Notice anything interesting about this cutaway of a diesel engine?

and yes, it does run on diesel #2.

I guess a few years ago Mercury decided that they wanted to supply the military and commercial operators with outboards that could use a single fuel source - diesel.

Basically its just a 3.0 V6 2 stroke gas engine, but tuned to run on diesel fuel. They don’t run on the diesel cycle, they actually use a spark to ignite the diesel...a thing I didn’t even know was possible.

They say the engines are 95% common with the gasoline 2 strokers. What an oddball motor.

They sound...strange.

A high revving diesel? Sound super weird.

It probably isn’t revving all that high, remember 2-strokes tend to sound like they are revving twice as high as they are.

Well this is certainly isn’t a real truck.

Nah, 4500 rpm redline, just sounds twice as fast because 2 stroke.

I guess not... but does it need that spark plug in a diesel engine?

Its not TECHNICALLY a diesel engine. Its a 2 stroke gasoline engine...that happens to run on diesel fuel somehow.

Isn’t adding a spark something the skyactiv diesel does?

Oh right shit, reading is fundamental. Totally missed the 2 stroke part

Totally missed it was a 2 stroke, heh.

No, the Skyactiv D uses glow plugs and runs a true diesel cycle. They are both low compression though.

It has a hemi......brah.

correction, it does rev to 6000

Apparently they are great for swimming pool applications for regular people.

“This engine does not meet EPA, C-ARB, or CE exhaust emissions requirements. A national security exemption or equivalent is required under 40 CFR 1068.225. This engine is not intended for installation on recreational craft in the European Union; it does not conform to the exhaust and noise emissions requirements of the Recreational Craft Directive 94/25/EC as amended by 2003/44/EC.”

Interdasting. Is that what they do with the M1030 diesel motorcycles we have had in the military? I’ve seen them but I never thought about it.

edit: Nope

Dressed in desert camouflage paint, and disguised behind a military code name, “M1030-M1”, this Haynes-DT machine is actually a Kawasaki KLR650 with a diesel engine. Hayes Diversified Technologies of Hesperia, California saw the potential in the KLR for conversion to run on the multiple fuels the military uses around the world, but some modification was required.

The Kawasaki KLR650, first launched in 1984 is still going strong. It’s the default choice of small capacity, single cylinder, adventure touring bikes that can take you to the mailbox or to the end of the world, and back. It’s tough, flexible, fast enough and reliable.

And in stock trim it’s a good choice for the modern military except for the fact that it is powered by gasoline. Many armed forces around the world associated with NATO (North American Treaty Organization) have determined that all of their vehicles should be capable of running on multiple fuels, specifically diesel and biodiesel in peacetime, and JP8 aviation fuel and kerosene in time of war. The U.S. Marine Corps joined together with Cranfield University (in the United Kingdom) and Hayes Diversified Technologies of Hesperia, California to develop such an engine.

The resulting “diesel” liquid-cooled, single cylinder displaces 584 cc and uses the original Kawasaki main cases and 5-speed transmission but with a new piston and cylinder and the other components necessary for it to run very high compression required when using these multiple fuels. Producing 28 horsepower, it has a top speed of 85 mph. Changes called for by military spec also makes it capable of running in at least two feet of water, and there’s black-out lighting, even an optional infrared headlamp. Handlebars look super tough, and the oversize fuel tank is good for a bit over 400 miles.

2004 production was something over 500 units. Further development of the Hayes-DT bike has resulted in an M2 version of 670 cc which has a top speed of 95 mph. Hayes has run these engines successfully at the Bonneville Salt Flats; top speed of 121.212 was reached! Entered in the Vetter Fuel Challenges, Fred Hayes bike builder and rider, the “streamliner version” won outright with 162 miles per gallon of Diesel fuel. There has been discussion of a civilian version.

Specifications:

Engine: Double Overhead Cam Single, Liquid Cooled

Bore & Stroke: 100mm x 83mm

Displacement: 584cc’s

Carburetor: Keihin CV

Ignition: Electronic

Starter: Electric

Clutch: Wet, Multi-Plate

Primary: Gear Driven

Transmission: 5-Speed

Frame: Chrome-moly, Semi-Double Loop

Brakes: 280mm/200mm Disk

Wheels/Tires: 21 / 17

Wheelbase: 59 Inches

Weight: 390 Pounds

Top Speed: 85mph

The Kawasaki M1030B1 is an upgraded M1030 while the Kawasaki M1030M1 runs on diesel fuel instead of gasoline. The Marine Corps will modify its fleet of M1030 motorcycles to incorporate the M1 multi-fuel engine which will meet the requirement for a single battlefield fuel by 2003. The engine will be capable of burning JP4, JP5, JP8, Kerosene, and diesel fuel.

No I think that was actually a diesel.

Mutlifuel engines are rad, if slow.

HammerheadFistpunch > kanadanmajava1 05/23/2018 at 18:50

Yeah I noticed that. I suspect the reason no one is doing this is because the benefits are minimal outside of running a single fuel source and because the emissions are BAD.

All things considered spark-igniting diesel fuel isn’t actually that far-fetched. Question for me is does it use regular sparkplugs or special ones due to the higher ignition temperature of Diesel?

MultiplaOrgasms > PartyPooper2012 05/23/2018 at 20:55

Well yes since the compression ratio on this is not sufficient to reach the ignition temperature of Diesel.

jimz > HammerheadFistpunch 05/23/2018 at 21:15

I’m’a guess the compression ratio is high enough to get the fuel to vaporize but not auto-ignite. once diesel or kerosene is vaporized, it’s spark-ignitable. this basically looks like a gasoline direct injection engine.

most normal gas engines don’t have high enough temps under compression to vaporize a middle distillate fuel like diesel effectively.
