Question
We have a generator set model VTA 28-G2 ( timing code R ). After we
replace fuel injectors and adjust valve lash ,the engine has too much white smoke when running at 750 rpm .
Please help me what's about this case.
                             Thanks.

Answer
I have sent an answer on this question before, I don't know if you received it.
However, you should know that with genset engines, it is common to have bluish white smoke when running below rated speed of 1500 r.p.m.
my advise is that you should bring the speed up to 1500 r.p.m and add some load up to 3o% of maximum load for about 15 minutes.
If the smoke continues, then you need to recheck your injector travel and valve lash adjustment.
You can carry out temperature check on each cylinder to be sure of the injector that is causing the problem.
