摘要： PROBLEM TO BE SOLVED: To detect a pre-scuffing phenomenon in a large multi-cylinder two-cycle diesel engine. SOLUTION: A method is for detecting a pre-scuffing condition in a large multi-cylinder turbo-charge type two-cycle diesel engine. In the method, the temperature of a cylinder wall in an upper region of a cylinder is continuously or intermittently measured, and a determination whether the temperature of the cylinder fluctuates with the time is done. In the case wherein a peak interval or a dip interval of the temperature fluctuation of the cylinder to be measured exists in a range of nearly 6 minutes to nearly 18 minutes, and in the case wherein a temperature difference between the peak and the dip in the temperature fluctuation exists in a range of nearly 25 degrees to nearly 65 degrees, a pre-scuffing alarm is issued.

摘要： PROBLEM TO BE SOLVED: To provide a crank shaft improved to transmit relative great torque while avoiding defects due to known arrangement, by using easy and cost advantageous means.
SOLUTION: To solve the above issue, the crank shaft includes a conical body 9 formed tapered in view from the inserting direction, where a front region of an engaging strut 5 in view from the inserting direction is connected to the rear region of the engaging strut, and a stopper ring 10 mounted thereon for preventing the axial movement of the engaging strut relative to a crank web 1. The conical body follows the rear region of the engaging strut, and so there is no need for stepwise dimensional adjustment of the engaging strut and a crank web hole corresponding thereto. As a result, a clearance may not be formed to assure reliable shrinkage joint over the total length of the engaging strut. The average diameter of the conical body is basically larger than the diameter of the front end. This is advantageous in achieving transmission torque.
