This sounds interesting and will help change the modern diesel engine to comply with EPA without most of the emissions crap.
Worth watching the whole video. https://www.speedofair.com/r-d

Very impressive.
No more expensive DPF's plus increases in economy and torque! |

umm, yeah nah. old low pressure diesel engines had bowls in the pistons to create the swirl required to correctly mix the fuel and get the right overall air/fuel ratio for a clean burn. with HPCR engines the pressure is so much higher, that detailed design of the injector nozzles has significantly more impact on the burn than the piston design.
I don't see any data in the video that substantiates his claim. just pseudo engineering that has no relevence. |

The idea was originally developed for petrol V twin Indian motorbikes but found to be significantly more beneficial for over the road diesels than little diesel cars.

my point exactly. no data on passenger cars. do those big lumbering off road engines even have to meet emissions standards?

CAT pulled out of all on-highway stuff around 2010 or there about because of emissions regulations in heavy vehicles, they do generators and off road stuff now only. |

In the US the most popular OTR diesel still in use in the lower 48 states excluding Commie-fornia is the Cat 3406B using genuine Cat parts still manufactured. This technology is trying to gain certification through SEMA and hopes to meet CARB "Clean Idle" regulations and that's a good thing, despite the negative nelly's.

One question,
the presenter claims that the Exhaust Gas Temperature was lowered by about 200 degrees, so how would that help with meeting emissions, would that prevent SCR converter light off? I’m asking the question because I honestly don’t know….. |

200deg F cooler would otherwise be good for a hill lugging diesel in a unmolested system. The emissions are met completing a cleaner burn so no soot is produced to raise the ex gas in the first place. Unburnt diesel into a hot exhaust pipe creates high temp climbing hills. Looks good rolling the coal but totally unnecessary.

-childly says- is tempting lol
Seriously tho I think the whole video is just a add for the pistons. He mentions near the end that they will also re-flash the ecu and change the turbo and exhaust among other things or was I just hearing things ??

As they state the pistons achieve such a clean burn that there is so little carbon or soot build up to capture in the DPF that it makes it pointless being there.
