Engine Concepts...

I have over an entire case of 60 watt lightbulbs you can have if you drive over and pick them up. I find no difference in the light output of the CREE LED's and incandescants, it's the same color same brightness etc, but see a huge difference in my electric bill. The electric bill at my house with 1700 sq foot under air, and 2100 sq ft with 2 car garage and laundry room, with the a/c set at 76F 24/7 averages $135 a month including doing 4 loads of laundry per week, cooking with all electric appliances, using the dishwasher 2x a week, have 2 outside lightbulbs on all night etc......etc.....and I don't have to change a burned out lightbulb somewhere in the house every 2 weeks anymore either......This is in Pompano Beach, FL where it was 93F today for example.

Perfect example. I have 2 60 watt equivalent CFL's (8.5 watts) on all night outside 10 hours= 170 watts per night, having 2 incandescants would be 1200 watts per night........huge difference......

Hi,

Was it painful to write that?

Hi,

Put a couple in your own or a family members boat and run it around the shows, if they are as good as you say word will soon get out.

Concepts

You guys are a tough audience. I don't think I have ever seen so many half empty glasses. Modular air cooled engines have been around for 100 years and most are well respected. The Deutz air cooled is lauded as one of the best ever built. Why not a modular water cooled wet sleeve engine. I have crawled around in my share of engine rooms as well and that is the reason for the design. Another primary reason is for better cooling. No Siamese cylinder engine will ever cool as well as a modular water cooled engine. Front to back series cooling never will never work as well as individual cylinder parallel cooling. If we can all agree that heat is what damages engines, then it stands to reason that an engine that runs cooler will most likely last longer. The idea is not to build a quick repair engine and design it to run on the edge so that it needs more repairs, but to build it for longevity and when it needs repair, and all engines eventually will, that the repairs can be made in those tight spaces more easily. My experience is that most problems with recreational engines come from poor service or lack of preventive maintenance. A simple raw water pump impeller failure can cause huge damage, with a less than knowledgeable boater at the helm. Now if you are an engine dealer that survives on service hours, you most likely won't like this. A forty hour rebuild turns into a 4 hour rebuild. A single cylinder damage goes from 20 hours to 20 minutes. It doesn't matter if it takes 8 minutes or 80 minutes to change a complete cylinder, it is still faster and simpler with the modular design than with all the rest. If this ever sees the market light, the end user will like this, the service dealer, not so much. By the way. All the gaskets are O-rings and copper rings. No flat gaskets at all. No gasket surfaces to clean at all. A 15 liter diesel gasket set fits in a ziplock sandwich bag. Easy to ship and easy to store.

Hi,

There are a few of us here that hold Chiefs Tickets and are not spring chickens who have seen glasses in all conditions.

The internet is a wonderful place just as long as everyone remembers it is easy to sit behind a keyboard and ,massage things till they look good. The Govt of all countries employs them, they are known as statisticians


No too good to be true earth shattering discovery should be accepted as being an actual fact when taken at first glance on the net.

Just curious, why have you never installed a test engine?

J, you need to get more up to speed on the market. There are CAT 3500 (8/12/16 cylinders) installations in plenty of motoryachts in the Westport class built globally. A Westport type MY is a semi-displacement vessel. The 16V2000 is rated at 2600hp not 2400hp. There are 8/12 cylinder MTU series 4000 engines that bridge the power gap you are talking about and CAT C32's are in fact installed in large SF's (over 80') and MY's above 100'.

CAT/Cummins/MTU all chase the high speed Offshore Crewboat market as well that starts at 150'+.

Maybe you want to high light instead the fact that modern diesels of 2.2 - 2.6 liters per cylinder are peaking at about 162.5hp/cylinder. If you are looking for 3800hp in a 16V2000 that is a power increase of 75hp/cylinder or a 46% increase. In todays emissions driven market, good luck with that.

Insulting the people who are most likely to be your customers or who will guide the owner on machinery purchases isn't a very good way to promote your product. The members here have been remarkably reserved and polite so far but if you are going to insult us then your idea to promote your engine to what is probably the largest and most experienced group of yachting professionals on the net is probably not going to be very satisfying.

Rather than insult your audience how about just publish the data you have collected in your test cell over the past 5 years.

The reason you have lost credibility here is because you came in with BSFC numbers that defy belief because they exceed any engine in its class, and you could not or would not support any claim with data.

At least one engine that you claim to be a runner has evidently been sitting in a test cell for 5 years, surely you have collected some kind of data other than the time required for a couple of guys to pull a cylinder and piston.

Even that video is suspect. It appears that no coolant was drained or replaced and as far as running is concerned, a sound track doesn't mean the engine was running before or after. Your mechanics must have thick skin, they didn't appear to have any problem handling parts that should have been fairly warm. It is strange that the video never showed the piston crown or the head and no oil was visible on anything.

Modular marine diesels are pretty common these days so you haven't actually broken new ground in that area.

My take on tough audiences:

Sales and Marketing - glass is half full, we can sell anything
Engineering - glass is half empty, prove it to me first
R&D - glass is half empty, let me test it some more
Controlling and Finance - glass is half empty, guarantee my ROI
Board of directors - glass is half full, but your job is on the line if the numbers don't come through

To have a successful product launch, you will have to pass through all their gates.

Unfortunately it's your glass that isn't even 5% full and you're trying to sell us on. You're not Carbonaro. You can't put an empty glass on the counter and then convince us it's full of fine champagne.

We all come from different directions. K1W1 and Marmot as engineers. Others as captains. I come as both a businessman who is his career was involved in many acquisitions and new product launches. In that respect I would show you the door quickly. I also come as a boat owner and purchaser. In that respect, you'd got nothing at this point that interests me in the least.

You've never contributed anything to this forum but then come and post on this product and when you don't get praised and told how wonderful your concept is, then you attack those who respond. You didn't buy advertising and earn the right to have a pretty photo on the side where no one could criticize. No, you posted your pitch in discussion threads and then when the discussion doesn't go your way you then decide to criticize your audience. That's the thing of failed comedians. The audience doesn't laugh and even boos so they turn and start calling the audience members names. In five years you show no progress. I expect the same the next five years. If you want to change the criticism, then actually do something rather than just talk about it. Meanwhile your boss will continue to run his two CATS, and the others of us will continue with our existing engines. We'll both be happy and not longing at all for your product.

In December of 2007 we cranked the first prototype (the one in the videos). The next obvious step was to place engines in boats. I had a 43 Viking express with 6V92 TAs (the market really needs a good replacement for this engine) that I had purchased in 2006 for that express purpose. Then 2008 and 2009 happened. I had been self employed for almost 40 years and had never had banking issues. In 2008 all that changed. I was heavily into real estate and all the values were cut in half or worse. All of the offers that I had in 2007, to fund the commercialization, disappeared. My banking agreements all folded.

After scrambling to salvage what I could, there was nothing left to go forward on. The progression plan was sound but 2008 changed everything. My brother with his PHD in finance couldn't figure it out. Since 2008 I have continued to refine the designs and secure patents. In the final design the crankshaft installs from the top, the test engine crankshaft installation was conventional. All of the combustion pressure in the final design is into the primary lower block casting and not into bolted on caps. I am confident that the final designs are much better. Imagine never ever having to remove an oil pan and changing the main bearings from the top.

Yes this is a challenging vision but at least I have a vision. I think about Robin Williams who could have used a vision. From the news reports he had money issues. A 36 million dollar house that he couldn't sell. High net worth is only a number, cash is still king. When the cash stops it all stops. A lot of people with vision die broke or have serious financial issues along the way. I didn't create the 2008 crisis but I was certainly left to deal with it as best I could.

A lot of people were hit hard by 2008 and 2009 and I was not alone. A lot of people have lost hope and feel that America is in decline and will never recover. I am still optimistic and I believe that there are products that can be manufactured in the US profitably. People need good jobs and that is another passion of mine. I have had offers to take this to Mexico or China but my desire is to produce at least the marine engines in the US. Industrial manufacturing is not sexy and this is a long term proposition and not for the faint of heart.

The next step is to build the final design, place it in a test cell and get through the 400 hour NATO test and then place it in boats. You would need 25 to 50 engines. This is not a product that might blow up on the launch pad. It is a basic 4 stroke engine with conventional cam, pushrods and rocker arms and 150 years of history. Proper testing will locate any deficiencies and nothing that shows up will be a show stopper. I believe that this design makes too much since not to pursue it to the end.

I'm loading the gun to shoot myself right now.

I understand, and wish you all the luck, keep us posted!!

Please be careful on forums like this, and think twice before you publish something!!

If you want "yes" men this isn't the place to find them. Also, you'll never have success just surrounding yourself by them.

On the other hand, if you take criticism and address it in your actions, then that can lead to success.

Now, if I were you, I'd be trying to pitch my idea to the major engine builders. If they buy it, they can actually do the prototypes and testing.

Before you pull the trigger, how about posting some of the performance data you have had nearly 6 years to collect.

You just posted more than 500 words in a single post telling us why you haven't put DD out of business yet but not a single line of data to back up your claim of the world record beating fuel efficiency of your engine.

What is the problem? Did your dog eat the printouts?

Loud enough to wake me from a dead sleep - afternoon nap.

Did it sound like a gunshot?

Last we heard from Mr. Buck was:

"I'm loading the gun to shoot myself right now."

Concepts

You are like a snapping turtle. I'm waiting for the lightening to strike so you will turn loose. I haven't even suggested that I would put DD out of business. Outrageous statement again. You really need to chill and you need to ask the right questions in order to understand this. Most of it is on the site but I would like to address one more time the .28 BSFC figure, that you keep harping on. In a previous post I said that I tested a 5 liter 4 cylinder engine that indicated a .28 BSFC. This is absolutely true. While the first prototype engine of my design was a six cylinder, which I designed, built and patented, is a 6.7 diesel engine, the 5 liter 4 cylinder was a engine platform from an existing producer. It was heavily modified in order to prove out my original concepts. The engine was originally designed for 97 horsepower at 22 hundred rpm but when I was finished it was making 340 horsepower at 2800 rpm. The boost pressure was close to 40 psi and I had designed a very efficient after cooler. The turbocharger was being cooled with raw water and was not on the fresh water cooling circuit. I placed the engine in my test cell and I ran the engine for a solid 8 hours at full horsepower. The temperature of the engine never exceeded 185 degrees F. Full power for eight uninterrupted continuous hours told me that I was working in the right direction. My initial approach was to marinize this same engine platform but after a trip to the factory in England, I realized that I could not be guaranteed a reliable supply of base engines. At that point the only thing to do was forget the idea, build your own engine or take the risk of getting in the market and then being shut down due to an interrupted supply (to me the latter was not an option). I had a booth at the Miami show already leased and I had engines painted and prepped to go to the show. I decided to forget taking any engines and instead went to the show and passed out questionnaires seeking input from attendees. At the show I got my first glimpse of the Dynacam engine. It looked like a 55 gallon drum with a shaft stickling out of each end. That was the point that I made the final decision to build an engine from scratch. If that weird engine could run, I was convinced that I could build an engine as well. I bought some 3D CAD software and went to work. I consulted with Gordon Wright, a man with 40 years of engine design experience and a PHD in mechanical engineering. He proofed all of my ideas and was a joy to work with. My approach was to build an engine from bottom to top that could be installed, serviced and repaired quickly and easily while in the marine application. The result is the engine that you see on the site and YouTube. The first prototype ran very well. There were a couple of heat treat issues and one clearance problem but everything worked. There were terrible problems with the electronic fuel injectors. This is why we didn't make as much power as the design was capable of. High pressure common rail is not complicated but it was in the early stages. The Bosch pump worked well but the injectors were something else. In the end the engine produced close to 400 horsepower. We ran it for probably a 1000 hours but never really completed the tuning process. Before we could get the engine where I wanted it, 2008 hit and I was facing more important issues. You can keep arguing over the .28 but if these two links don't satisfy you then we will have to agree to disagree.

See post 8.

improving BSFC in a diesel engine • Speed Talk

Using BSFC #'s

We were using a Land and Sea dyno and according to this publication you might see a .25 at full torque and a .30 at full power. The .293 and .297 was for a Cat truck engine with, I'm sure, an air to air after cooler. The truck boost was most likely well below the 40 psi we were running. With this all understood, the .28 was very possible yet I was still cautious enough to qualify the number as indicated.

For those of you who are still wondering if I am someone's employee, I'm not.

H'mmmm 764 more words and not a single data point showing how your engine has performed since 2008.

You either tested the engine and collected data or you didn't. So far it looks like the Buck engine is blowing more smoke than a Yangtze River patrol boat.

Concepts

Still trying to be kind here. It would be great if you would actually read the post. Post 51 tells you that I have not tested anything since 2008 and my last post says the same. If you want to just be a jerk, please go bother someone else.
