Nice 1-71 Detroit Diesel Engine

I toured the DD engine assembly plant and they had this lovely old 1 cylinder 2 cycle engine running on display!

make a good generator

can you convrt a 2cycle gas motor to die

sel???

[FarmallDoctor]

A 2 cycle gas engine just doesn't have the strength built in to produce the high compression pressures required to ignite the injected fuel.

is that a blower i see on it ?

[FarmallDoctor]

All 2 stroke diesels have blowers on them

24v71! 20v149, talk about torque... rumor has it that there is one of those mounted at the north pole and thats what makes the earth spin!! ;)

I want one....I have NO IDEA what the hell i would do with it....but i want one :-)

VERY rare. 2-71s were a lot more common.

@FarmallDoctor for scavenging isnt it??

[mikeshotrodshop]

@FarmallDoctor Not quite. Chicago Pnumatic made 2 stroke diesels that were purely natually aspirated. Do a YT search for this "Chicago Pneumatic 100hp Crank View" I would have just imbedded a link but YT beta doesn't let me. This is a 2 stroke natually aspirated diesel. (non-scavenging) There are other engines out there also. Nice 1-71 though!

exactly 5 more of those, and I'd have myself an extremely acceptable engine

@Michigander79 - strange, but I have seen such things with half of a V8 or something similar... half a 12V71 maybe?

[wildbill0088]

@Michigander79 If they are set up for it the 6-71s can be run on a slant or even laying on their side, some old buses ran them flat on their side to get more passenger space

[bowtie4ever96]

@FarmallDoctor all valved 2 strokes

[Michigander79]

does anyone know if detroit diesel made a slant 6-71?? we got a NC10 aircraft electrical power unit here at work, and the engine is for sure a 6-71 but she aint straight up! just wonderin

[AmoralEngineer]

@FarmallDoctor No you can not. In almost any possible scenario. There are some small 2 cycle gas engines that use glow plugs but thats as close as you'll ever get. I think most of them are on the rc cars. A 2 cycle gas engine is an apple, and a 2 cycle diesel is like a pineapple. They sound similar in name, but you just arent going to make one the other. Large container ships use something remotely similar to the reed valve scavenging of 2 cycle gas engines, but nothing else is similar.

If I'm not mistaking 1-71s were only made up into the 1950s and for marine gensets.
