摘要:
The invention provides an engine cooling device capable of suitably promoting the warm-up of an engine. This device comprises a cooling circuit and a heat-accumulating passage. The cooling circuit is composed of a radiator passage, a bypass passage, and a flow rate control valve 22 for controlling the flow rate of coolant flowing through the bypass passage. The heat-accumulating passage is provided with a heat-accumulating container 16, and constitutes a heat-accumulating circuit for causing coolant in the heat-accumulating container 16 to circulate via an engine E. The cooling device completes the heat-accumulating circuit by connecting the heat-accumulating passage to the cooling circuit to supply the cooling medium in the heat-accumulating container 16 to the body of the engine E, opens the flow rate control valve 22 to increase a flow rate of cooling medium flowing through the bypass passage, then disconnects the heat-accumulating passage from the cooling circuit, and closes the flow rate control valve 22.

An internal combustion engine (1) includes a circulation system (C) which circulates a heat medium, a cylinder head part channel (23a) which circulates the heat medium into a cylinder head (1a), a cylinder block part channel (23b) which circulates the heat medium into a cylinder block (1b), a connecting channel (23c) which connects the cylinder head part channel (23a) with the cylinder block part channel (23b), heat supply means (23) that supply heat accumulated in the regenerator (10) to the internal combustion engine (1), and restraining means (38) that restrain heat circulation in the connecting channel (23c) when heat is supplied by the heat supply means (23) or the internal combustion engine (1) is under cold conditions.
摘要:
An electronic control unit (ECU) (30) of an engine system (100) starts a control (preheat) for supplying heat reserving hot water stored in a heat accumulating device (21) to an engine (10) prior to an engine start. The ECU (30) determines a time for continuing the preheat on the basis of a cooling water temperature of the engine (10) so as to execute the engine start after a warming-up of the engine (10) is reliably finished. Further, during the execution of the preheat, a lighting lamp (28) is turned on, and that incidence is recognized to a driver. When the preheat is completed, the ECU (30) automatically starts the engine (10).
摘要:
An engine cooling apparatus includes a block water jacket (3) formed in a cylinder block (2). The block water jacket (3) includes a coolant inlet (5) through which coolant is introduced into the block water jacket (3). In a cylinder head, a head water jacket (7) is formed. A water jacket spacer is fitted into the block water jacket (3). A flow-directing plate (9) is formed integrally with the block water spacer. Immediately after the flow-directing plate (9) directs the coolant toward the head water jacket (7), the coolant flows into the head water jacket (7). Then, the coolant is circulated in the head water jacket (7) until warming-up is completed. After the warming-up is completed, the coolant flows into the block water jacket (3) from the head water jacket (7) to cool the cylinder block (2).

摘要:
A mounting structure for a heat accumulation tank is provided which is capable of reliably holding the heat accumulation tank 1, achieving even surface pressure, and eliminating the possibility of a slow leak. The mounting structure includes an elastic member 39 that wraps around a tank main body 10; and a heat accumulation tank 1 mounting member 30 which wraps around an outer peripheral surface of the elastic member and holds the tank main body 10 by being tightened in the circumferential direction, and which attaches to a receiving member. The elastic member 39 is a molded part. The length of the elastic member 39 is shorter than the length of the circumference of the outer peripheral surface of the tank main body.
