A construction machine is capable of reducing a decrease in work efficiency due to maintenance for capturing dust. The construction machine includes: an engine; a heat exchanger; a cooling fan that sucks air into an engine chamber to pass the air through the heat exchanger; an intake chamber independent of the engine chamber; an intake tube connected to the intake chamber; and a dust receiving part. The intake tube has a curved part, which has an outside inner wall surface allowing dust in the air to contact it. The dust receiving part is located downstream of the outside inner wall surface to be capable of receiving dust.

A thermal management system for a vehicle may include a refrigerant circuit in which a refrigerant circulates, as well as a heating circuit, a first coolant circuit configured for a temperature control of a drive device of the vehicle, and a second coolant circuit configured for a temperature control of an electrical store of the vehicle in which a coolant circulates. The system may further include a chiller incorporated in the refrigerant circuit and a chiller guide fluidically separate from the refrigerant circuit. The chiller guide may have a chiller path configured to conduct the coolant and which extends through the chiller, and may have a bypass path configured to conduct the coolant and which circumvents the chiller. The system may additionally include a chiller valve device configured to selectively fluidically connect the first coolant circuit and the second coolant circuit to the chiller path and the bypass path.

A containerised generator set comprises a generator arranged within a container having a first aperture through which cooling air is exhausted in use. A pair of first doors are arranged to pivot outwardly on either side of the first aperture, with a removable wall being removably mounted between the first doors and spaced apart from the body of the container by the first doors from its lower end region to its upper end region in its mounted position. The removable wall and the first doors define an exhaust air duct which preferably includes a sound absorbent material. The exhaust air duct extends for at least most of a total height of the body of the container to attenuate noise from the generator. Exhausted cooling air flows upwardly from the open upper end of the exhaust air duct and away from the immediate operating environment.

a vehicle cooling air introduction structure includes: an outer plate member that covers a front side, relative to a vehicle body, of a radiator; a cover member that is provided adjacent to an upper side, relative to the vehicle body, of the outer plate member and covers a front upper side, relative to the vehicle body, of the radiator; and an opening member that is moved in a rearward direction, relative to the vehicle body, by wind pressure during travel to thereby open an open portion at a lower end portion of the cover member.

An alternator adapter for a generator engine includes a main body defining an airflow chamber. The main body includes an airflow outlet in a first end of the main body, an engine shaft opening in a second end of the main body opposite the first end, and an airflow inlet between the first end and the second end. The alternator adaptor also includes an engine mount coupled to the first end of the main body around the airflow outlet and aligned with the engine shaft opening, and an alternator mount coupled to the second end of the main body around the engine shaft opening.

An engine assembly including an internal combustion engine configured to be received in an engine compartment and a heat exchanger having a first conduit fluidly connected to a fluid circuitry of the engine and a second conduit fluidly connecting an interior of the engine compartment to its environment. The first conduit is in heat exchange relationship with the second conduit. The assembly further includes a forced air system operable in use to provide an air flow from the environment to the outlet via the second conduit of the heat exchanger and the engine compartment. The assembly further includes a selector valve configurable to selectively fluidly connect an air intake of the internal combustion engine with the interior of the engine compartment in a first valve position and with the environment in a second valve position. A method for supplying air to an internal combustion engine is also discussed.
