I've been curious about diesel piston geometry, particularly how it relates to performance, for many years but no one really talks about it in this detail and it's very hard to find cut and dry information. White papers can be a bit hard to digest sometimes... Please keep this type of content coming!
It would be fun too see what he may know or can share some of: flame speed vs bsfc ratio in Diesel engines. I would assume/believe the oem’s already know the answer to this but without being a oem and using studies that are publicly available feel that I can with a fair amount of accuracy predict at what brake specific the flame speed will go sonic which follows what has been already proven and visually captured in pro mod spark ignition motors. There is one photo taken by Jason sands of a diesel that matches the same photo shown in a Darin Morgan video on air speed with his example being a pro mod car of shock cones exiting the exhaust with after words proof of a now damaged engine. This may match up with: clean burn under load producing high hp (low brake specific fuel consumption ratio) setups in diesel drag racing are showing higher failure rates at lower power levels then their sled pull cousins which due to rules, make getting higher flame speeds and bsfc ratios as low much more difficult all the while still producing a average produced hp per second without a component failure still higher. Watching dyno pulls chassis and engine the motors that look to run a exhaust opacity of just a slight amount of haze comparable to a stock 12v truck when you mash the throttle vs the motors that are running 100% clean. The ones producing just a hint of haze at the same power level appear to survive in a competition environment at a higher rate then the ones run completely clean. I lot to look at but it’s something I personally have not gotten to ask someone who may know the answer of or point in the direction of where to look. This guest who works in the oem may be a good one to ask haha. Thank you for the awesome videos and great products.
Thanks for watching! Send over your questions to marketing@dynomitediesel.com, and maybe we'll have him back for a follow up, and to answer some of these questions!
Cam shaft EGR. Can you do a vid explaining this effect, and the pros and cons with vs without. What cam shaft would delete it and if its even beneficial. A google search resulted in limited info on this. You guys seem to know your stuff. I am wondering if changing a cam shaft would improve fuel efficiency on 750hp and up builds. I would love a detailed dive into this topic from someone with a ton of knowledge in this field.
Very informative as all your videos are. Incredible topics that mean the world to the industry. Anxious to see what part 2 brings!! Always important to see how and why the industry changes.
Very cool conversation. Piston design has come along way. One product I hope gets discussed in part two is the steel piston. Also, do you think Volvo's wave piston design in the d13 engines will ever make it into OEM passenger vehicle engines? Love the content!

This is an awesome video to have out for the general diesel community
Lots of very good info in this
Much appreciated
Thanks for watching, we appreciate it!
There are 3 more parts coming next week!
Aswome content thanks for sharing

Hamilton and Colt both make ones that eliminate it. Getting ready to replace the one in my 06.
Fuel efficiency and higher HP numbers typically don't tend to mix very well. Maybe we'll do a video on cylinder scavenging in the future!

Glad you enjoyed it, Thanks for watching!
Always putting out great content thanks Lenny and crew.
Thanks, we appreciate it!
Part 2 drops Monday, as well as the other 2 parts later in the week!

@@DynomiteDieselTV looking forward to it. Love this style of format...wonder if you guest could do an interview on the diesel podcast too?
He probably would, if he was asked/invited.
👍💪
