Abstract: In an exhaust heat recovery structure (10), a heat exchange portion (30) (a tubular part (32)) is configured such that a height of a lower inner surface (322) is lowered from an inlet (32A) toward an outlet (32B). Hence, when exhaust gas is condensed and condensed water is thereby generated inside the heat exchange portion (30) (the tubular part (32)), the condensed water flows from the inlet (32A) side toward the outlet (32B) side where the lower inner surface (322) is lowered, and is then discharged to a piping part (20). Accordingly, the condensed water is unlikely to be collected inside the heat exchange portion (30).

Abstract: In a distribution flow path that allows engine coolant to circulate between an exhaust heat recovery unit and an engine, an upstream flow path on the upstream side of the engine and a downstream flow path on the downstream side of the engine are communicated with each other by means of a bypass flow path to thereby form a short flow path with a shorter flow path length than in a case where the engine coolant that has exited the exhaust heat recovery unit passes through the engine. A valve that can adjust the amount of the engine coolant flowing to the bypass flow path and a short flow path pump are disposed.

Abstract: There is provided an engine control device including (1) a regulator that regulates a flow rate per unit of time of exhaust gas discharged from an engine, and (2) a controller that, when an external temperature detection section detects an external temperature below freezing point, and a previous engine operation duration is shorter than a predetermined first duration, controls the regulator such that the flow rate rises to exceed a predetermined normal state, until a predetermined second duration has elapsed since the engine was started up.

Abstract: To obtain a catalytic converter device that can suppress a drop in the effect of heating a catalyst carrier caused by water droplets produced in an exhaust pipe. A holding mat (26) that holds a catalyst carrier (14) in a case cylinder (28) is given a three-layer structure comprising an inside fiber layer (30), a solid layer (32), and an outside fiber layer (34). The solid layer (32) projects toward an upstream side from an upstream-side end face (14A) of the catalyst carrier (14), and an interstice portion (40) is configured between the projecting portion (38) and the case cylinder (28). Water droplets adhering to the inner peripheral surface of the case cylinder (28) do not reach the catalyst carrier (14) because the projecting portion (38) serves as a barrier.

Abstract: There is provided an exhaust heat recovery structure that may suppress boiling of coolant in a heat exchanger. The exhaust heat recovery structure includes a first pipe (12), a second pipe (18), a valve (16) and a thermostat (22). Exhaust gas from an engine flows in the first pipe. The second pipe branches from the first pipe and a heat exchanger (20) that exchanges heat between the coolant and exhaust gas is provided at the second pipe. The valve is provided at the first pipe or the second pipe. The valve adjusts a flow amount of exhaust gas flowing into the second pipe by opening and closing. The thermostat (22) is equipped with a heat-sensing portion that is disposed inside the heat exchanger. When the temperature of the heat-sensing portion is high, the thermostat opens or closes the valve to reduce the flow amount of exhaust gas flowing into the second pipe (18).
