摘要:
A water pump attachment structure of a water-cooled internal combustion engine is provided to facilitate the maintenance of a valve train. A water pump attachment structure of a water-cooled internal combustion engine includes a semicircular cut-away surface of a water pump holder opposed to a semicircular surface of a cylinder head to form a water pump support circular hole. Screw members are passed through respective screw through-holes of the cylinder head and threadedly engaged with internal thread holes of the water pump holder. Thus, the water pump holder is fastened to the cylinder head. A water pump is fitted into and secured to the water pump support circular hole. A cylinder head cover is attached to the cylinder head by allowing their mating surfaces to conform with each other with the water pump holder liquid-tightly sandwiched therebetween.

A base sequence detection apparatus is provided with a channel formed on a base sequence detection chip. Working electrodes are formed along the channel and include a probe immobilized thereon, counter electrodes are formed on the inner surface of the channel and, reference electrodes are formed on the inner surface of the channel. An introduction port introduces solution or air from the upstream side of the channel, a delivery port delivers the solution or air in the channel, and the sample is injected into the channel through a sample injection port.
摘要:
A belt continuously variable transmission apparatus having a case which includes a power transmission case (which is part of a crankcase of an engine), a power transmission case cover, and an actuator cover assembled forwardly of the power transmission case cover (displaced forwardly on a vehicle body). The actuator cover is formed as a separate member from the power transmission case cover, and supports a motor for driving a movable part of a driving pulley. In addition, the actuator cover covers a gear system. The actuator cover is integrated with a cover of the water pump. The resulting configuration improves the assembling of the actuator cover of the belt continuously variable transmission apparatus.
摘要:
A two-step self-servowriting process first writes an intermediate pattern based on a reference pattern, and then writes a final pattern based on the intermediate pattern, wherein the reference pattern can be a printed media pattern. Such an approach can be utilized to reduce the noise/runout, eliminate timing eccentricity, and increase the sample rate of the final pattern. The final pattern should be written as a 3-step-per-track, trimmed (or untrimmed)-burst pattern, while the intermediate pattern can be written as a 1.5-step-per-track, trimmed (or untrimmed)-burst pattern. Since half of the steps servowriting the intermediate pattern can be omitted under such a scenario, approximately half of the servowriting time can be saved. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
摘要:
A blowby gas ventilation system for an internal combustion engine capable of preventing oil from being diluted by efficiently and quickly exhausting a blowby gas together with a water content and the like from a crank chamber through forced ventilation of the crank chamber. The blowby gas ventilation system is intended for a four-stroke-cycle internal combustion engine. The system includes a fresh air introduction pipe, through which fresh air is sent from an outside of the internal combustion engine through a throttle portion to a crank chamber. The system also includes a blowby gas return passageway, through which the blowby gas is returned back to a downstream side of an air cleaner.
摘要:
A fuel injection device is installed in a cylinder head of an internal combustion engine in such a manner that a fuel injection port thereof faces a curved intake passage formed in the cylinder head. Fuel is injected from the fuel injection device directly toward a wall surface of the intake passage without aiming at an intake port.
摘要:
To further enhance the durability of a fuel injection apparatus, to protect the fuel injection apparatus from external force by a simple configuration and to make it possible to readily perform an assembling operation or a maintenance or inspection operation of an engine on which the fuel injection apparatus is mounted. A motorcycle includes an engine having a cylinder extending forwardly and substantially horizontally. An intake port extends substantially rearwardly from an upper portion of a cylinder head of the engine, and a fuel injection apparatus for injecting fuel into a combustion chamber through the intake port, is disposed in the proximity of the cylinder head. A mounting boss is provided on an outer face of the intake port rearwardly of the fuel injection apparatus. The fuel injection apparatus is mounted on the mounting boss.
