Title: Heater control device of air/fuel ratio sensor for internal combustion engine
Inventor: NAGAI TOSHINARI
IPC: G01N27/409
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To suppress discharge of a battery caused by preheating, in the case of a heater control device for an air/fuel sensor having the preheating function of heating the air/fuel sensor prior to the start of an internal combustion engine.
