Temperature of 10% distillate for gasoline
Thread Content
The 10% distillation temperature of gasoline reflects the content of its light components; if this temperature is too high, the gasoline has poor cold-start performance and struggles to start in cold weather. However, if it is too low, vapor lock can occur easily in hot weather. The current standards specify that the 10% distillation temperature should not exceed 70°C. So, in practice, are the requirements different in various regions and at different seasons? In places like Hainan and the Northeast, is the distillation temperature of 10% of the gasoline produced different in winter and summer in the Northeast?
10% distillation temperature should not exceed 70°C; the requirements are the same in different regions and seasons. Guangdong and Hainan have specific requirements for vapor pressure, with a standard of 40–65 kPa throughout the year.
Winter and summer are also controlled using vapor pressure indicators.
Control the saturated vapor pressure; originally, we controlled it between 45-55.
It seems to be controlled by vapor pressure
Mainly, the vapor pressure is referenced to adjust the 10% point.
Our original saturated vapor pressure was controlled at 45-55
