Hey /o I'm planning to buy a diesel mini-engine so I can

This are like it's specifications

Get more info.

If it has electronic injection, common rail or variable injection timing it won't like the biodiesel.

I'll be surprised if it starts at all.

Cummins party's guy here btw. Feel free to ask

You would be way better off finding a small diesel excavator engine or bobcat engine out of a junkyard.

You can even convert it into a generator when you're done.

I wouldn't go and buy a new engine just to test biodiesel on. Goto the junk yard/CL and find a used engine. Also when you make your bio diesel don't forget to fry the fuel. Injection pumps don't handle water well. Good luck.

>So I can prove that my biodiesel works in my college.
Thats not much of a way to test anything. A diesel will run even on used, unfiltered vegetable or motor oil. For a good while at least.

Those are watercooled and rewuire heavy equipment to lift.

This is just some air cooled single cylinder ching chog thing only slightly larger than what you'd find on a lawn mower.

They might be water cooled but they are not heavy at all.

Look up a yanmar 1gm or 1ym for example

Also engines out of water pumps and generators are air cooled.

If you're an ausfag, southern cross used to make hand crank start diesel singles for water pumps and small gensets. Most old farms will have one around and they'll literally last a century.

The biofuel must be heated as the viscosity is too high for a direct injection pump such as the one on this engine. Fifty to sixty degrees will work well but be aware that once the dfo is at this temperature it will be at flashpoint and will be giving off flammable vapour. Treat the fuel system from the tank and back as if it were a petrol fuel system.

Start the engine on dfo and always shut the engine down on dfo. Leaving biofuel to cool in the plunger and high pressure injection lines allows it to gel and form varnish in these tight tolerance parts.

Your drama will be with the 12v output of them onboard charging unit. It is only 3 amps and this is nowhere near sufficient for the fuel heater, let alone the fuel heater and start battery charging. You will have to mount an alternator of some sort.

This will be beneficial for the engine anyway is it needs enough load to get the piston crown and combustion chamber up to working temperature. Idling the Diesel engine and especially one with a comparatively high compression ratio for direct injection results in liquid dfo washing down the cylinder bore through the gaps in the rings by poor combustion. The fuel washes away the lubricating oil causing wear and any biofuel able to enter the crankcase will cool, gel and congeal in the lube oil.

So if you were to mount the engine with a small tank of dfo and another tank of biofuel with a selection valve feeding a 12v fuel heater inline with an electric fuel pump for carb pressure and have the engine drive a GM one-wire alternator with an internal regulator and a decent lead acid battery as a load, I think it would work quite well.

Good luck, have fun.

God damn anon.

You never cease to amaze me

Yeah mate, they're a fair bit smaller than the stuff you find in mini excavators and bobcats. But you're on the right track.
Literally any small diesel gen set, portable fire fighting pump or air compressor (although working compressors get a little exy) would be suited.

He wants to run the engine on biodiesel not wvo. So no need to heat the fuel up.

The kinematic viscosity of the dfo most likely available to him can be up to 24mm2/sec. Kin visc of B100 FAME biofuel measured to DIN standard is up to 6mm2/sec and so will require extra lubricating agents added. For plant based biofuel like that from sugar and maize can be up to 40mm2/sec and will require the heating listed above to lower viscosity to working level.
