Abstract: A control device includes an electronic control unit. During deceleration of the engine, when a temperature of a three-way catalyst is equal to or higher than a predetermined temperature and execution conditions of fuel cut processing are established, the electronic control unit executes first control for closing an exhaust shutoff valve, while fuel injection and ignition are continued. When the exhaust shutoff valve reaches the closed state in the first control, the electronic control unit executes second control for bringing the engine into an intake control state in which the intake throttle is closed and an EGR valve is in a predetermined open state. In the second control, the electronic control unit executes the fuel cut processing by stopping the ignition before the engine is brought into the intake control state and stopping the fuel injection after the engine is brought into the intake control state.

Abstract: A temperature control system includes a heater core utilizing heat of a heat medium; an engine heat exchanger utilizing exhaust heat of an engine to heat the heat medium; a condenser utilizing heat other than the exhaust heat to heat the heat medium; a heat circuit having the heater core and condenser; a communication flow path making the engine heat exchanger communicate with the heat circuit; and a connection state switching mechanism switching a flow state of the heat medium, between a first state and a second state. In the first state, the heat medium flows through the heat circuit, while flowing through the heater core, and in the second state, the heat medium flows through the heat circuit without flowing through the heater core. The heat circuit is arranged at a front of a passenger compartment, and the engine heat exchanger is arranged at a rear of the compartment.

Abstract: A vehicle-mounted temperature controller has a first heat circuit and a refrigeration circuit. The first heat circuit has a first radiator exchanging heat with outside air, a first heat exchanger, and a first pump, and configured so that a first heat medium is circulated therethrough. The refrigeration circuit has the first heat exchanger discharging heat from the refrigerant to a first heat medium to make a refrigerant condense, a second heat exchanger absorbing heat to the refrigerant to thereby make the refrigerant evaporate and to cool an object to be cooled, and a compressor, and is configured so that the refrigerant circulates through the first heat exchanger and the second heat exchanger and thereby a refrigeration cycle is realized. When the object to be cooled starts being cooled, the compressor is started up after the first pump is started up.
