    摘要： In a multi-cylinder engine, amounts of fuel injection supplied to respective cylinders are individually corrected on the basis of a signal from A/F sensors in the number less than the number of cylinders of the engine, for example, one A/F sensor, so that the air/fuel ratios for respective cylinders are feedback-controlled at a substantially uniform predetermined air/fuel ratio. Therefore, it is possible to perform precise air/fuel ratio control so as to accurately maintain the air/fuel ratio of the engine at the stoichiometric air/fuel ratio, to reduce the concentrations of HC, CO, and NOx in exhaust gas.

    摘要： The present invention relates to a magnetic recording/reproduction device (such as VTRs and DATs). A cue signal becomes a mark of its position for automatic operation and automatic editing and is to be recorded in advance with the contents of a program. The frequency of the cue signal is selected within the audio signal band. On an auxiliary audio track (24) in a magnetic tape (21), an audio signal as well as a cue signal is recorded in time division manner. Determination is made of a correct cue signal by providing a mute period before the cue signal recording region and detecting a cue signal by a filter after the detection of a mute period. The frequency ratio of the cue signal to control signal (CTL) is determined by a counter (6) with a CPU (7) being used to identify a cue signal in response to the frequency ratio. By dividing the reproduced signal into blocks, the cue signal is detected from the cycle number distribution of the frequency. Through use of the invention, the efficiency of cue signal recording/reproduction can be improved and the circuitry used to precisely detect it can be simplified.
