摘要： Rotation recognition means for recognizing a revolution of a crankshaft based on the cylinders before the combustion cycle of a cylinder in question is provided. When the supply of fuel by injection from an injector to a certain cylinder of the six cylinders has become impossible, then control is performed to change the number of cylinders targeted by the rotation recognition means so as to recognize the revolution of the crankshaft for all six cylinders whose combustion cycles are consecutive prior to the combustion cycle of the cylinder in question, and to stop the supply of fuel from the injectors for supplying fuel to cylinders whose combustion cycles are equally spaced from the cylinder to which the supply of fuel is not possible, so that the spacing between the combustion cycles in the cylinders whose combustion cycles come before and after and sandwich the cylinder to which the supply of fuel is not possible becomes uniform.

摘要： The present invention regenerates optical signals in an intact optical state according to a low-speed optical clock. In one embodiment, an optical splitter applies a portion of optical pulse signals to a clock recovery circuit and the rest to an optical splitter. The optical splitter applies half of the input signal to an optical regenerator and the rest to another optical regenerator. The clock recovery circuit regenerates an electric clock signal with half the frequency of the input optical pulse and applies the clock to an optical clock pulse generator. The optical clock pulse generator generates an optical clock signal with half the frequency of the input optical pulse whose phase matches with that of the optical signal at the optical regenerator. An optical regenerator regenerates the optical signal from the optical splitter in an intact optical state. A polarization combiner combine the optical signals from the optical regenerators in mutually orthogonal polarization.
