补气阀 meaning in Chinese

gulp valve

This paper investigates the structural parameters of air inlet pipe , air compensating pipe and air compensating valve which influence the air compensation of air compensating valve for motorcycle catalytic converter , the position of air compensating hole , and the relationship of air compensating pressure with engine speed
本文就影响摩托车催化转化器补气阀补气量的进气管、补气管、补气阀的结构参数，以及补气孔的位置、补气压力随转速的变化关系等进行了探讨。
The air - fuel ratio closed loop control adjusts the air - fuel ratio near the theoretical value by controlling the supplementary air of supplementary valve based on the signals of oxygen sensor , running speed and water temperature and which is necessary condition for three - way catalyst converter to work more efficiently
空燃比闭环控制是根据氧传感器、转速和水温信号，控制化油器后补气阀补气将空燃比控制在理论值附近，为三元催化转换器高效工作准备必要条件，使其最大限度降低尾气排放。
