摘要: A hydraulic excavator includes a boom comprising an articulated first and second boom member, an arm, a bucket, a boom cylinder for operating the boom, an arm cylinder for operating the arm; and a bucket cylinder for operating the bucket. The boom cylinder is cooperatively associated with the boom to establish a geometry wherein, during operation, the axis of the boom cylinder can never pivot rearwardly across a dead point of the boom and therefore eliminate the possibility of dead locking of the boom during operation.

摘要: The present invention provides an internal combustion engine including an injection nozzle for injecting fuel. The injection nozzle is formed with a plurality of injection holes arranged in two rows concentrically relative to the center axis (L) of the injection nozzle. The injection holes in the upper row are arranged in a zigzag fashion relative to those in the lower row. Radially extending center axes (P) of the respective injection holes in the upper row are arranged on the periphery of a circle of which center is located at a position (O) on the center axis (L) of the injection nozzle, while radially extending center axes (P) of the respective injection holes in the lower row are arranged on the periphery of a circle of which center is located at a position (O) on the center axis (L) of the injection nozzle. The position (O) is spaced away from the position (O) by a predetermined distance (Z).

摘要: A method for setting the vehicle-engine torque comprises the step of: concentrating, in lower parts of operating ranges of engine speed of the engine, any of: operating ranges of engine speed of the engine, which ranges are determined by power output characteristics inherent in the engine; and the majority of operating ranges of engine torque. The method comprises the step of: selecting an acceleration torque set value at a time when acceleration conditions of a vehicle carrying the engine is detected by a detecting means, which acceleration torque set value is larger than a normal torque set value.
