Fuel Evaporative Emission Test Procedure To Be Applied To Ordinary-Sized Motor Vehicles, Small-Sized Motor Vehicles, and Mini-Sized Motor Vehicles Fueled by Gasoline (Excluding two-wheeled motor vehicles)
| 1 | Running | The 11-mode running is conducted at a room temperature of 25±5°C. Then, the vehicle is driven by repeating the 10·15-mode running three times. |
| 2 | Measurement (Hot Soak Loss (HSL)) | The mass of hydrocarbons generated inside the SHED for 1 hour is measured at a room temperature of 27±4°C. |
| 3 | Measurement (Diurnal Breathing Loss (DBL)) | The mass of hydrocarbons generated inside the SHED for 24 hours is measured. In this case, the room temperature shall be 20-‹C at the start of the measurement. Then, the temperature is raised to 35-‹C. After a lapse of 24 hours, the temperature shall be returned to 20-‹C. |
