るものでなければならない。For example, the exhaust gas emitted from the engine of the UDJ East contains carbon oxide and components that are harmful to humans, so this exhaust gas is emitted before being discharged to the outside. These components must then be removed by re-burning some of them in the engine. At this time, a device is required to recirculate the exhaust gas into the engine, but this device must be able to recirculate the exhaust gas according to the engine's intake negative pressure. No.
