PURPOSE:To normalize the tire surface temperature and reduce rolling resistance by detecting the surface temperature of a tire and controlling cold air or hot air from an air conditioner, traveling wind and flow rate of purified exhaust gas of a muffler. CONSTITUTION:Surface temperature signals of a tire 8 from an infrared rays sensor 2 are input into a control unit 1 and respective valves 3 to 5 are controlled. Cold blast or hot air 'a' from an air condition and running wind 'b' are selected by a changeover valve 3 and this air quantity is controlled by a cold blast control valve 4 in accordance with the control command. Purified exhaust exhaust gas 'd', which is the purified exhaust gas of a muffer 9, is sucked through a bypass passage 10 and a hot air control valve 5 controls the discharge by the control command. Air discharged through the cold air and hot air control valves 4, 5 is mixed by a mixer 6 and discharged to the tire 8 through a tire house 7. Thus the surface temperature of the tire 8 is rapidly brought to an appropriate value, and fuel consumption, grip performance and cornering performance can be improved by reduction of rolling resistance. |
