The 1-Cylinder Detroit Diesel 1-71 Is Nearly Extinct

Рет қаралды 184,685

Күн бұрын

The history of Detroit Diesel roots back to 1938 when General Motors re-organized an older engine company called Winton which it bought back in 1930. It had been known as a large diesel manufacturer and the new firm, Cleveland Diesel Engine Division, was meant to scale up the production line. Developed prior in mid-1930s by GM Research Division, the plant was finishing machines and tooling for a production launch of a more compact power unit.

Over several years of collecting 1-71 information and documenting survivors, he tells us the earliest serial number is #8 and highest is #926.

The roots blowers are also very efficient as they supply pressure pulses rather than constant pressure. Current Achates power designed engines are kinds of like two detroit disel blocks pointed at each other and geared together (with the vale train completely removed.. and on top of that they can hit 50+% efficiency targeting 55+%.

@Retired Bore I don't think any of the achates engines have gone for an electric blower yet... since that would require a pretty beefy electric motor that isn't used 99% of the rest of the time, it would make more sense to just disengage the blower entirely, bypass it and rely on the turbo or a pair of turbos small and large or an electrically assisted turbo at idle. When running unloaded they are obviously 100% drag.... since they arent' doing anything at all so your statement that they are inefficient unloaded is well... it should go without saying. Perhaps an electrically assisted turbo would make a lot of sense as it could also be used to reduce turbo lag.

They were a pain to get started, but would run until out of fuel without any problems, if you kept the fuel tank full it would run a very long time. They need to be topped off with oil a lot.

In short terms, the Detroit Diesels 2-stroker, especially the series 71 was just a scaled down EMD 567s because it uses some principled from the 567 but modified to suit the needs and reliability... However, the only thing that isn't scaled down from the EMD 567 is the Clutched-Turbocharger from the EMD 567D3 series, so they just stuck a Turbo on top of the Blower and later puts an intercooler on it...

Two stroke diesels actually don’t need any valves and oil is carried in a dump like any other engine. An air blower feeds air into the intake ports while exhaust escapes from the opposite side. Fuel is added long after the ports have closed so they are clean. Black smoke is entirely to over-injecting the fuel. Control it electronically and it runs clean.

Because for even an economy car in modern times you would want about 70-100hp. That’s hard to get with a single without it being so big it’s going to be a lot of extra complexity and work to get it smooth. Even then it’s going to shake just because of the big individual power pulses. 3 cylinders are becoming common because it’s an efficiency benefit over a 4 cylinder without adding much complexity or loss of power.

I would love to see an experiment where they made a 2 stroke diesel, but replaced the blower with turbos. I know it wouldn't be practical but I think it would still work, you would just have to power the turbine to spool it up before it could start, maybe with one of those hybrid electric turbos like they use in racing now. The reason it would be interesting to me is because turbos are so much more efficient than blowers. You might even be able to just have a tank dedicated to storing compressed air that built pressure while running and then was used to blow into the engine to get it started and that way you might not even need to spool the turbos. Man I wish I had the time and means for projects like these... I love these fun ideas. Edit: Oh there was a turbo one at the end. I was too exited to watch the whole thing before I started commenting. Very cool. It didn't mention though how it started up though without the positive displacement of the blower.

Yeah I'm pretty sure you could make a purely turbo one work, you would just need to "jump start" the airflow because it wouldn't start with just a turbo but if you blasted some air in during startup I think you could get it going on just the turbo. I could be wrong but it would be fun to try.

@@El_Chompo look for the channel "two stroke stuffing" he did build a racing 50cc two stroke uniflow, as well as a supercharged 50cc two stroke. If you are interested in two strokes his channel is a wealth of knowledge.

As others have said the blower is needed for the engine to run at all. The non-turbo engines with just a blower are considered naturally aspirated.

a normal 2 stroke has a sealed crankcase, detroit diesels do not. this is why detroits need a blower

If you're quoting the fuel usage per hour, I hope you remember that the American gallon is only about 3.75 L, and not the imperial measurement of 1 gal = 4.54L

Never knew that, thanks for correction

No problem. I'm Canadian and come across this all the time. FYI, the gallon the Americans use is still in the imperial system, it was traditionally used in conjunction with wine. Traditionally wine had a lots more solids in it, enough that it didn't take the same volume to make gallon as water.

The really unique detroits are the 51 series, no valves.

This information about the Litrage of each cylinder is correct and is the same for 53 series? because have a website with informations about the 53 series, and doesent match with the 53 cubic inches per cylinder, the 3-53 is 2.6 litre with is already bigger displacemente than 71 series, and the 4-53 goes up to 4.0 litre displacement, I really became lost in this part

@tiesco Жыл бұрын

oh my god my brain is become bigger, i didnt know that the litre is the total volume of all cylinders, i think that is the volume of each cylinder, 4 years blind

Hey I'm a bit off topic, but what happened to the BoostLust channel? I'm curious to know what made you stop uploading to that channel.

I think this one gallon at 3:31 corresponds to 3.8 litres, as it concerns an American company. 😉👍

hey the blower moves the air into the engine thus the word blower, if was to extract the spent gases it would be called a sucker or extractor. due to the open intake and exhaust port the air charge is forced into the cylinder pushing out the remaining gases left over. there i fixed it for you
