从减少发动机的燃油消耗量以及RTA超长行程系列发动机供应到市场以来的销路来看都是令人满意的。Winterthur设计者们在这方面取得进一步的进展。最大尺寸的发动机在经济功率时转速低达55r/min,这就表明在相同活塞速度下其程约近三米长,并有宽的机座以适应于相应的曲柄行程。新的RTA84M补充了现有的RTA84系列,功率从10120～55200ps,转速在55～75r/min,在常用功率下有效燃油消耗率低达118g/ps.h,在装有余热回收涡轮时他可下降到116g/ps·h。
From reducing the fuel consumption of the engine and RTA long stroke series engine supply to the market since the sales point of view are satisfactory. Winterthur designers made further progress in this area. The maximum size of the engine at low speeds of 55r / min at economical power means that it travels nearly three meters at the same piston speed and has a wide stand to accommodate the corresponding crank travel. The new RTA84M complements the existing RTA84 series with power rates ranging from 10120 to 55200 ps at 55 to 75 rpm and effective fuel consumption as low as 118 g / ps.h at typical power, with a waste heat recovery turbine Down to 116g / ps · h.
