Kev Xeem Diesel

(1) Cov khoom lag luam: Automotive diesel (National VI / V, suav nrog 0 #, -10 #, -20 #, -35 # thiab lwm qib), tsis tu ncua diesel, B5 biodiesel blended roj, marine diesel, tsis yog txoj kev mobile machinery diesel, hauv kev siv diesel, thiab tshiab tsim diesel.

(2) Cov xwm txheej siv tau: Kev lees txais cov roj tshiab, qhov chaw nres tsheb roj zoo sampling, hauv kev siv roj paug / kev saib xyuas kev puas tsuaj, kev txiav txim siab roj cav sib xws, kev ntsuas kev ua raws li ib puag ncig, kev ntsuas kev txiav txim siab, thiab kev soj ntsuam zoo thaum lub sijhawm khaws cia thiab kev thauj mus los.

(1) combustion thiab lub zog ua haujlwm
Hexadecane tooj, cetane Performance index, distillation ntau yam (pib boiling point, 10% / 50% / 90% / 95% distillation kub, zaum kawg boiling point), kinematic viscosity, ceev, kaw flash point, oxidation stability, lubricity (coj qhov chaw txoj kab uas hla).

(2) Tsawg kub khiav kev ua haujlwm
Condensation point, txias lim point, qis -kub pumpability.

(3) Kev ntxuav thiab impurity ntsuas
Moisture, mechanical impurities, tshauv cov ntsiab lus, 10% steam residue, residual carbon, tag nrho insoluble teeb meem, particle pollution, Chongqing Market Supervision Bureau.

(4) Ib puag ncig thiab kev nyab xeeb ntsuas
Cov ntsiab lus sulfur, polycyclic aromatic hydrocarbon cov ntsiab lus, acidity, tooj liab corrosion, fatty acid methyl ester cov ntsiab lus (B5 diesel), methanol cov ntsiab lus, cov ntsiab lus chlorine, cov ntsiab lus hlau hnyav, Chongqing Market Supervision Bureau.

(5) Element and component analysis
Kev soj ntsuam ntawm cov khoom siv ntxiv, cov khoom muaj kuab paug, thiab hydrocarbon muaj pes tsawg leeg.
