20V with Yanmar Diesel

[dgeiler]

I know this has been discussed on TO before and with limited access to diesel fuel on most lakes a diesel powerplant option is rather restrictive, but still very intriguing. I found it very interesting to see a Tige' 20V retrofitted with a diesel engine.

A little hard to read this one but so cool. $1.2 gallons an hour. Wow.

I may have missed the specs for time to plane, top end etc.
I did not have a lot of time to look at but I wonder how it handles a slalom skier deep water start and boarders. Sure wish diesal was more practical.

i only makes sense to start using diesel... cleaner... more powerful/efficient... tons of torq... lower maintenance... If they start building them they will catch on but right now just a ton of haters because they are thinking about the OLD diesel not the new technology diesel

[Jason B]

I think a company just needs to DO IT and do it well and they could catch on. Yamaha was thought to be absolutely BONKERS when they created the YZ400 4-stroke MX bike to race the nationals against well established tuners and their 2 strokes. Doug Henry went and won a championship on it the first year (on a one-off prototype no less). Wanna guess how many 2 strokes race at any given SX or MX? ZERO! They had to create a whole new mini-series for them...

Anyway, moral of the story is....if they make them and make them better they WILL catch on. The results would speak for themselves and people would grab them up.

I think Mastercraft offers a diesel option?

But I think its like $30k more.

I think talltigeguy said that they stopped offering that option after having major problems with almost every one they installed. But I'm not sure.

Whats the smell from the fumes like back there for the wake boarder?

It's probably not nice. Maybe an FAE would help???

As for cleaner than gas...I have never heard of a PZEV diesel engine but they sure make a lot of them in gasoline applications. Diesel will never be cleaner than gas. Blame it on the fuels. Just a simple fact of life.

Technically Ford does have a concept PZEV diesel. But boats will never see it. At least not in the next 10 years if ever, most likely never.
It takes a lot more emmision control to make a diesel clean.

A selective catalytic reduction system – this uses urea to control NO emission
A catalyzed diesel particulate filter for soot reduction
Diesel oxidation catalysts to reduce emissions
Dual pre-turbo metallic oxidation catalysts – this allows for reduced cold-start emissions
Dual wall, air-gap exhaust pipes to retain heat in the after-treatment system
A hands-free capless fuel filler

When you start introducing DPF(soot reduction) into diesel all your mileage gains go out the window!!

how is diesel not cleaner then gas? In what regards? Diesel is cleaner then gas. SPBFan's son did an experiment on it with my truck and his sensors that the state of cali use couldn't even register the emissions it was so low....?

[petrey10]

i agree ^^^.... Diesel NOW is cleaner than gas... 5-10 years ago yeah it was real dirty but today diesel is more efficient and cleaner... I like diesel too because the US is a major producer AND biodiesel (blend) is a good option in the alternative fuel category (much better than ethanol)

How many emission controls are on a gas vehicle? EGR, EVAP and one Catalyst.

How many emission controls are used in todays diesel:

1.A selective catalytic reduction system – this uses urea to control NOX emissions

2.A catalyzed diesel particulate filter for soot reduction

3.Diesel oxidation catalysts to reduce emissions

4.Dual pre-turbo metallic oxidation catalysts – this allows for reduced cold-start emissions

5.Dual wall, air-gap exhaust pipes to retain heat in the after-treatment system

6. EGR

7. EVAP

Do you still think diesel is cleaner?

Yes diesel is cleaner than ever before in history but not cleaner than gas.

If diesels were so clean they wouldnt have to go through a regen cycle every 200-500 miles in which raw fuel is dumped down the exhaust and into the DPF to clean all the soot from the so called "clean diesel".

Now they are adding urea downstream into the exhaust to help control NOX.(you have a seperate tank for that) And if you run out of urea you will be limping to the next service station praying they have some in stock.

As for your diesel not registering any emissions, I assume this was at idle and no Dynamometer testing was used.

[petrey10]

i haven't heard of that is that done by the vehicles computer control of the vehicle somehow?? anyways I also think that you are kind of missing the point the exhaust from diesel is now cleaner than gas... yes i know they might have all those fancy things put on but the fact of the matter is after they are on the emissions are cleaner... Just my opinion not trying to be rude or anything so don't take it that way

[Domsz06]

i guess I don't understand where your coming from. Your basing how many "clean" devices a engine has on whether it's clean? all over there is facts that diesel is cleaner. I'm just confused.

also diesel is present in all european cars, audi, bmw and mercedes are all producing diesel cars. Cali didn't start doing emissions tests on Diesels till just this year.

Diesel is a lighter fuel, so it burns cleaner as well.

diesel always had a bad rap cuz it produced "the black smoke" suete.

read this article. http://tdi.vw.com/tdi-academy-clean-diesel-vs-gasoline/

all the things you mentioned just make diesel meet the Bin 5 new requirements from the governement.

Actually:

3-way converter - platinum, palladium, rhodium to convert HC's, Co and NOX to Co2 and H2O.

Closed fuel system: Canister purge, cap, pressure/vacuum sensor on tank.

Closed cooling system: Pressure cap and 190* thermo

ECM and related: Heated O2 sensors = at least 3 - one at the manifold, pre-converter, and post converter, ECT, MAP/Baro sensor, MAF sensor, TPS, Knock, Crank, Cam sensor, IAT (intake temp), etc.

I'm sure there are more, i've just been out of the game too long

Now, as far a diesel being cleaner then gas, good question. They are too different to be able to do an apple to apples comparison. Diesel and gas do not produce all of the same emissions. With diesel, the 2 biggest culprits are sulfur emissions and carbon particulates. Both of which have been addresses heavily in the last 20+ years, both during the refinery of the fuel and on the vehicle itself. With gas, we have Co, HC's and NOX. These have also been addressed with how the fuel is refined (blended) and with the engines themselves.
