low speed engine meaning in English

低速发动机

The first rta52u type diesel engine developing and manufacture successful are marked as the marine low speed engine manufacture has jumped a new step , it can not only accelerate the advancing of diesel technical leave , but also push the development of the shipbuilding . while it is getting better economy benefit , also gaining far - reaching society benefit
首台rta52l机型的研制成功标志着造机水平己更上了一个新台级，它不仅促进了柴油机技术水平的提高，也推动了造船业的发展，在获得较好经济效益的同时，也驭得了深远的社会效益。
But there are some problems in normal turbocharger , for example , the low speed engine torque is deficiency , the engine ca n ' t works with full capacity when in part load , the transient response remains slow , to improve all the above , the variable geometry turbocharger ( vgt ) comes out to be an effective way
由于常规涡轮增压存在低速转矩不足、部分负荷经济性差和瞬态响应迟缓的问题，而采用可变几何截面涡轮增压是解决这些问题比较有效的方案。本文以vgt60增压器和yn4100qbz柴油机为研究对象，开发了可变几何截面增压器电控系统硬件。
