A method of operating a forced induction gaseous-fueled engine includes mixing gaseous-fuel and engine intake air to form a mixture at a fuel mixer. The method includes delivering the mixture to an intake manifold by at least partially bypassing a charge air cooler.

An air filter device for a motor vehicle is provided with a filter housing having an air inlet and an air outlet, a filter insert which is received in the filter housing and divides the inside of the filter housing into an untreated air section and a pure air section, and a bypass line for supplying air into the untreated air section. The bypass line extends from a connection opening in the filter housing to a cooler, especially a charge air cooler of the motor vehicle.

Methods and systems for an engine intake system. In one example, a system comprises a first charge air cooler arranged upstream of a second charge air cooler. The first charge air cooler is configured to provide thermal transfer between a compressed charge air and a fresh intake air.

An air cooling system for a vehicle engine includes an air intake configured to receive intake air for delivery to the engine, a first coolant loop thermally coupled to the air intake to provide cooling to the intake air, and a second coolant loop thermally coupled to the air intake to provide further cooling to the intake air. The first and second coolant loops are separate loops using a common condenser

A heat exchanger for providing charged air to a vehicle is described. The heat exchanger includes a plurality of heat exchange elements, and at least one passage. The plurality of heat exchange elements is stacked together in between a pair of side plates, and ends of the plurality of heat exchange elements are received in a pair of headers to configure a fluid circuit. The at least one passage is formed in a first heat exchange element amongst the plurality of heat exchange elements, along with the plurality of heat exchange elements and the first heat exchange element is formed above at least few heat exchange elements of the plurality of heat exchange elements.

A cooling air feeding apparatus is for a motor vehicle, which has a motor vehicle body and a drive train, the drive train being assigned a cooler, and at least the cooler being arranged in a rear region of the motor vehicle body. The cooling air feeding apparatus has a throughflow opening, which is in the rear region and which is configured to receive air from surroundings of the motor vehicle and to feed the received air to the cooler. In order to regulate a driving state of the motor vehicle, the throughflow opening is configured with a variable throughflow cross section with the aid of a closing element, which is assigned to the cooling air feeding apparatus. The throughflow opening is configured to be controllably closed individually completely or partially and to be opened completely.

An intake system assembly including an intake manifold including a housing defining an interior conduit in fluidic communication with an intake valve and a lattice structure extending from an outer surface of the housing. The lattice structure includes a plurality of intersecting walls and the lattice structure and the housing form a continuous piece of material.

A fan arrangement for a cooling module in a vehicle. The vehicle (6) has a radiator fan (10) providing an air flow through a flow passage (5) and the cooling module in an intended flow direction. The cooling module includes a radiator (3) and at least one further cooler (1, 2) arranged in an upstream position of the radiator (3) with respect to the intended flow direction through the flow passage (5). The fan arrangement includes at least one additional electrically driven fan (4). The additional electrically driven fan (4) is arranged in the flow passage (5) in a position downstream of the radiator (3) and upstream of the radiator fan (10) with respect to the intended flow direction through the flow passage (5). The electrically driven fan (4) is configured to provide an air flow through a restricted portion (18) of the flow passage (5) and the cooling module during certain occasions when the operating conditions include the radiator fan not being in operation.

An inlet tank for a charge cooler comprises a manifold portion, a turbocharger inlet port, and a supercharger inlet port. The turbocharger inlet port is in fluid communication with a compressor wheel of a turbocharger and the manifold portion of the inlet tank. An opening is formed in a sidewall of the turbocharger inlet port. The supercharger inlet port is in fluid communication with an electric supercharger and intersects the turbocharger inlet port. The opening formed in the sidewall of the turbocharger inlet port provides fluid communication between the supercharger inlet port and the turbocharger inlet port. A valve element selectively determines when a flow of air from the supercharger inlet port enters the turbocharger inlet port through the opening based on a pressure differential present between the air exiting the compressor wheel of the turbocharger and the air exiting a compression mechanism of the electric supercharger.

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.
