Abstract: An exhaust gas recirculation mechanism of an engine. Some of exhaust gas discharged from combustion chambers is recirculated to the combustion chambers through an EGR passage. An EGR valve is located in the EGR passage for adjusting the amount of recirculated exhaust gas. Foreign matter contained in exhaust gas in the EGR passage adheres to a valve shaft of the EGR valve that is exposed in the EGR passage. Normally, the opening amount of the EGR valve is controlled in accordance with the running state of the engine. If the opening amount of the EGR valve, which is determined based on the running state of the engine, is greater than a predetermined value, an ECU judges that the EGR ratio will fall within an acceptable range even if the EGR valve is fully opened from the current position. The ECU therefore forces the EGR valve to open fully. As a result, the foreign matter adhered to the valve shaft is removed without deteriorating the running condition of the engine.

Abstract: An air conditioning system 100 may include a compressor 101 having a driving chamber 111, a heating circuit 310 and a controller 203. This system may release high pressure refrigerant from the compressor discharge port 141 into the compressor driving chamber 111 by opening a capacity control valve 181 when the discharge pressure of the refrigerant discharged from the compressor 101 exceeds a predetermined reference value. By increasing the pressure within the driving chamber 111, the compressor discharge capacity can be reduced. As a result, the discharge pressure of the compressor 101 will be reduced by the reduction in the compressor discharge capacity. Further, the controller 203 may decrease the reference value in accordance with a value related to change in the discharge pressure. As a result, the capacity control valve 181 can be opened at an early stage of the increasing of the discharge pressure if the discharge pressure increases rapidly.
