Engine Start Ups

As requested, a thread swerve of engine start ups to prevent spoiling the V50 thread - I dunno about anyone else but this is fuggin fantastic.

 

Quite a long video this one and probably best to watch on a lap top/PC screen for the full effect - listen out for when he throttles it back and blips it at around 3:50 & 4:20. A Rolls Royce 27 litre V12 ~600 bhp & 1400 lb-ft Meteor tank engine.

 

And last but not least a Bristol Hercules Radial - quite a long video this one but hey it keeps me off pornhub... ahem

 

Fantastic ! and the little bit of popping and spitting just adds to it.

Are these the motors those nutters used to put in cars in the 20s and then hammer round Brooklands at unfeasible ton plus average speeds. Usually wearing only a leather cap, googles & a boiler suit.

 

Even more fantastic!! I think I'm right in saying that radials are known for their high torque & I think the Americans used them in some of their tanks.

And I can never figure out the con-rod configuration on them either... I always have to look at a diagram.

Good job Ducati didn't make the big ends for them

 

It always amazes me where do they keep all this stuff? in a gert big flame proof shed at the bottom of the garden.

And where do they find these motors, and what about spares? Just where do you get a set of 10 piston rings for a WW2 Russian aero engine?

 

Evidently it's a two stroke diesel & I quote " The engine weighs around 60,000 lb (27,216 kg), and the flywheel alone weighs about 12,000 lb (5,443 kg)."

 

It most certainly does. I dunno what it is about stuff like this but I find it just fantastic... and don't get me onto stationary engines at country shows.

Comment quoted from youtube

"For those who don't know, This is called an inertial starter. That pole would be connected to a gear inside that hole, which would be connected to a few other gears in a step-up fashion. (Gear reduction but the opposite way). The other end of that gear train would be a heavy gear that connects to the engine's flywheel (connected to the crankshaft). Now that gear is heavy for a reason. When you got that last gear up to a high enough rotational speed, the momentum, the driver would use whatever mechanisms to connect that gear to the flywheel. Then, the energy of the inertia of that gear's fast rotation would go into the flywheel, turning it. It wouldn't turn it for long. But it would be just long enough to get the engine started. Which is why i love german engines. They barely make a full revolution before starting up. Which, even by modern standards, is damn impressive. Even as old as this big heavy Maybach engine is, it started up in no time at all! And in my book, the mark of a well-designed engine is the quick fidelity of it's starting process."
