    摘要: An additive supply device for an engine, the additive supply device includes an additive supply system, a heater, an intake air temperature sensor and a heating control unit. The additive supply system is positioned outside of an engine compartment, and the additive supply system includes a tank, a pump, a supply passage. The heater heats the additive inside the additive supply system. The heating control unit is configured to (i) actuate the heater when a detected intake air temperature is low, and stop the actuation of the heater when the detected intake air temperature rises, and (ii) continue the actuation of the heater when a condition under which the detected intake air temperature and the temperature of the additive inside the additive supply system have deviated from each other is fulfilled during the actuation of the heater.

    摘要: A heat insulator includes a first covering part (21b) and a second covering part (21a, 21c). The first covering part (21b) is configured to cover a bent part (12) formed in an exhaust pipe of an internal combustion engine. The first covering part (21b) has a plurality of slits (41, 42) extending in a circumferential direction of the exhaust pipe. The plurality of slits (41, 42) are arranged with a given space from each other in a direction in which the exhaust pipe extends such that a plate part between slits (43) is present between the plurality of slits (41, 42). The second covering part (21a, 21c) covers the other part of the exhaust pipe than the bent part (12). At least a part of the second covering part (21a, 21c) is bonded to the exhaust pipe.

    摘要: An additive supply device includes: an addition valve (2) that injects urea water into an exhaust passage (1) of an internal combustion engine; a pipe (4); and a pump (6), a tank (5) and a pipe (4). The connector (3) is provided so that an inner upper end of the connector (3) is located at a position higher than the position of the connection port (2a) when the addition valve (2) is connected to the connector (3). A pressure accumulation portion (10) in which compressed air that, when the pumping of the urea water by the pump (6) is stopped, expands to a volume equal to or larger than the volume upon freezing and expansion of the urea water remaining inside the addition valve (2) and the pipe (4) is accumulated is provided in an upper part inside the connector (3), at a position higher than the position of the connection port (2a).

    摘要: A aqueous urea solution supply device (200) for an engine (1) is provided with a tank (210) that stores aqueous urea solution, a valve (230) configured to add the aqueous urea solution to exhaust gas, and a passage (240) configured to supply the aqueous urea solution from the tank (210) to the valve (230). When a pressure of the aqueous urea solution supplied to the valve (230) is equal to or lower than a predetermined pressure and the amount of the aqueous urea solution in the tank (210) is equal to or smaller than a predetermined threshold, an electronic control unit (80) determines that the aqueous urea solution in an amount required for cooling of the valve (230) cannot be supplied from the tank (210) to the valve (230) and executes a return control for returning the aqueous urea solution from the valve (230) to the tank (210).
