摘要： To reliably prevent knocking in all of the cylinders of a multicylinder engine by detecting an output signal from a knock sensor provided for only one of the cylinders. A cylinder barrel is formed with a knock sensor base on the side surface of only the third cylinder and a vibration type knock sensor is mounted on the knock sensor base. A water jacket is formed in an upper portion of the wall of the cylinder barrel. The knock sensor base is formed below the water jacket so as to prevent a problem such that knocking vibrations may be absorbed by the cooling water in the water jacket to cause a reduction in sensitivity of the knock sensor.

摘要： [Problem] In known methods, an improvement of the coercive force is realized by allowing the Dy metal or the like to present selectively in crystal grain boundary portions of a sintered magnet. However, since these are based on a physical film formation method, e.g., sputtering, through the use of a vacuum vessel, there is a mass productivity problem in the case where large amounts of magnet is treated. Furthermore, there is a magnet cost problem from the viewpoint that, for example, an expensive, high-purity Dy metal or the like must be used as a raw material for film formation. [Solving Means] A method for modifying grain boundaries of a Nd—Fe—B base magnet characterized by including the step of allowing an M metal component to diffuse and penetrate from a surface of a Nd—Fe—B base sintered magnet body having a Nd-rich crystal grain boundary phase surrounding principal Nd2Fe14B crystals to the grain boundary phase through a reduction treatment of a fluoride, an oxide, or a chloride of an M metal element (where M is Pr, Dy, Tb, or Ho).
摘要翻译： [问题]在已知的方法中，通过使Dy金属等选择性地存在于烧结磁体的晶界部中，可以实现矫顽力的提高。然而，由于这些基于物理成膜方法，例如溅射，通过使用真空容器，在处理大量磁体的情况下存在批量生产率问题。此外，从例如必须使用昂贵，高纯度的Dy金属等作为成膜原料的观点出现磁铁成本问题。 [解决方案]一种用于改变Nd-Fe-B基础磁体的晶界的方法，其特征在于包括以下步骤：允许M金属组分从具有通过氟化物，氧化物或氯化物的还原处理将包围主要Nd 2 Fe 14 B的富Nd晶界相结晶到晶界相 M金属元素（其中M为Pr，Dy，Tb或Ho）。

摘要： A fuel injection control apparatus is capable of supplying a proper amount of fuel by improving response when the throttle position is abruptly changed. The fuel injection control apparatus includes an electronic control unit for determining a fuel injection time period for a fuel injection system, based on the engine speed and the throttle position. The electronic control unit is operable to determine a base fuel injection time period based on engine speed and throttle position to start fuel injection, and adjusts the initial fuel injection time period thereafter, based on changes in the engine speed and the throttle position.
