摘　　要：为了提高燃油蒸发排放控制系统(EVAP)工作的可靠性和稳定性,很多工程师从电子控制系统和碳罐结构、布置方面来有效减少燃油蒸发排放控制系统的失效。电控方面的改进主要作用是使碳罐电磁阀更适宜的开启和关闭以适应发动机工况;碳罐结构方面改进主要作用是提高碳罐的吸附、脱附能力保证碳罐工作的可靠性,减少因管路堵塞、破裂等因素对燃油蒸发排放控制系统的影响。文章通过对碳罐的空气口结构进行优化,进而提高碳罐的进气质量,保证碳罐工作的可靠性,减少碳罐的维护,延长使用寿命。To improve the reliability and stability of the Evaporative Emission Control System （EVAP）. Many engineers effectively reduce failures of Evaporative Emission Control System from electronic control systems and carbon canister structures and layout. The main improvement of electronic control is to make the canister solenoid valve more suitable for opening and closing to meet the engine conditions; The main improvement of carbon canister structure is to improve the adsorption and desorption capacity of carbon canister, to ensure the reliability of carbon canister operation, and to reduce the influence of the factors such as pipeline blockage and rupture on the evaporative emission control system.In this paper, the air gap structure of carbon canister can be improved to improve the intake quality of carbon canister, to ensure the reliability of carbon canister operation, to reduce the maintenance of carbon canister and to prolong the service life.
