Genius the donger is 2 hours ahead of you I'm 14 hours ahead of you. The donger sells used cars, I install, upkeep and repair marine diesels. But the real funny thing is every minute you live has already been used by me and also the donger not to mention a few million asians and europeans:evilb::evilb::evilb:

Lets then say I´m a pessimist until I see something new and not IMO borrowed.

Regarding Alublocks. Thats nothing new and not is iron sleeving a alublock either.
Not even a alublock with wet liners or a wet monoblock.
All that has been around over 50yrs.
The last new thing for diesels has been the commonrail and even that patent is more than a 15 yrs old Alfa-Romeo patent sold to Bosch.
Now if Alfa Romeo would get their head in making a high perf diesel...well that would be something.
That would meen Alfa get´s free hands on the project from the main owner.
I mean there´s a companyh who has a reputation of doing everything in overkill when you don´t hold the engineers back a little...
Crazy Race-engineers there tied to do ordinary jobs...

How do one get 750 out of the Audi V12 diesel ?
By throwing the catalysator (particulate filter) and Restrictors away and turn down it 250+hp from what it´s capable of.
Still it weighs the same as a Mercruiser 1075/1200 and is a bit SHORTER ( the same as a SBC +.4 inch) but destroys SSM6´s for breakfast.:evilb:

When do one get hands on a V12 Tdi..hopefully someday...
We didn´t get the FIA GT3 Audi R8 racecar either for 2009 but maybe 2010.

Thanks for sticking up for me 40, but I do see where they are coming from on some of it. Just like everyone else we talk to, no one wants to believe we can do this because it is new. Most people are afraid of change.

I've been here since June of '07. The project has been going on since Spring of '03.

Timbillyosu,

Thanks for taking your shots at me, I deserve it. I for one don't think the reasons you can't do this is because it is new or I'm afraid of change - I never said you can't do it. If you read anything on here about me or ask anyone here that knew me back when - I am not afraid of change, I pushed for change.

When you make statements like this:

"We had it running the other day for about an hour at around 2000 rpm without any problems. We need to do a little more work to get our dyno fully-functional but things are going good."

I have to question the project, you say your at this for 6 years now and the dyno's not fully functional, you need to raise capital and after that it's another 2 years, so of course we're skeptical. We all dream and unfortunatly most dreams don't materialize the way we planned.

Since all your doing is talking which I do lots of myself, I appologize for taking it more serious than you intended for it to be.

I wish you luck and keep us informed and I'll be quite (but only about this one - LOL).

ps I understand what BSFC is I thought maybe others don't know what 0.35 represents and lbs/Hp Hr just puts it into a user freindly representation.

enough, not another word!!!

Joe, I did not mean for you to be silent, I do appreciate the criticism. And looking back on it, you are right.

The dyno thing was actually caused by a lightning strike. It had fried the connectors and we didn't realize it until we were trying to run things ( the dyno had sat unused for a while since we were focused on machining and such)

Skepticism is something we've come to accept (and partially thrive on). In the time that I've been here, we have made leaps and bounds of progress. I feel I didn't fully explain the timeline that we were on when I said 6 years.

My boss, Mike Buck, started a project to improve other engines 6 years ago. He had originally planned to update New Holland tractor engines. He worked on this for about 3 years but then was finally unable to get a deal struck with New Holland to provide just the components we needed (they wanted to sell us entire engines). So he took what he learned from modifying the New Holland engines and set about designing his own.

After a year or so of R&D work and filing patents, we begin machining components to create this new "Buck Marine Diesel" engine. In the past 2 years, we have gone from the design concept to a running engine. There are still some tweaks and improvements that need to be made here and there, but we feel that the overall design is solid.

I hope this clears things up a lot better than I did before :)

Please keep the questions (and criticism :)) coming!!!!!

Your in NC, right?

End of March we start fishing in Nags Head again, I'll come and visit you guys!!!!

One serious question, what market are you trying to go after?

You made reference to making a "performance" product or is that just and after thought since you guys think there might be some kind of niche there?

One tech question, what are you doing for pistions? All alum, steel tops, steel buttons.

Do they have an oil channel in the piston or just splash from the nozzles?

Thanks,
Joe Gere

Don't forget ALL STEEL!:drink:

Days for those are gone unless you use heavy heating oil, preheated...and no more than 400 rpm...:eek:

We'd LOVE to have you stop by. We're about 2 and a half hours from Nags Head.

We don't really have a specific market. This engine can be configured in several different ways making it pretty versatile. Virtually any boat that requires a diesel engine between 150 and 650 hp could be our potential market I suppose.

The pistons are Alum with steel grooves for the rings.

The oiling of the cylinder is confidential for now. We are developing a new type of process for that which I cannot divulge at this time.

timbillyosu,

Look at how Mahle cools their psitons, it very cool and eliminates the buttons we used on high horse Cummins.

Just a thought?

Both Caterpillar & Komatsu have high speed diesels with one piece steel pistons:drink:

Don't forget Komatsu's piston cooling system. The oil jet hits a port on the underside of the piston and the oil is run through a cooling circuit in the head of the piston:drink:

Firefox,

That's the Mahle piston, that system was engineered many moons ago but still can't be beaten! Very expensive psiton though?

Expensive but worth it. The steel versions that Komatsu uses usually out last 3 or 4 sets of liners:drink:

Hey all, sorry it has been a little while since I've posted. I've got a new clip of our engine. Check it out:

Cylinder Tear Down and Rebuild

In this video, we take a running engine, shut it down and tear down a single cylinder to the bare crankshaft, rebuild it, and start the engine back up. All in less than 8 minutes!

Don't believe me? Watch it :-)

Let me know if you have any questions.

Cool ! Good luck on what appears to be a trick package.

That's Great , What Kind Of Hp Are You Making ?
How Much Does It Weigh ?

Thank's
Mike

Very interesting. Keep up the good work.

Hp numbers aren't quite where we want them yet. We're still doing a little tweaking and changing. We are shooting for 700 hp or so.

The engine with fluids, ready to run, weighs about 1500 lbs.

Please post the dimensions and exact weight for this new diesel as well as the horspower and torque curves so we performance boaters can evaluate its potential uses.
It would also be nice to have an approximate price in lets say a 500-600HP range. If its going to be a success, you've got to start with some specs and prices so repowers and builders can work it into their plans.

Best Regards,
Ray @ Raylar

Ray..weight is on prev. post..appr.1500 lbs with fluids ready to run..HP is at 650@3000 rpms..and the rest of the info can be found here..

Thanks Jassman.

I also need to point out that these engines are not yet commercially available. We are still working to secure funding to go into full-scale production.

We have the potential to revolutionize the marine diesel industry and create about 200 American jobs, but we can't seem to find the capital to move forward.

SOUNDS LIKE YOU NEED AN INVESTER .
START A THREAD ,YOU NEVER KNOW WHO IS ON THE BOARD . THERE ARE SOME VERY WEALTHY PEEP'S ON THIS SITE THAT MITE WANT TO INVEST .

No problem..here's a thought..get a few of your motors in some boats..dial them in and let these guys attend a few poker runs..Diesels have there place in this market..I had 2 yanmar's in a 43 Nortech..liked everything about the boat and motors..except the top end number..now with 650hp vs the 480 that I had..the top end number would have been better. The problem will be getting the name out there..vs the Yanmar or Cummins which have proven themselves..but hey..they had to start from somewhere as well..I wish you guys good luck..and hopefully being the first to get your product to the table..Jeff

1,138 lbs of torque at 3K rpm. That is not bad. The Cummins QSB11 has 1,050 lbs of torque so this is a good start.

Good advice as always. :)

This^^^^

That is definitely something that we are looking to do. Unfortunately, as I said, we need capital to do so. We are planning right now on having about 25 test boats. Just let a few people take these things out and hammer on them for a while and see what happens. :)

That's not a bad idea... I think I'll give that a try :)

Wish I had the type of boat to put them in, I have time and don't mind beating on stuff I don't have to fix.:evilb:

Has the engine gone thru any EPA emissions varifiaction testing? Did it pass, what tier rating did it get varitied at? If not that could be your biggest hurdle. I wish you the best of luck with your engines, they do look very interesting.

We haven't done any emissions testing yet. We're working on getting everything running the way we want it to before we do any emissions or longevity testing.

Are you running a bosch controller for the injection? Variable geometry turbo or single stage turbo? EGR?

The ECM that we are running right now is a custom program. We have the engine hooked to a laptop that we use to control the injection timing, injector pulse width, and pump duty cycle.

Right now it is a single-stage turbo. We are looking at VGTs for the future.

No EGR.

Interesting. Thanks for the info! Good luck with your testing.

I know in pickups and OTR trucks, emissions is whats killing them.

I think what your doing is a good idea. If I had a boat, Id let you put these engines in so i could beat on them and let you guys fix it.:evilb:
