Abstract: A fuel spray and a tumble collide with each other from approximately opposite directions in a cavity formed in a piston head so that a combustible mixture stays around a spark plug provided at an upper central part of a combustion chamber for an extended period of time. An upper opening of the cavity is elongated to both the left and right sides of a cylinder axis. The distance between a ceiling of the combustion chamber and a bottom surface of the cavity as measured parallel to the cylinder axis is smaller on the right side of the cylinder axis than on the left side thereof and largest at least at a point where the cylinder axis crosses the bottom surface of the cavity, and a portion of the cavity to the left of the cylinder axis has a larger volumetric capacity than a portion of the cavity to the right of the cylinder axis, whereby a strong tumble is maintained up to a fuel injection point, allowing satisfactory mixture strification.

Abstract: During stratified-charge combustion operation of a direct-injection spark ignition engine, at the cylinder compression stroke, a tumble is generated which flows between a spark plug electrode and a piston crown surface toward an injector. A fuel is injected from the injector in correspondence with the cylinder ignition timing by controlling the penetration of fuel spray from the injector to correspond to the tumble flow rate so that the fuel spray may go against the tumble, become a flammable mixture at the cylinder ignition timing and stay near the spark plug electrode. In the late stage of the compression stroke, diffusion of the flammable mixture is suppressed with squishes. Thus, fuel spray behavior in the combustion chamber is controlled to allow suitable mixture stratification over a wide engine operating condition range. This improves combustion quality and extends a stratified-charge combustion zone thereby providing enhanced fuel economy and power output.

Abstract: There are disclosed a mounting information-collecting device which is capable of collecting mounting information concerning mounted statuses of circuit boards with high accuracy and efficiency, as well as a connector and a mounting information-collecting method therefor. A light-emitting device emits an optical signal. A plurality of optical signal-processing elements each apply processing to the optical signal in a manner unique to a corresponding one of the circuit boards to thereby generate a processed optical signal. A mounting information-collecting device receives the processed optical signal and detects whether or not the processing has been applied, to thereby collect the mounting information.

Abstract: A control device for a direct injection engine having a catalyst provided in an exhaust passage for converting exhaust gases and an injector for injecting fuel directly into a combustion chamber, includes a temperature state identifier for judging the temperature state of the catalyst, a load condition detector for sensing engine load conditions, and a fuel injection controller for controlling fuel injection from the injector. The fuel injection controller performs quick light-off control operation by causing the injector to inject fuel in one-time injection mode during a compression stroke in a specific low-load operating range of the engine when the catalyst is in its unheated state where its temperature is below its activation temperature, and switching the mode of fuel injection to intake-compression stroke split injection mode in a specific high-load operating range of the engine.

Abstract: Proposed is a powder consisting of rare earth oxide-based composite particles having an average particle diameter in the range from 0.1 to 100 .mu.m, each of which has a composite structure consisting of a core of a rare earth oxide and a coating layer of a rare earth hydroxide, the coating layer of the rare earth hydroxide having an average thickness of at least 5 nm but not exceeding 10% of the average particle diameter of the composite particles. While a rare earth oxide powder is useful as a sintering aid of a ceramic powder which is used in molding usually in the form of an aqueous slurry, the composite particles when added to an aqueous slurry of a ceramic powder exhibit a remarkable effect as a viscosity stabilizer or gelation inhibitor of the aqueous slurry so that improvements can be obtained in the productivity of the manufacturing process and quality of ceramic products.

Abstract: An air-fuel control system for an internal combustion engine is equipped with an exhaust system having a catalytic converter, a linear O.sub.2 sensor and a .lambda.O.sub.2 sensor for feedback controlling an air-fuel ratio on the basis of output representative of oxygen content from at least the linear O.sub.2 sensor. The system delivers a target air-fuel ratio of a fuel mixture. A determinant output, based on which the air-fuel ratio is feedback controlled, is shifted from output from the linear O.sub.2 sensor to output from the .lambda.O.sub.2 sensor before the linear O.sub.2 sensor is effectively active.

Abstract: An intake system, for use with an internal combustion engine having a plurality of intake valves for each cylinder, includes a plurality of intake ports, opening into the combustion chamber side of the internal combustion engine at different distances from a spark plug of the cylinder. The intake valves are controlled to keep an intake port located at the shortest distance from the spark plug opened only slightly in an early intake cycle stage while opening the other intake ports at their desired timings. The intake port located at the shortest distance from the spark plug is subsequently opened at a desired timing, thereby aspirating a substantial quantity of air through the closest intake port at a later time than through the other intake ports.
