The "Shinshu Maru" is the first ship equipped with Vulcan geared Diesel engines in Japan, and the propelling machinery consists, in brief, of two sets of Mitsubishi single acting, four-stroke-cycle, airless-injection, reversible Diesel engines of special design and two Vulean hydraulic couplings with reduction gearing. These engines develop a total normal output of 2,700 B.H.P. at 420 r.p.m., and this speed is redneed to 90 r.p.m. at the propeller shaft. The trials were carried out at one fifth loaded condition, and the resnlts were quite satisfactory as follows : a) The maximum speed of 16302 knots was recorded with two engines at 100 r. p. m. on the propeller shaft, and 12.246 knots with one engine at 72 r. p. m. b) The minimum speed of 3.60 knots was recorded with one engine at 25 r. p. m. on the propeller shaft. c) Entirely uniform torque in the propeller shaft was recorded by the torsiou recording apparatus. d) Easy manoenvering. e) Reliability of running, etc.
