Abstract:
An engine working machine (1) formed by storing a radiator (5) and a cooling fan (6) for leading heat exchange air for the radiator (5) in a package (2) together with an engine (3) and a working machine (4), wherein a storing space (E2) for the engine (3) and working machine (4) excluding a ventilating hole (13) communicating to a space (15) between the radiator (5) and the cooling fan (6) is shielded by partitions (9) from an air leading space (E1) to which air is led after being passed through the radiator (5) by the cooling fan (6), and a cooling air leading port (12) for externally cooling the engine (3) and the working machine (4) is formed in a part of the package (2) so that outside air led from the cooling air leading port (12) passes the storing space (E2) for the engine (3) and the working machine (4) and is exhausted from a ventilating port (13) to the air leading space (E1) to which air is led after having passed through the radiator (5).
Abstract:
A dual use of a heater core that enables heating the cabin, cooling the engine or both on demand regardless of the passenger's cabin heating and cooling requirements. This use of the heater core is enabled by a HVAC airbox system with a cooling door that can be selectively positioned such that at least some of the air moving through the heater core is directed outside of the HVAC system and outside of the passenger cabin to the underhood area of a vehicle, thereby providing supplemental engine cooling on demand regardless of the passenger's cabin heating and cooling requirements. The cooling door can be positioned automatically dependent on any parameter, or combination of parameters, of the engine such as engine coolant temperature or engine oil temperature. The blower speed and the position of the cooling door are adjusted depending on the whether and how much supplemental engine cooling is required.
Abstract:
The present invention relates to a heat dissipation system for large generator sets by a remotely installed radiator. The present invention applies to a heat dissipation and ventilation system for a plant room having large chillers and generator sets. Further, the invention relates to heat dissipation and ventilation system for a large plant room configurable with remotely placed radiator, wherein the said system is adapted to exhale the heated air towards proximity of the distant exhaust shaft for efficient heat dissipation. Remotely placed radiators are without their conventional ventilation fans. However heat dissipation in the radiator and hence ventilation required for the same is addressed by a separate set of centrifugal blowers. The configuration, capacity and the layout of the blowers in the plant room enable it to ventilate the air cooled chillers installed in the same plant room.
Abstract:
The invention relates to a hybrid drive device comprising a combustion engine (20), an electric motor (5), both arranged for driving a drive axle (10), an electric generator (4), a closed chamber (10 in heat receiving contact with and surrounding the combustion engine (20), and a piston unit (3) arranged for driving the generator (4). The chamber (1) has an inlet (11) for receiving a fluid and an outlet (12) connected to the piston unit (3) for driving a piston of the piston unit (3), such that in operation fluid inside the chamber (1) is pressurized by heat transferred from the combustion engine (20) to the chamber (1) and the pressurized fluid is operating the piston unit (3). The hybrid device may be used in a hybrid vehicle. An independent claim is included for a hybrid vehicle operated by a hybrid motor management system based on a geographic position determining system.
Abstract:
The invention relates to an arrangement for controlling the temperature of air being fed to a vehicle engine (17). The arrangement comprises an engine compartment (15) in which said engine (17) is arranged. The engine compartment (15) is provided with an ambient air intake (16) allowing an airflow into said engine compartment (15). The engine is provided with an engine air intake (18) arranged inside the engine compartment (15). The arrangement further comprises an air fan (19) for forcing the airflow via the ambient air intake (16) into the inside of the engine compartment (15). The engine air intake (15) is arranged in a position allowing at least a substantial part of said airflow to enter the engine air intake (15).
