大多数的柴油机制造者都是想要在保持压力不变的情况下来提高柴油机的功率、柴油机重量比,要达到这一目的的最有效的方法是增大气缸内径,以增加气缸工作容量。如果要保持柴油机的总尺寸不变,这只有靠增加现有缸套的内径才有可能。满足这一要求的可能受到铸铁材料机械性能低的限制。一种可行的办法就是采用强度较高的 Most diesel engine manufacturers want to increase the diesel engine power while maintaining the same pressure. The most effective way to achieve this is to increase the cylinder bore to increase the working capacity of the cylinder. If you want to keep the total size of the diesel engine unchanged, this is only possible by increasing the inner diameter of the existing cylinder liner. Meeting this requirement may be limited by the low mechanical properties of the cast iron material. A viable solution is to use a higher intensity
