Title: Control device for internal combustion engine
Inventor: GOYA YOICHIRO
IPC: F02D45/00
Filed: 2008-09-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine avoiding breakage of an air-fuel ratio detection element due to getting wet, accelerating heating of the air-fuel ratio detection element, and making temperature of the air-fuel ratio detection element reach activated temperature at an early stage by preventing steam in exhaust gas from being easily condensed at an element cover by dropping steam concentration in exhaust gas.  <P>SOLUTION: The control device forcibly cools exhaust system components (time t0-t3 in Fig.5) when the element cover temperature TC is lower than a first temperature (dew-point temperature in case the steam concentration of exhaust gas is normal) TCthH. Consequently, since steam in exhaust gas becomes dew condensation water in an exhaust gas passage, steam concentration of the exhaust gas reaching the air-fuel ratio sensor drops. Since dew-point temperature of the element cover, therefore, drops to a second temperature TCthL, heat generation quantity of a heater is increased when the element cover temperature TC gets to the second temperature TCthL or higher (refer time t1 or later).  <P>COPYRIGHT: (C)2010,JPO&INPIT
