Set 8 • Question #348 of 382
Launch Interactive Practice Room In comparison to straight flow mechanical atomizers, return flow atomizers provide relatively uniform atomization over a wide firing range due to the __________.
A
back pressure regulation resulting in more complete combustion at high firing rates
B
oil supply pressure not having to be reduced at low loads to the point where poor atomization occurs
✓ Correct Answer
C
return flow atomizer being designed for best combustion at low firing rates
D
rotational motion imparted by the tangential slots being greater in the return flow atomizer
USCG NMC Regulatory Explanation
In USCG Motor Plants (Diesel Engineering), regarding 'In comparison to straight flow mechanical atomizers, return flow atomizers provide relatively uniform atomization over a wide firing range due to the', the correct operational principle is: 'oil supply pressure not having to be reduced at low loads to the point where poor atomization occurs'.
