Basic Information of Gasoline Products               Basic Information of Diesel Products
Gasoline is a special fuel applied in combustive engines. It is generally water-white transparent in nature with the density between 0.71-0.75g/cm3 and a unique aromatic smell. It can be divided into aviation gasoline and automotive gasoline; automotive gasoline and automotive ethanol gasoline (E10) are sold in service stations. The current specification for automotive gasoline products is GB 17930 “Automotive Gasoline” under which there are 90#, 93# and 97# gasoline; and the current specification for automotive ethanol gasoline (E10) is GB 18351 “automotive ethanol gasoline (E10)” under which there are 90#, 93# and 97# gasoline. The specification of 98# gasoline is in line with enterprise specification. The automotive gasoline and automotive ethanol gasoline (E10) are categorized in accordance with Research Octane Number (RON).
 
Gasoline Performance Needed for Automotives:
1. Anti-explosion
2. Evaporation
3. Anti-dioxide and Stabilization
4. Anti-corrosion and environmental requirement
 
Items to be examined in terms of gasoline quality are as follows:
Anti-explosion performance (research method octane number,motor method octane number, anti-explosion exponent), sulfur content, steam pressure, olefin, aromatics, phenol content, corruption and distillation range, etc.
 
How to choose gasoline:
Gasoline octane number is supposed to be compatible with the compression ratio of the engine. If the engine with high compression ratio is applied with low octane number gasoline, the engine tends to knock, which will cause malfunctions like piston sintering and piston ring breakage and impairment to engine parts. If engines with low compression ratio is applied with high octane number gasoline, the ignition timing will be altered, which will cause incremental sedimentation inside the engine cylinder thus shortening engine life. Gasoline numbers recommended by China Automobile Industry Society and China Environmental Protection Industry Society for domestic and foreign brand cars are listed in the form below:

Basic Information of Diesel Products                     Basic Information of Gasoline Products
Diesel is a special fuel for compression ignition engine (i.e. diesel engine). Diesel, appearing water-white, light yellow or dark brown, is divided into ordinary and automotive diesel. Ordinary diesel is used in the compression-ignition engines such as tractors, internal-combustion locomotives, engineering machinery, ships and generating sets, and in the three-wheeled motorcars and low-speed trucks specified in GB19756; automotive diesel is used in the compression-ignition engines except the engines mentioned above. Diesels sold in service stations are automotive diesels or ordinary diesels. The current specification for ordinary diesel is GB 252-2011 “Ordinary Diesel” under which there are 10#, 5#, 0#, -10#, -20#, -35#, and -50# diesel; the current specification for automotive diesel is GB 19147-2009 “Automotive Diesel” under which there are 5#, 0#, -10#, -20#, -35#, -50# diesel. Ordinary diesel and automotive diesel are categorized according to the freezing point of diesel.

Requirements on Light Diesels for Diesel Engine
Due to the fundamental difference between working process of diesel engines and gasoline engines, the quality requirement for diesel is different from that of gasoline as well, specifically:
1.  Good combustibility
2.  Good low-temperature mobility
3.  Appropriate evaporation
4.  Good stability
5.  Appropriate viscosity
6.  Good anti-corruption performance
Items to be examined in terms of diesel quality are as follows:
Cetane number, oxidization stability, sulfur content, color, acidity, ash, copper sheet corrosion, solidifying point, cold filter plugging point, flash point and distillation range, etc .

How to Choose Light Diesel
The following principles need to be followed in selecting diesels according to requirements of the GB 252 and GB 19147 specifications:
1. 10# light diesel is compatible in diesel engines with preheating units;
2. 5# light diesel is applicable in areas where the risk possibility is 10% and the lowest temperature is above 8→;
3. 0# light diesel can be applied in areas where the risk possibility is 10% and the lowest temperature is above 4→;
4. -10# light diesel is applicable in areas where the risk possibility is 10% and the lowest temperature is above -5→;
5. -20# light diesel can be applied in areas where the risk possibility is 10% and the lowest temperature is above -14→;
6. -35# light diesel can be applied in areas where the risk possibility is 10% and the lowest temperature is above -29→;
7. -50# light diesel can be applied in areas where the risk possibility is 10% and the lowest temperature is above -44→;
