Chinese Injectors Testing
Posted: Sun May 04, 2014 10:18 am
Ive seen this come up in various places, so thought at $10 each off aliexpress id buy a couple and test them. I chose one that looked genuine, but alas they just use genuine photos to get the sale, most of the forums i had read also said these didn't pass @ 70psi line pressure like the genuine bosch's would.
These were ment to be 0280156280 which are 42LB @ 51psi or 3.5bar
I tested the 3 of them @ 51psi, 13.8volts, 6000rpm @ 8ms for the first row and 2500rpm @ 3ms for the second, as you can see no hope in hell of getting a matched pair there. Also of note the spray patterns were all different.
CC/Min
1 348.23 52.64
2 361.14 56.55
3 383.45 66.97
Deadtime @ 13.8volts
1 0.56
2 0.51
3 0.48
Deadtimes nothing good there.
Testing @ 100% DC
51PSI 77.71G/15s 41.11LB/Hr
70PSI 89.20G/15s 47.19LB/Hr
So these did work @ 70psi.
Overall you get what you pay for lol
