Astm D613 Diesel Oil Cetane Rating Analyzer - China

Scope of application

Cetane machine in accordance with ASTM D613, GB/ T386 or

standards fixed ignition lag measured cetane number of diesel

and biodiesel, this product is suitable for nature of sample

with a known ignition diesel cetane standard fuel ( cetane and

heptamethy l nonane mixture at a volume ratio) comparing

ignition properties determined.

specific method is to change

compression ratio of engine Graduated flask, in order to obtain

determined ignition lag ( delay) period, fuel injection start

and combustion ( combustion) time interval between start.

When

sample or standard fuel in combustion process, this time

interval should be fixed at 20 ° ( crank angle of generator

meter) , but different fuel required for combustion of different

compression ratio, which is end of compression stroke,

temperature and pressure are different.

Compression ratio

according to sample gas is not more than five scale readings

select two standard fuel cetane units, obtained in same way to

determine ignition lag.

When sample gas compression ratio scale

reading in one of two standard fuel gas between scale readings,

sample is calculated is designed and made as per interpolation

of cetane number, symbol × ×.

× / CN.

For example 45.6/ CN.

Function characteristics

1, easy to operate.

2, standard oil with less ( measured with ASTM cetane save 50%

or more machine than) .

3, measurement Precision ( compared with ASTM cetane measuring

machine) .

4, to determine conditions faster ( 20- 30 minutes) .

5, measured sample speed.

6, green ( with a unique spray wash exhaust) .

7, low noise ( a muffler tank) .

8, variable compression ratio adjusted freely.

Technical parameters

1, Engine type: single Graduated flask, horizontal, water-

cooled, four- stroke standard hair.

2, Engine Graduated flask diameter ( mm) : 90.

3, Engine Graduated flask stroke ( mm) : 90.

4, Engine piston displacement ( L) : 0.573.

5, Engine Graduated flask compression ratio: 5 to 21.

6, Engine speed: 1000r/ min.

7, Engine Refrigeration mode method: closed water Refrigeration

mode.

8, Engine start- up mode: electric start.

9, Engine lubricants: L- ECC diesel engine oil 20W/ 40 ( GB11122-

89) .

10, Engine rotational direction ( view from flywheel) :

anticlockwise.
