SECONDARY AIR SUPPLY SYSTEMPROBLEM TO BE SOLVED: To restrain a backflow of exhaust gas of an internal combustion engine into a pump for supplying secondary air.ITO KAZUHIRO伊藤 和浩
The secondary air injection pump injects fresh air into the exhaust stream to help burn off harmful pollutants in the catalytic converter. If the injection pump begins to fail, since it is a vital part of the emissions system, a fault code will be triggered. Sometimes, when pulling off the...
Variable primary flow system is the newest system of center air-conditioning systems,which has large advantages in first-cost and operational cost than primary/secondary systems. 一次泵变流量VPF(variable primary flow)系统是中央空调系统的最新布置形式,与一二次泵系统相比在初投资和运行费用上更具有优势...
摘要: PURPOSE: To eliminate the necessity of making a motor-driven air pump large- sized by supplying secondary air even in the normal operating condition such as the decelerating time besides the warming-up of a catalyst at the starting time of an engine....
