It’s pretty safe to say, if one change in an engine, It will cause changes elsewhere

Good point, ceramic is tough as nails when it comes to heat but can also be brittle on impact. My thought is, what if I creep into detonation territory and get a very slight ping, does that piston top shatter? What about full on detonation? I've had a motor detonate and shatter the front and rear-center plugs in a v6 Gas engine and the engine still runs and drives fine but isn't as smooth at idle. The detonation wasn't that bad internally, no boost, lower RPM, when it happened. Was something with the coil pack or plug dropping out at around 90% throttle pulling from a dead stop. The takeaway is the fact it shattered the plugs and even cracked others around the center plugs, the ceramic on the plugs.

In my 19 years of automotive powertrain testing experience, this appears to be a good product idea but is giving me a little too good to be true vibe and another "re-inventing of the wheel". I'm not opposed to seeing more on this but I find it hard to believe timing events haven't been changed as well as the amount of injections per cycle since both of these things have a huge effect on diesels combustion noise. As good as it is being sold, it makes you wonder why this concept hasnt been being utilized by cummins.

As a physicist, 13 to 16 mpg seems unreasonable. In the end, efficiency is physics and the only way you increase efficiency of the diesel cycle is by increasing compression ratio, increasing temp, and decreasing the temp sink. Their pistons might provide a higher compression ratio. The ceramic top might reduce heat loss (higher temp), and the heat sink (atmosphere) is going to be the same. I’m not sure you can get 20% more efficiency from these changes, and then add in environmental emissions considerations, and that makes me more skeptical. Maybe, but this definitely falls into the “show me” category.

Having worked with some of these changes myself, I am impressed. It took weeks to get the plating and modifications done. Sending pistons among several shops. And no dimples! These pistons bring several factors together. Ultimately it’s quicker and likely cheaper to run with these pistons. Ring blow by has been a source of soot loading in the oil. It shortens the life of your oil. Keeping the soot and stray idle fuel wash out from getting in your oil is worthwhile!!!! Based on my experience, I am definitely going with these pistons in my next 5.9 build..

We tested this on a wet flow bench. So we took 318 heads one we put HUGE dimples into combustion chamber, one we roughed up 40grit, and one we polished. The wet flow showed the dimples and rough surface worked well to stop pooling of fuel. With polished HORRID combustion chamber of 318s it puddled on head didnt get complete "burn" or atomization AT ALL. So there is some truth to this in keeping fuel in air. Direct inj fixes that obviously. But im interested in what benefits on head of piston would be. Our dimples where much more close to each other. But it did work. Wow the noise is way reduced

Then you pull the engine change the pistons and repeat all the tests.

From what I've seen\heard\watched they seem to be a very dramatic change in something like a piston thats been pretty much the same for decades if not a century or more. Adding the dimples has shown increased MPG in various vehicles of 10, 15, 20% depending on what else is going on. Thats alot of increase when your talking about a OTR semi truck going back & forth across the country every week of the year. It's like a really good increase in the combustion cylinder leaving less un-burned fuel, & overall just a cleaner exhaust coming out of the pipe\stacks. Who woulda thought golf ball dimple technology would make it into the internal combustion engine on piston faces? No one! It is crazy to see improvements like this after being the same for so long! Id put these in my 7.3 in a second....if i ever had to rebuild it cause it died, cause it probably won't.

Awesome videos Mr Dave, I wish that your shop was down the street from me, here in southern California outside of Los Angeles. I would totally trust you to repair anything on my vehicles, I'm a plumber by trade but I have been doing auto repair work myself. I have a 68' Ford Rachero that needs engine and transmission repair, I'm hoping to retire soon so i can actually focus on my project. Keep putting out those excellent videos!

Speed of Air technology is something new, I’ve asked if they would make piston’s for my old 7.3 but they have no plans, they make the pistons for 6.0 liter Cummins and Cat.

Yea that would be fantastic but unfortunately not as many of us with the ol 7.3 anymore to perk these guys up. Just imagine how weird it would sound with the injectors still hammering.
@bondobilly936910 ай бұрын
The cummins 5.9/6.7, cat are the bigger demand for now, so they'll focus their energy there and as demand and money comes in, expand to older engines

Looks and sounds like a winner Dave, I have worked diesel service and repair for all of my life but never knew this type of piston was available. I remember when Slick 50 came out and it was awesome to quiet down a Diesel engine. Wynn oil for transmissions, Minneapolis Moline G1000 had this howling noise that would make you deaf. Keep up the great work.

Love your channel Dave. Just curious the cost of this If I had a duramax let’s say w 50k and I wanted these pistons. Thats a big overhaul. Or let’s say I had a fleet of 30? 30 motors at your rebuild price ? That’s a lot of diesel fuel. Is the juice worth the squeeze. I do love the concept

Going from 13mpg to 16mpg = $576 per 10k mi at $4 a gallon ( UT, salt lake basin price as of 3/11/24) . This yealds a 9month ROI for my 25k per year based on, The Diesel Podcast, speed of Air interview price point of $1025 for cummins 5.9. Less if you discount the price of stock replacement slugs.
@NA-oq4ty10 ай бұрын
If I was to guess how the dimpling would affect the engine performance, it would be more efficient, air flow and maybe cleaner, scavenging and a reduction and nock.However I do for see the possibility of engine overheat if the engine's cooling system is not beefed up. The reason being the edges of the dimples would serve as points of heat collection and that could cause a spike in temperatures that could radiate down into the metal of the piston, causing eventual piston failure.This is all just spit bowling on my part.I haven't got any degrees.I haven't done that a testing.I'm kind of interested to see where this goes to.

The types of technologies employed here are not new although the ways in that they are used together to achieve their end result is pretty genius. It's a simple process really, the science of it makes sense and so does the logic. I believe everything that they claim these pistons do with the exception of the EGT drop of around 200 degrees, I really need to see the tests and results from several engines to be completely convinced. I'm not doubting it completely as I'm sure there is a decent drop in the EGT I just find it hard to believe it's that much though. Another great video! Thanks Dave. I'll bet there pistons will be amazing in your Monster blocks.

200 degrees less on exhaust gas temperature means your DPF is going to fill faster (because it's not passively burning off like it does at 600+ degrees fahrenheit). Perhaps reduced soot would make up for that?

I’ve used gapless rings from total seal in many of my race engines….they do work…. In fact one engine in particular comes to mind……a Hot SBF stroker engine was built with conventional style rings…(good rings) After just a few thousand miles an oil residue was noticed in the throttle body from the crankcase vent return….engine ran great with Great compression and didn’t burn oil….that winter the engine was pulled and a few things were done to it ….total seal gapless rings was one of them…for the next 2 seasons of drag racing and street driving there wasn’t any oil residue in the throttle body…engine ran better than ever and picked up almost half a sec in the quarter…(big gains in the drag race world) not sure how much the rings helped with power but I’m sure they did help.

I'm pretty sure hotrodder and HotRod Magazine tech editor Jim McFarland patented the piston dimples about 30 years ago. Dimples have been quite ridiculed much like the Singh Grooves... But done properly they do improve combustion. Interestingly some of the Engine Masters guys have used both of them, as well as numerous race engine builders. The name of the game is RESULTS !!!
