Its been said before but its true this engine IS truly poetry in motion, when you think 36 years before. cars had two cylinder engines and aircraft had yet to fly... its a miracle and we needed one real bad with what was to come...... some say the war was won because of the MERLIN....

And to think they had forged cranks, forged rods, forged pistons, dry sumped, two stage superchargers to compensate for less oxygen higher up, even the valves were filled with solid sodium, so if they got too hot the sodium melted and took the heat away from the valves stopping them over heating or burning up, all in 1940’s.

Folks today couldn’t build a Merlin of yester year
@mrl222223 жыл бұрын
well they could, but why? It was great engineering by 1940's standards by todays standards it would be underpowered for it's weight and size, unreliable and pretty inefficient. This engine got about 1hp/lb. a Modern engine gives you 3 hp/lb and even as heavily stressed as the mrelin was still has a service interval that is almost 5x a merlin. Don't get me wrong, I love them. But 70 years of engineering has improved piston engines

@@MarsFKA I've fixed lots of these with timing failures, the tensioner fails suddenly and the chain goes slack then jumps a tooth or three on the right hand camshaft, so the piston then hits the intake valves and destroys the cylinder head, big bill!

Why middle cylinders in each bank go the same phase? Why not an 120 degree EVERY cylinder diferrence like all modern 6 cylinder engines?
@pietroseven82283 жыл бұрын
Exactly what I wanted to asking for. But when I look in the drawing it seems to be correct.
@MichaelPolymhxanos3 жыл бұрын
@@pietroseven8228 After I wrote the question, I thought of it more. It is correct, I was wrong. In 6 in line cylinder engines, the one half 3 cylinder is the MIRROR of the other 3 cylinder half, and so middle cylinders go up and down the same. This configuration is the most symmetrical, and the most vibration cancelling. Each 120 degree 3 cylinder alone, although primary balanced, produces a secondary tendency to ''swipe left''. Having a MIRROR 3 cylinder with the exact opposite tendency, cancels all, and SO the video is correct after all.
@andypdq3 жыл бұрын
@@MichaelPolymhxanos The straight six has perfect balance, no heavy crank counterweights or balance shafts required. Because straight sixes have perfect balance they can be made very big, most big truck engines are straight sixes. V12s are just two straight sixes running on a common crank. Unlike the V6 or V8, which have to have specific angles between the banks to run smoothly, a V12 can have any angle between the banks which is convenient. This is why large inline aero engines tend to be V12s.
