当前,世界各国对轻型可空运装甲战车的军事需求,促进了车辆各个部件向轻量化和小型化的方向发展。在坦克上,发动机是最重要的部件之一,它被称为“坦克的心脏”。现有坦克柴油发动机的尺寸和重量都较大,为了减小其重量和尺寸,对发动机的改造理所当然成为重点。当然,既要缩小发动机的体积和重量,又要保持甚至增大其功率,这并不是一件简单的事情,可以说是一种挑战。接受这一挑战的是德国MTU公司,它负责研制重量更轻、更紧凑的高功率密度发动机。作为军用柴油发动机的主要供应商,MTU公司已完成了890系列高功率密度发动机的研制工作。与该公司早期的装甲战车用柴油发动机相比较而言,新研制的发动机具有重量更轻、体积更小等特点,是坦克柴油发动机中的一朵奇葩,可称得上坦克“心脏”新秀。凭借这一优势,890系列发动机也成为美国未来战斗系统和英国未来快速反应系统平台的候选发动机,而该系列中的一款机型已被德国陆军“美洲狮”新型步兵战车选用。
At present, the military needs of various countries in the world for light, air-transportable armored combat vehicles have promoted the development of lightweight and miniaturized vehicles. On the tank, the engine is one of the most important parts, it is called the “heart of the tank.” The size and weight of the existing tank diesel engines are large, in order to reduce its weight and size, of course, become the focus of the engine transformation. Of course, not only to reduce the size and weight of the engine, but also to maintain or even increase its power, this is not a simple matter, can be said to be a challenge. This challenge was met by MTU Germany, which is responsible for the development of lighter and more compact high-density engines. As a major supplier of military diesel engines, MTU has completed the development of the 890 series of high-power-density engines. Compared with the company’s early armored combat diesel engine, the newly developed engine has the characteristics of lighter weight and smaller size. It is a wonderful work in a tank diesel engine and can be regarded as the "heart Rookie. With this advantage, the 890 series engines are also candidates for future battle systems in the United States and future rapid reaction system platforms in the UK, and one of the models in this series has been selected for use by the German Army’s Puma new infantry fighting vehicle.
