空燃比表 ( Air/ Fuel Ratio Meter)
油料在进入汽缸燃烧之前,必须先经过一段雾化的过程,将油与空气混合变成油气以利燃烧。而这雾化后的油气浓度比例就是A/F混合比。 过稀或过浓都不是件好事,尤其过稀的时候更是直接会有不良的影响, 例如排温温度升高。 A/F ( Air/Fuel ),空气对燃油的比例, 理想空燃比(14.7:1)时可得到最大的燃烧速度。提到浓度时尽量以油气\"浓"或\"淡"来形容,若是讲"高"或\"低"时则指的就是A/F比即为"空燃比"。所以油气\"浓"时,油多空气少,A/F比值"低"( 就是空气不足 );相反的,油气\"淡"时, 油少空气多,A/F比值高( 就是油气不足 )。汽油的燃烧空燃比22:1~8:1可安定运转的极限是18:1。所谓『稀薄燃烧引擎系统』技术(Lean Burn Combustion System) 就是让引擎在尽量接近燃烧界限的下限且不产生爆震的情况下运转。混合比的不同对车有什么样的影响呢?油气过稀,引擎容易过热,易导致熄火甚至缩缸的情形。油气过浓,较耗油,热车后容易熄火、长久下来易使引擎积碳,而积碳太过严重时也容易导致引擎过热。所以过稀或过浓都不是件好事,尤其过稀的时候更是直接会有不良的影响,空燃比计除了化油器车种因为没含氧感知器无法装~一般车种不分手排自排只要有含氧感知器都可以装,若是高阶的空燃比计(给重改的车款调整供油系统),连附加的感应器都会比原厂的精细及灵敏
