The new BMW 7 series uses direct injection and maybe the new 5 series. Btw what about the use of ski-slope type pistons. They are suposed to create quite a bit of turbulence in order to promote better mixtures. It might work well with direct injection.

Have a look at the Mitis site, they use a ski slope piston with a dish in the middle of one slope. Some very interesting pics as well showing the flame front delevloping during compustion.

yes very interesting info on that site. And i presume this is the piston design you are talking about:

The mitsu engine on that site used a sloped piston I don't know the deffanition of a ski sloped piston but it was pretty sharply sloped, just like a 2 stroke piston. In addition to better atomazation of the fuel a sloped piston seemes to have a much better squash effect which while not the best idea for thermal efficency cuts down on knocking (squash effect moves air in a current that prevents any fuel molecule from staying in contact with the hotspots for any dangerous amount of time durring compression) But if my idea is correct knocking will not be a problem for DPFI anyway, you cannot detonate what is not there. Does anyone make a forced induction DPFI???? |

well modern turbo diesels use that. I do not know of any gasoline engine though with DPFI and FI.
