the intake valve and the exhaust valve by adjusting the camphaser to a desired phase position to meet a target rotational phase of the camshaft.

A dual, dual-pass intercooler assembly for an intercooler supercharger system comprising an intercooler lid mountable to a supercharger housing; a pair of intercooler cores coupled mountable to and within at least one of the intercooler lid and the supercharger housing; wherein the pair of intercooler cores configured to receive and cool supercharger air upon a first pass through the pair of intercooler cores and receive and further cool the supercharger air upon a second pass through the pair of intercooler cores prior to receipt by an engine.

A system for heating a cabin of a vehicle can include: a liquid-cooled charge air cooler configured to receive a liquid, to receive heated air from one of a turbocharger and a supercharger of the vehicle, to cool the heated air via the liquid, thereby heating the liquid, to output the cooled air to an intake manifold of an engine of the vehicle, and to output the heated liquid; and a multi-function heat exchanger connected to the liquid-cooled charge air cooler, the multi-function heat exchanger configured to receive the heated liquid outputted by the liquid-cooled charge air cooler, to generate heated air via the heated liquid, and to output the heated air into the cabin of the vehicle, thereby heating the cabin of the vehicle.
