关于发动机系统以及他周边的各种装置,我们会依照其关联做分类与介绍。跟燃料有关系的:◎喷油嘴(Fuel injectors)喷油嘴必须在最精确的时间将燃料喷入汽缸之中。(四缸发动机常态之下就会有四只独立的喷油嘴)◎辛烷值(Octane rating)如果车辆设计用于辛烷值较低的燃料,而车主却反而用了辛 About the engine system and the various devices around him, we will classify and introduce them according to their relationship. Related to fuel: ◎ Fuel injectors Fuel injectors must inject fuel into the cylinder at the most precise time. (Four-cylinder engine normally has four separate injectors under normal conditions.) Octane rating If the vehicle is designed for a fuel with a lower octane number and the owner is using it instead
