im aware, just pointing out how a conglomerate like bosch can be petty. so no doubt the others are like this too
Not sure there is a patent on dimpling anything. Maybe the specific pattern Shysters of Air use is patented, but not the general concept.

Let's not forget that there's a whole world of diesel engines outside of passenger vehicles. Even if there was some big strange conspiracy to keep these miracle pistons out of passenger cars, industry as a whole would jump all over an 8%, 20%, 50% whatever increase in fuel efficiency.

Doesn't sound any quieter than what's normal. The skinny old white guy with the beard was going on and on about how quiet those pistons made a diesel in an earlier video.
The EA288 has fairly low compression already, that and the two pilot injections makes a very quiet operation. I wonder how much compression drop there is with the dimpling.

I think the car is deleted, not sure if straight pipe or to muffler. But at idle it sounds to me like a non deleted engine.

I will consider these kinds of things when they arrive in production vehicles. I see ads all the time on new miracle engines and such. For the most part you never see them make it to a production vehicle. Fun to read about but have little expectation they will ever make it into a vehicle that is mass produced and out for sale.
