Abstract
PURPOSE:To reduce power consumption in a suction air heater by attaching a cap to a casing which forms a ceramic heater housing along with a heating pannel and by making exhaust gas or cooling water pass through a space of the cap. CONSTITUTION:With an engine cool, a temperature of cooling water being -7 deg.C, for example, an opening-and-closing valve 27 is kept closed. When the engine is started under such conditions, a ceramic heater 15 of a suction air heater 10 begins to be electrified to heat a heating pannel 11 to approximately 80 deg.C so that fuel from a carburetor 3 is enhancively atomized after collision against the pannel. When the temperature of cooling water is increased up to 40 deg.C or so, an opening-and-closing valve 27 is opened and allows a negative pressure to be transmitted to an EGR control valve 23 to open. Exhaust gas is resultantly fed back into a suction air passage 4 through a space 21 of the heater 10 while a casing 12 is heated thereby. When the temperature of the water is further increased, electrification of the heater 13 is stopped, however, reduction in temperature of the heating pannel 1 may be minimized due to circulation of exhaust gas.
