How would one make a diesel rocket?

[BigNorm]

The aluminum block of the rocket would fail under the pressures that a diesel operates under. Need a replacement engine.

Diesels are heavy. The 3.0 v6 in my Ram weighs 50# more than a 5.7 liter hemi. Also have a Dodge with a 5.9 Cummins. The torque and hp 240 hp /460 for the v6 and 305/560 for the Cummins would tear off the final drive of the Rocket, never mind the transmission.

I had a 2.2 liter diesel in my Mazda pickup that cranked a massive 59 hp, naturally aspirated. You could bump that 20% with turbocharging. It might fit.

Seems like a diesel would be either best suited to off road bikes where torque, fuel economy and reliability were important. Kawasaki builds one. Or, large luxury touring bikes, where a buyer wanted to fork over an extra $8 grand so they could get 55+ mpg.

What is the difference in pressure though weather it is gas or diesel? I imagine running 16:1 gas is a track bike. I wouldn't want to run that CR every day. Thanks for the Mazda idea though. That's the kind of input I need. A V4 Diesel might work well on a Boss Hoss platform as well. The big why here is POWER AND ECONOMY. That and I like to fawk with shyt.

"The 2.2-liter oil burner is quiet, smooth, and loaded for bear with torque to spare. Available in standard (148 hp at 4500 rpm, 280 lb-ft of torque at 2000 rpm) and High Power versions (173 hp at 4500 rpm, 310 lb-ft at 2000 rpm), we drove the latter. A delight with either the six-speed manual or six-speed automatic transmission handling cog-changing duties, the stronger diesel does without the extra hassle of an exhaust after-treatment solution to meet European emissions regulations. Shove is available right off idle, and the diesel pulls strongly to its redline. Only in the quietest moments are strains of clatter or injector tick audible; at speed on the highway, the diesel is indistinguishable from its petrol-swilling sibling.

According to Mazda, the 2.2-liter’s compression ratio of 14.0:1 is the world’s lowest in a production diesel engine. This enables the adoption of an all-aluminum block, lighter engine components, and optimized combustion timing. We had only a few hours with the engine, but we came away convinced that it could make a run at dethroning VW’s TDI as the mass-market, family-sedan compression-ignition king."

That sounds like it deals with the weight issue.

Why not get serious and whip up a couple of these that run on toenail clippings..............

What happened to that tight budget you have posted about in earlier threads? Sounds like an expensive endeavour

 

[BigNorm]

I got real life issues I'm trying to take my mind off of. Nothing is cheaper than a paper build. It's all good until you start buying parts.

 

[IMFASTTOO]

You absolute worst when it comes to giving your undiluted opinions. How about some ideas to make it work. I know you have some.

SORRY I cant get excited about this idea

we can dream @BigNorm, we can dream

Have you ever driven a turbo diesel?

I work for Ford, and have driven more Super duties than I care to remember, including the new 2017 which is a freaking beast.

So once again it looks like Rods may be the weak link. Rods can be made stronger. I wonder what the journal sizes and rod lengths are on the Volkswagen TDI motors? Mercedes? Ect.

I have not heard of any rods breakingbut Crower makes better ones for the rocket already. I have seen them damaged whenyou spin the bearings and lose or have intermediate oil pressure. The worse scenario I have seen did not hurt the OEM rods but there was a strain on the crankshaft even though it is forged.

If you want to spend a lot of money that you will never even come close to recovering even at 100 miles per gallon if you ride every day and most nights and you don't mind terrible performance this might be a perfect way to waste a year or two. Diesels usually run less than 2500 rpms so your top speed would be limited unless you fooled with the gearing. You might try to get a 3 cylinder KUBOTA out of a tractor as the dimensions are close. This is more of a nightmare than a dream. I actually rode a diesel powered motorcycle once. Other than being an oddity there was nothing that was memorable about it. Most projects have something to gain but I haven't figured out what this one is.
