Abstract: In the present invention, a package is partitioned into upper and lower sections. An engine and a generator are both disposed in the lower section. In the upper section are disposed: a radiator chamber in which a radiator and a radiator fan are disposed, and an intake chamber in which an intake silencer is disposed. A ventilation hole directly communicates the radiator chamber with an engine chamber in which the engine and the generator are disposed. The ventilation hole is displaced from the radiator fan in a long-side direction of the package. A ventilation hood covers above and around the ventilation hole. An outlet opening of the ventilation hood is formed being displaced in a short-side direction (Y) of the package to face the ventilation hole.

Abstract: In a package-storage type engine generator, a package (2) is partitioned into an upper section and a lower section. An engine (11) and a generator (12) are disposed in the lower section, and a radiator (42) and a radiator fan (43) are disposed in the upper section. An upper/lower partition member (32) partitions the package (2) into the upper section and the lower section. A portion of the upper/lower partition member (32), which faces the radiator fan (43), is formed in a downward inclined shape from a center portion to an outer edge portion of the package.

Abstract: An engine coolant circuit circulating coolant to cool an engine includes: a plurality of thermostatic switching valves disposed in parallel in passages leading from a coolant outlet of the engine; electrically driven three-way valves disposed downstream from the respective thermostatic switching valves in terms of a circulating direction of the coolant; and a radiator and an engine waste heat recovery device disposed in parallel in passages leading from coolant outlets of the electrically driven three-way valves, each one of the electrically driven three-way valves being provided with two coolant outlets, having one of the two coolant outlets thereof configured to communicate with the radiator, and having another one of the two coolant outlets thereof configured to communicate with the engine waste heat recovery device.

In the upper section are disposed: a radiator chamber in which a radiator and a radiator fan are disposed, and an intake chamber in which an intake silencer is disposed. A ventilation hole directly communicates the radiator chamber with an engine chamber in which the engine and the generator are disposed. The ventilation hole is displaced from the radiator fan in a long-side direction (X) of the package. A ventilation hood covers above and around the ventilation hole. An outlet opening of the ventilation food is formed being displaced in a short-side direction (Y) of the package to face the ventilation hole.

Abstract: A package-storage type engine generator includes a package partitioned into an upper section and a lower section, an engine and a generator both disposed in the lower section, and a radiator and a radiator fan both disposed in the upper section. The radiator is horizontally disposed so that heat-transfer surfaces of the radiator are horizontal, and the radiator fan is disposed above the radiator. Vent holes are formed in an outer plate of the upper section so as to be located lower than a position of the radiator.
