GB 252-2015: Translated English of Chinese Standard

The current [when?] standard for diesel sold in European Union, Iceland, Norway and Switzerland is set in EN 590, with a minimum cetane index of 46 and a minimum cetane number of 51. Premium diesel fuel can have a cetane number as high as 60. High speed diesel engines (as in cars and trucks) virtually all are designed to accept fuels around 50 Cetane Numbers, with higher numbers being a waste. However, Cetane Number is only one important property of diesel fuels, with three of the others being also very important. EPA's heavy-duty diesel fuel analysis program sought to quantify the hydrocarbon, NOx, and PM emission effects of diesel fuel parameters (such as cetane number, aromatics content, and fuel density) on various nonroad and highway heavy-duty diesel engines. Diesel Cetane Index and Number; Ethanol percentage; For State Government regulatory Agencies, pipelines, fuel labs, terminals, research facilities, repair shops, fuel cleaner service providers.

"IF the cetane measured of the two fuels is the cetane INDEX and not the number, then a 50/50 mix of 60 index and 40 index will give you a 50 cetane index. This only works for cetane index, NOT the cetane number of the fuel. The cetane specification per ASTM D-975 is the cetane number." . . 16 Cetane number, cetane index and diesel index Bạn đang xem bản rút gọn của tài liệu.

Diesel engine operation is primarily related to the actual cetane number and the cetane index is simply an estimation of the base (unadditized) cetane number. Industry standards. The industry standards for measuring cetane number are ASTM D613 (ISO 5165) for the CFR engine, D6890 for the IQT, and D7170 for the FIT. See also.

The higher the number, the better the fuel burns within the engine of a vehicle. The cetane number is similar to the octane rating in that it is a rating assigned to a fuel to rate the quality of its combustion.

In Europe, diesel cetane numbers were set at a minimum of 38 in 1994 and 40 in 2000. The current [when?] standard for diesel sold in European Union, Iceland, Norway and Switzerland is set in EN 590, with a minimum cetane index of 46 and a minimum cetane number of 51. Premium diesel fuel can have a cetane number as high as 60. High speed diesel engines (as in cars and trucks) virtually all are designed to accept fuels around 50 Cetane Numbers, with higher numbers being a waste.
