A cylinder head assembly for an internal combustion engine includes a cast cylinder head and a turbocharger housing integrally cast with the cylinder head and having an integrally cast wastegate housing. The turbocharger housing is configured to receive a turbocharger cartridge rotatably supporting a shaft coupled between a compressor wheel and a turbine wheel. The integrally cast wastegate housing defines a wastegate chamber configured to receive a wastegate valve, a flow of exhaust gas from the turbine wheel, and a flow of wastegate exhaust gas.

An agricultural harvester includes an IC engine, a grain tank, and a fluid cooling system for at least one component onboard the agricultural harvester. The fluid cooling system has a cooling package positioned between the IC engine and the grain tank. The cooling package includes a housing, and a plurality of cooling units arranged in a side-to-side manner within the housing, transverse to a fore-aft direction of the harvester.

The invention concerns a seal (5) for sealing off the gap between a heat exchanger (1) and the inside wall of a groove (7) in a fluid channel for accommodating said heat exchanger [1], the seal (5) comprising at least one fixing member (51, 52) for fixing the seal (5) on at least part of the circumference of the heat exchanger (1) and at least a first (53) and second lip (54) adapted to contact opposite sides (71, 72) of the groove (7) to thereby seal off the gap between the heat exchanger (1) and the fluid channel and to fix said at least part of the circumference of the heat exchanger (1) inside the groove (7).

An intake system of an engine mounted on a vehicle where a cabin is air-conditioned by an air conditioner, is provided. A heat exchanger of an evaporator of the air conditioner is divided into a first heat exchanger and a second heat exchanger that are mutually independent, and an air passage includes a first division passage and a second division passage. The intake system cools intake air utilizing a part of the air conditioner, and includes a connecting passage that guides first air cooled by passing through the first heat exchanger, a passage switch, and a controller. When the controller determines that a cooling demand for the intake air exists, it controls the first air to flow into an intake passage through the connecting passage, and when the controller determines that there is no cooling demand, it controls the first air to flow into the first division passage.

The intake air cooling device 100A constitutes a heat exchange device that performs heat exchange of the intake air of the internal combustion engine 6. The intake air cooling device 100A includes the heat exchange part 1A configured to perform heat exchange between the cooling liquid W that is introduced thereto and the intake air that is passing therethrough, and the intake air control valve 2 configured to perform control of the intake air that passes through the heat exchange part 1A. The cooling liquid introduction port 13 of the heat exchange part 1A and the intake air control valve 2 are provided at positions opposing each other with respect to the heat exchange part 1A.

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.

A vehicle has a hybrid drive including an internal combustion engine and at least one electric motor. The hybrid drive has a charging device for generating an air flow. A charge air path guides the air flow from the charging device to the internal combustion engine. A charge air cooler is arranged in the charge air path between the charging device and the internal combustion engine. The hybrid drive has an electric battery for supplying electric power to the at least one electric motor. The effort involved in cooling the battery is reduced if the battery is incorporated into the charge air path between the charge air cooler and the internal combustion engine in such a way that the air flow can flow through and/or around it.

A system and method for removing condensate water of an intercooler for a hybrid vehicle are configured to improve combustion efficiency of an engine by supercharging intake air to a combustion chamber of the engine using an electronic compressor instead of an existing turbocharger and configured to backward drive the electronic compressor to distribute and capture the condensate water generated in the intercooler, especially, when the engine is turned off.

An intake device for an internal combustion engine includes: a main pipe having an upstream end forming a suction port and a downstream end configured to be connected to an intake port of an internal combustion engine main body; a compressor of a supercharger provided in the main pipe; an intercooler provided in the main pipe at a position downstream of the compressor and including a cooling part, an upstream header provided upstream of the cooling part, and a downstream header provided downstream of the cooling part; a throttle valve disposed in the main pipe at a position downstream of the intercooler; a bypass pipe having a first end and a second end, the bypass pipe being connected to a part of the main pipe between the cooling part and the throttle valve; and a catch tank provided in the bypass pipe and configure to catch condensed water.

A power system for a work vehicle includes an alcohol tank configured to store alcohol; a catalytic converter fluidly coupled to receive alcohol from the alcohol tank and configured to convert the alcohol into ether; and an engine including one or more piston-cylinder sets configured to selectively receive the alcohol stored in the alcohol tank and the ether converted by the catalytic converter and to combust the alcohol and the ether with air to produce mechanical power and exhaust gas.
