回答(1):

20~35 MPa。

在直喷式汽油机上,除了气态排放物之外,排放的颗粒数(PN)也是一项重要的课题。近年来的研究表明,直喷式汽油机的喷油压力已持续提高到20~35 MPa。

将喷油压力提升到更高的数值将为降低废气排放带来更大的提升潜力,但是燃油系统的部件及其在发动机和汽车上的集成已被发展到了技术极限,并对未来的开发提出了新的挑战。

发动机使用注意事项:

1、影响发动机的工作可靠和使用寿命:高温高湿环境十分有利于霉菌生长,使发动机产品发生霉变,导致金属机件锈蚀等,影响机组的工作可靠性并缩短使用寿命。

2、影响发动机的性能指标:高温高湿环境使发动机内部散热缓慢,机温升高,导致发动机输出功率下降并使其相应配件绝缘老化,会大大降低发动机的技术性能指标。霉菌会使电气设备的绝缘漆膜破坏脱落, 绝缘性能降低,导致发动机性能变坏。

3、影响发机的安全性:高温高压导致机件锈蚀,绝缘程度降低,既影响汽油安全性,又严重威胁人身安全。

汽油机的喷油压力为:自然吸气的一般是2.5-3.5bar, 直喷油管压力那就很高了一般为120-200bar。
