    摘要： An air intake arrangement for an internal combustion engine comprising : a main air intake conduit leading to a gas intake valve (241) for respective engine cylinders (206) and including a main air intake passage (202), a main collector chamber (204) and independent branching air intake passages (205) for the respective engine cylinders (206) connected in series ; a throttle valve (203) disposed in the main intake air passage (202) for controlling the flow rate of air passing therethrough ; an auxiliary air intake passage (210) bypassing the main air intake conduit, an inlet port of the auxiliary air intake passage (210) opens into the main air intake passage (202) at the upstream of the throttle valve (203), an outlet port (213) of the auxiliary air intake passage (210) opens into the respective independent branching air intake passages (205) near the gas intake valve (241) for the respective engine cylinders (206) in such a manner that gas blown-out from the auxiliary air intake passage (210) induces a gas swirl in the respective engine cylinders (206) ; an intake air control valve (211) disposed in the auxiliary air intake passage (210) for controlling the flow rate of air passing therethrough ; and a control unit (222) which determined an operating condition of the internal combustion engine and controls an opening degree of the intake air control valve (211) based on the determined engine operating condition.

    摘要： The invention relates to a method and apparatus for controlling internal combustion engines in which the operating conditions (such as vehicle speed) and the control conditions (such as throttle opening degree) of operating elements (5-8) of the internal combustion engine are used to determine a resistance index (such as an equivalent gradient) for specifying the driving force corresponding to the operating conditions (5-8) under the prevailing load conditions. Further, this resistance index data is accumulated, so that the operating elements (5-8) are controlled on the basis of a target operating condition and a corresponding resistance index.

    摘要： A method for feedback controlling air-fuel ratio of the mixture supplied to an internal combustion engine having a plurality of cylinders comprises the steps of detecting (534, 536) respective air-fuel ratios of the exhaust gas from the respective cylinders with an air-fuel ratio sensor having a substantially linear output characteristic over a wide variation of air-fuel ratio of the exhaust gas; calculating (538) an average air-fuel ratio by using the latest detected air-fuel ratios of the respective cylinders; determining (540) a fundamental feedback correction coefficient β₀ for a cylinder of which air-fuel ratio is feedback controlled next; retrieving (542) a learning correction coefficient β₁ for the cylinder of which air-fuel ratio is feedback controlled next from a learning map prepared by learning for the corresponding cylinder; and determining (552) new learning correction coefficients β₁ for the respective cylinders using respective deviations of the respective detected current air-fuel ratios from the latest average air-fuel ratio calculated in the previous step, whereby air-fuel ratio control at any desired air-fuel ratio is carried out with a high accuracy and with a uniform air-fuel ratio throughout the whole cylinders.

    摘要： A method of a position measurement in which information about satellite orbits and information about time are received from satellites to determine own posi­tion. The method includes a step to calculate a direc­tion in which an error occurs based on a position of a satellite used (100) and a step to determine own position by use of road map information in the direction of the error (202-205).
