Abstract:
A thermal choke, includes (1) a body, comprising a heat conductive material, (2) an electric heater, on or in the body, (3) a temperature sensor, on or in the body, and (4) a fin, in a channel surrounded by the body. The thermal choke is configured to fit between a throttle assembly and a cylinder of a spark ignition engine.
Abstract:
A wheel loader (100) is provided with an engine compartment (2), a cooling compartment (3), a partition wall (6), a top plate (81), and a first duct body part (7). The top plate (81) can be removed and defines an upper surface of the engine compartment (2). A first end part (71) of the first duct body part (7) is positioned inside the engine compartment (2). A second end part (72) of the first duct body part (7) is positioned inside the cooling compartment (3). The first duct body part (7) is attached to the top plate (81).
Abstract:
A ventilation structure of an engine compartment (4) that houses an engine and is adjacent to a cooling fan that supplies cooling air to a heat exchanger in a form of a radiator (51) is provided. A ventilation structure of the engine compartment (4) includes: an exterior cover (3) with which the engine and the cooling fan are covered; and a ventilation duct (8) that includes an inner surface of the exterior cover (3), in which a first end of the ventilation duct (8) is open in the engine compartment (4) while a second end of the ventilation duct (8) intercommunicates with a surrounding area of the cooling fan.
Abstract:
A wheel loader (100) is provided with a top plate (81), a plate-like member (17), a diesel particulate filtering device (121), and a first duct (18). The top plate (81) has a first outdoor air intake port (84). The plate-like member (17) is disposed below the first outdoor air intake port (84). The diesel particulate filtering device (121) is disposed below the plate-like member (17) . A first end part (181) of the first duct (18) is positioned to the rear of the diesel particulate filtering device (121). A second end part (182) of the first duct (18) is positioned inside the cooling compartment (3). A connector (1211) is disposed in an air flow generated between a gap (33) and the first end part (181).
