For a little while. You have to remember that the very high pressure
jets on the DI injectors blast the fuel mostly sideways; at very
high speed. Depending on the material of the pre-chamber, that
pre-chamber may progressively become eroded and increase in volume
until the engine no longer works.

Spend a bit of money on some books before spending a lot of time
making scrap metal. A couple of reasonable titles from Bosch can be
found at http://www.bentleypublishers.com/bosch/index.htm
Shop around for prices.

"Diesel engine management" in particular
http://www.bentleypublishers.com/product.htm?code=h007
covers many types of systems. 

There's not enough information in the books to build engines and
systems, but there should be enough to understand them.
