Abstract: PURPOSE: A control device and method for monitoring oxygen sensors are provided to alarm the change of oxygen sensors to a driver when the first oxygen sensor and the second oxygen sensor are installed wrongly. CONSTITUTION: A first oxygen sensor(410) outputs an electric signal according to the change of an air fuel ratio of exhaust gas by installing between an engine and a catalytic unit. A second oxygen sensor(420) outputs an electric signal according to an air fuel ratio of final exhaust gas by installing in the back of the catalytic unit. A counter unit(430) counts a number of the first oxygen sensor to cut across 0.5V for a certain time. A memory unit(440) stores a set critical cut value of the first oxygen sensor. An engine control unit(450) outputs an alarming control signal to alarm the combined status of the first oxygen sensor according to the comparison between the cut number and the set critical cut value. An alarming unit(460) alarms the combined status of the first oxygen sensor according to the alarming control signal. Thereby, the wrong installation of the oxygen sensors is detected easily. Moreover, the increase of exhaust gas over the air fuel ratio is suppressed.

Abstract: PURPOSE: A method for controlling fuel injection of an engine in vehicle is provided to improve a driving comfort by preventing a lean peak of an air/fuel ratio caused by fuel injection reduction factors. CONSTITUTION: When power is applied to a vehicle, all parameters are initialized(S100). After an engine is ignition-on, if a cooling water temperature exceeds a first predetermined value, a fuzzy duty value is determined so as to calculate fuel injection reduction factors and so as to determine whether or not a driver intends to carry out a sudden acceleration(S120). Then, it is determined whether or not a lean peak of an air/fuel ratio is generated in an acceleration state of the vehicle. If the lean peak of the air/fuel ratio is generated, the fuzzy duty is set to 0% for a predetermined time period(S190) and fuel injection reduction factor is set to 1.0(S200). Then, a control signal is outputted in order to control an amount of fuel(S210,S220).
