E-tec diesel ?

RibRoy · 26 June 2006, 16:42

Anybody got som more info about this ?
A 200 hp running on diesel would be great.

Do a pair of radical new Evinrude outboards offer a tantalizing glimpse into the future? The company stands poised to unveil E-TEC two-strokes programmed to burn diesel, jet fuel, kerosene or bio-diesel, as well as good old gasoline. Dubbed the Vindicators, two models are offered, rated 50 and 200 hp. The first engines off the assembly line will be assigned to the Department of Defense. Multi Fuel Engine (MFE) technology will allow the U.S military to transport outboards via aircraft or ships without having to deal with volatile gasoline fumes. Once the motors are in an area of operation, switching between the different fuels requires nothing more complicated than flipping a switch. Spray-painted tactical (non-reflective) black, the 50-hp model features tiller steering and rope starting, while the brawny 200-hp model has electric starting and remote steering. Beyond multi-fuel flexibility, what gives these E-TECs added value in a tactical setting is their zero break-in period. They can be run at full throttle right out of the box. And, because they require extremely low maintenance, they survive longer with less care.

Have you been sniffing the glue? Sound like a lot of wishful thinking!

I did mentioon this a while ago - people thought I was mad!!! Also EP Barrus have developed a Merc 50hp that also runs on jet fuel. There used to be a bloke on here that works for them - mentioned it ages ago!!!

there really should be no problem, the military have been running 2 strokes that run on petrol, diesel ,Heating fuel and Jet A1 for 20 years or so,they put the engine in a Chieftan tank, leyland multifuel L60 engine,
also to get around the fuel shortage a while ago, i put in a mixture of petrol and diesel in a Diesel Mondeo (hated the car, thats why i did it) bloody thing didnt blow up tho, kept going!!
anyway going off on one, Hurry up Evinrude!! release the engine!!

Yes but a diesel engine is a big heavy old lump & will burn crappy fuel!
A petrol 2 or 4 strock is a bit more fussy!

The only problem is that when that 200 E-tec is burning diesel, you need to replace the spark plugs every 10 hours!

Yeah im still Here!!!, Yes we have bulit 50hp's that run on Jetfuel (F44/JP5/JP8) and diesel and petrol. Spark ingnition diesel engine. And this one you dont need to change the plugs every five minutes. We can also run optimax's on jet fuel (with a few modifications!!)
Have a look at www.barrus.co.uk its on the website somewere!!

I know an outboard would need mods to run on the stuff neat but what about a mix - say 50:50 or 60:40 petrol/kero?

Matt · 30 June 2006, 16:48

One of the beauties of the weasel is the high compression ratio makes it nice and fuel efficient (Carnot cycle, if I remember correctly). I'm guessing that a spark ignition diesel loses this?

What's starting like - I can think of a few diesels that struggle to start without lots of heat, and 1 raceboat (very low compression) they used to have to preheat the engine for several hours to get it to start.

Anyone know the calorific value of diesel vs petrol?

codprawn · 30 June 2006, 17:07

LPG avg 46930
Petrol avg 44750
Kero avg 43990
Diesel avg 43320

Kero(jet fuel) would be better than diesel - it's also a lot thinner.

That interests me too. Would it have a tendency to gum up the works at all?

Obviously the higher the amount of kero the more likely it is - in some countries the petrol you buy at the pumps is doctored as much as 60% kero.

Ideally you want 2 tanks - start on pure petrol - switch to the petrol/kero mix - and then pure petrol again before shut down.

Can Turbodiesel give us any clues as to how it's done - or is it secret? Do Barrus sell conversion kits? Are there any major problems with engine reliability?

Sadly, I'm old enough to remember petrol/parrafin engines - I always thought they smelled rather nice, though I think they used something called Tractor Vapourising Oil. TVO.

Woe betide you if you let them stop without switching back to petrol - oiled up 2 stroke symptoms plus.

Probably not allowed to say how its done!!, and no we dont sell it as a kit!!. The engine looks pretty identical to the that standard production engine thought. The engines are still on Trial at the minute so they are having lots of hours put on them by various select people on boats. I just go out and check them every 100hrs or so.
