Detroit 6-71 Startup

The start up of a late '70s Detroit. The signature sound of a 2 stroke Diesel.

0:15 having watched enough KT3406E I thought that thing was going to runaway lol

[@MartinGamer6241]

Me too lol

[@fexploder3281]

I love these old engines, they just sound so good and this engine also looks pretty cool.

[@craigkopcho7394]

The 71 series engines were 2 stroke. I had them in generator service. The regulation was superior.

[@lineshaftrestorations7903]

One of the best methods of turning diesel fuel into noise. 😂

And your transvestite 4 stroke joke series 60 will do the same to

I have the same engine setup at work. I always start her up and let her idle at 750 or so for a minute or two then crank her wild. I know these engines can take the abuse but I try not to have it max rpm’s when I start.

Maaa eso es todo ni la gastada de diesel

[@lastone3926]

Yeah that’s why I can’t hear so well lol

[@jlo13800]

this is an ultra high perfomance 2 stroke

[@timgreen4137]

What???? 🤣🤣🤣

[@deborahchesser7375]

@@jlo13800not sure about that but they’ll run wide open all day so that are definitely tough.

[@jlo13800]

@@deborahchesser7375yes 2 strokes are far more robust that 4 strokes! look how heavy arctic cats new 858 is built and now letts scale that kitty up to 858 CID per cylinder v-16 for a tugboat!

@@jlo13800 I love trucks and heavy equipment, especially the vintage stuff. My cousin rest his soul, owned a 76’ refinery’s substation and ran 4-5 Pete 359’s. One blew a motor once and my cousin had a dozer with worn out finals but a fresh 12V92TA. He put that motor in that Pete and I swear it would run 100 loaded with an old Spicer 15 speed, crazy but cool as hell.

I’ve always heard you NEVER Rev a cold diesel….

[@littlesquirtthefireengine5478]

It's a generator, so it's probably set to go right to full RPM upon startup. Also it's a detroit so... oil schmoil 😁

[@weofnjieofing]

Why are you revving it up so high from a cold start?

[@porcupinepunch6893]

That's a normal RPM for a 2-stroke Detroit diesel

[@rileydj8764]

I agree, worked on them for 8 years, that is not idle!

[@Adam_Poirier]

To answer your question correctly it's a generator. That's why it immediately went to full throttle.

[@paulhorton5612]

As it's a 2-stroke there's twice the power impulses per revolution, so it sounds like it's going at double rpm

[@user-xh2so8ef3o]

@@paulhorton5612 Yeah but it's not a low idle - it's running at rated rpm which, depending on the generator, could be 1500 or 1800 rpm or something similar. I'd say it sounds like 1800. In a vehicle application, a 71's usual range is 500 to 2100, same as four stroke engines like N series and 3406B

[@samuelegbert2199]

So no warm up necessary on a cold start ????

[@chickencrapoperator]

[@trucking604]

Nothing like revving a cold engine to maximum RPM.

[@user-rk9wm6rn3b]

Silly

[@kellywilson8440]

Warm up , Nah !
