Toyota /Nippondenso's approach to HPFP pump design.

The Nippon Denso approach can do much less volume, harder to add capacity vs. the CP4 (which can just add cylinders.

Much more expensive to manufacture.

Good only to 1,800 bar (a lot less for the higher volume models).

But it is much easier to design hydrodynamically.

Would like to see what coatings it has.


How is it lubricated? Is it fuel in the whole thing, or is it lubricating oil on the outside loop? The photo suggest it is fuel lubricated.


Note it is paired with solenoid injectors that are probably much slower than the piezo electrics:
