What causes the pumps dc to increase, physically?

The IPR closes some more.

over 65% DC is not good.. poor maintenance and a long hard life can cause pump failure.. large injectors that love oil can also raise duty cycle... that's why we love hybrids so much...

Interesting. What's your idea of a hybrid?
