ADD公司新开发成功的ADD30V型中速柴油机的平均有效压力达 2 7MPa ,活塞平均速度 12 0m/s,最高燃烧压力 2 0MPa ,强化系数Pe·Cm高达 32 3MPa·m/s。该型柴油机的重量比原有相同功率的中速机轻 30 % ,其燃油消耗率仅为 184g/kWh。排烟浓度和NOx排放分别为 0 0 2 4g/m3和 90 0PPm ,并具有与原有柴油机同样良好的耐久可靠性。为实现上述高性能 ,该机采用了包括铸钢机体、RR锻钢曲轴、钢头球铁裙活塞、陶瓷喷涂缸套和活塞环以及单气门结构在内的一系列突破性新材料和新技术
ADD company newly developed ADD30V medium-speed diesel engine, the average effective pressure of 2 7MPa, the average piston speed 12 0m / s, the maximum combustion pressure of 20MPa, strengthening coefficient Pe · Cm up to 32 3MPa · m / s. The weight of this diesel engine is 30% lighter than that of the original medium-speed machine with the same power, and its fuel consumption rate is only 184g / kWh. Exhaust smoke concentration and NOx emissions were 0 0 2 4g / m3 and 90 0PPm, respectively, with the same good durability as the original diesel engine. In order to achieve the above high performance, the machine uses a series of breakthrough new materials and technologies including the cast steel body, the RR forged steel crankshaft, the steel head iron skirt piston, the ceramic coating cylinder liner and the piston ring, and the single valve structure
