一、引言在题为“M601大型四冲程柴油机”报告的开头,对图1给出的喷射压力和气缸压力曲线作一简短的评述。它是用高粘度即700厘沲的裂化重油工作时测得的。这种裂化重油预计很可能就是未来的船用燃料油。柴油机的这些重要曲线呈经典形式的过程表明,在正常的前 I. INTRODUCTION At the beginning of the report entitled “M601 Large Four-stroke Diesel Engine”, a brief review of the injection pressure and cylinder pressure curve given in Figure 1 was made. It is measured with a cracked heavy oil with a high viscosity of 700 centistokes. This cracked heavy oil is likely to be the future of marine fuel oil. These important curves of diesel engines show the classic form of the process before normal
