Abstract: An in-vehicle temperature control system includes a refrigeration circuit including an inter-media heat exchanger that dissipates heat from a refrigerant to a heat medium, the refrigeration circuit being configured to realize a refrigeration cycle, and a heat circuit including a heater core, the inter-media heat exchanger, and an engine heat circuit. The heat circuit includes an adjusting valve. When heating is performed by using heat obtained by the refrigeration cycle, the adjusting valve is controlled to a first state where the heat medium flows into the heater core from the inter-media heat exchanger, and when heating is performed by using heat obtained by an internal combustion engine, the adjusting valve is controlled to a second state where the heat medium flows into the heater core from the engine heat circuit.

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: An internal combustion engine which has a plurality of cylinders comprises port fuel injectors, cylinder fuel injectors, an exhaust purification catalyst arranged at an engine exhaust passage, a downstream side air-fuel ratio sensor, and a control device controlling a combustion air-fuel ratio and a ratio of feed of fuel from two fuel injectors, wherein the control device is configured to be able to perform average air-fuel ratio control where it alternately controls an average air-fuel ratio to a rich air-fuel ratio and a lean air-fuel ratio and inter-cylinder air-fuel ratio control where it controls the combustion air-fuel ratios of the cylinders so that the combustion air-fuel ratios of the cylinders become richer and leaner than the average air-fuel ratio. The control device controls the feed ratio so that an amount of fuel feed from the port fuel injectors becomes greater than an amount of fuel feed from the cylinder fuel injectors for cylinders where the combustion air-fuel ratio is made leaner than the average air-fuel ratio when the inter-cylinder air-fuel ratio control is being performed.
