摘要： A correction apparatus for correcting an output of an oxygen sensor installed in an exhaust pipe of an internal combustion engine to measure the concentration of oxygen contained in exhaust gas. The apparatus works to execute a fuel cut operation to bring the pressure in the exhaust pipe to the atmospheric pressure and enters an under-atmosphere correction mode to sample an output of the oxygen sensor and determine a correction factor compensating for a deviation of the sampled output from a reference value representing an actual concentration of oxygen. The apparatus also works to calculate the pressure in the exhaust pipe after start of the fuel cut and determine whether the under-atmosphere correction mode is to be entered or not based on the pressure of exhaust gas, thereby ensuring the accuracy in correcting the output of the oxygen sensor regardless of a variation in the pressure of exhaust gas.

摘要： A correction apparatus for correcting an error in an output of an oxygen sensor such as an A/F sensor installed in an exhaust pipe of an internal combustion engine to measure the concentration of oxygen contained in exhaust gas. The apparatus works to determine a given parameter correlating with an actual concentration of oxygen within the exhaust pipe after start of a fuel cut event and also determine an oxygen concentration-corresponding output based on the given parameter which is a parameter corresponding to an output of the oxygen sensor considered to represent the actual concentration of oxygen correctly. The apparatus samples an output of the oxygen sensor during the fuel cut event and determines a correction factor based on the sampled output of the oxygen sensor and the oxygen concentration-corresponding output for use in correcting an output of the oxygen sensor when the engine is undergoing no fuel cut.

摘要： A gas concentration measuring apparatus which has a gas sensor designed to measure, for example, the concentrations of O2 and HOx contained in exhaust emissions of an automotive engine is provided. The apparatus includes a signal processing circuit which converts a current signal outputted from the gas sensor as a function of the concentration of either of O2 and NOx into a voltage signal. The gas sensor and the signal processing circuit are connected electrically through a conductor. The conductor has a length which is determined as a function of a level of the current signal outputted from the gas sensor. The weaker the level of the current signal is, the shorter the length of the conductor. This minimizes addition of electrical noises to the current signal outputted from the gas sensor.
