摘要： An intake parameter estimating device is provided for estimating a tuning frequency of an internal combustion engine, which in turn can be used to estimate an intake air pressure of the internal combustion engine. The intake parameter estimating device basically has a fundamental frequency calculating section, an engine rotational speed detecting section and a tuning frequency calculating section. The fundamental frequency calculating section calculates a fundamental frequency of a pressure wave inside an air intake pipe based on a shape of the air intake pipe and speed of sound. The engine rotational speed detecting section detects an engine rotational speed. The tuning frequency calculating section calculates a tuning frequency of the pressure wave inside the air intake pipe based on the fundamental frequency and the engine rotational speed. The tuning frequency can then be used to estimate the intake air pressure of the internal combustion engine.

摘要： An EGR control method and unit for an internal combustion engine includes an EGR passage configured to recirculate a portion of an exhaust gas from an exhaust system to an intake system. An EGR valve, disposed in the EGR passage, is configured to control an amount of EGR, and an index calculator is configured to calculate a surge-increase index according to a variance in rotation of the engine. A detector is configured to compare the surge-increase index with a determination threshold to detect a surge increase, an adjuster is configured to adjust a correction value relative to a target amount of the EGR according to an output of the detector, and a target-amount calculator is configured to calculate the target amount of the EGR by subtracting the correction value from a reference target amount of the EGR determined based upon an engine operating condition.

摘要： An intake port (4) is connected to a combustion chamber (6) of an internal combustion engine (1) via an intake valve (15), and a volatile liquid fuel is injected from a fuel injector (21) provided in the intake port (4). The controller (31) calculates a suspension ratio in the combustion chamber (5) of the injected fuel according to the particle diameter of the injected fuel (52-56), calculates an amount of fuel burnt in the combustion chamber (6) based on the suspension ratio (57), calculates a target fuel injection amount based on the burnt fuel amount (75, 76), and controls a fuel injection amount of the fuel injector (21) based on the target fuel injection amount (76). Precise fuel injection control can be performed without performing adaptation experiments, based on particle diameter data for different fuel injectors by taking the particle diameter as a parameter.

摘要： Electronic devices are provided with electrically conductive interconnections which are formed on the insulator material. Such electronic devices include, for example, thin film semiconductor devices (TFT), metal-insulator-metallic type non-wiring elements (MIM), solar cells, Large Scale Integration devices (LSI) or printed-wiring boards. At least a part of the electrically conductive interconnections are made of .alpha.-structure tantalum (Ta) which contains hydrogen. The .alpha.-structure tantalum does not have cubical crystals in its crystal system, but rather has body-centered cubes (bcc). The resistivity of the .alpha.-structure tantalum is from about 20 .mu..OMEGA. centimeters to about 60 .mu..OMEGA. centimeters. When hydrogen is included within this .alpha.-structure tantalum film, small amounts of nitrogen may be contained along with the hydrogen in the film. When a semiconductor layer is directly formed on the lower conductive layer, the upper conductive layer contains, as a primary component, the hydrogen contained .alpha.-structure tantalum.
