顾氏系统与其他系统在改善舰船用高增压柴油机性能方面的计算比较

Comparison of Gus System with VGT, STS and GRS in lmproving Performance of High Turbocharged Marine Diesel Engines under Light Load Operation

以有效压力提高到２．５ＭＰａ的ＭＡＮＢ＆Ｗ６Ｌ５８／６４柴油机为对象，将集配气与供油正时控制于一体的顾氏系统，与改善高增压柴油机低工况性能的其他措施如变截面涡轮、相继涡轮增压及放气系统进行了理论计算和比较．结果表明，顾氏系统在改善舰船用高增压柴油机性能方面优于其他３种方案．

The numerical computation and comparison of Gus system with variable geomitry turbocharger, sequential turbocharger system and gas release system in improving the performance of high turbocharged marine diesel engines such as 6L58/64 under light load operation are carried out. The result shows that Gus system is better than the other three.
