A system of the combination of a high revolution reciprocating engine and a low pressure turbine, both geared to the main shaft line of a steam ship, has been known in this country as Uraga 2-DC system. A paper was read by one of the authors of this paper, at the autumn meeting of this Society in the year 1936, describing the actual performances of the engines in question. The same system has also been described in the same author's book entitled “Hakuyo Rendo Kiki” (The Marine Combination Steam Machinery).
The present parper deals with some latest improvements upon the design of the part of the reciprocating engine of the said system, and suggestions are given in it to the effect of
1. Adaptability of higher steam pressure and higher temperature
2. Increase of power due to adopting higher piston speed
3. Better efficiency ratio due to improvement of valves and valve operating gears.
4. Improvement of symultaneously operating manoeuvring gears of the engine and turbine, and also suggestion of an electrically operated reversing and control system, which might be worked at remote positions.
This new system will be designated NAC SYSTEM.
