Imagefilm NEANDER MOTORS

England’s Lanchester Motor Company was founded in 1899. The firm’s Lanchester Ten, introduced a year later, featured an air-cooled, twin-crankshaft, 4.0-liter flat-twin driving the rear wheels. One crank lived above the other, and each piston had three connecting rods—two light outer ones and a heavier one in the center. The light rods went to one crank, the heavy rods to the other, and the two shafts counterrotated. The result was 10.5 hp at 1250 rpm and a remarkable lack of vibration.

Der Beitrag ist 10 !! Jahre alt und ich habe nie wieder was von diesem Motor gehört. Versenkt wie alles andere auch.

Klasse, bitte mehr darüber

For all commenters that don't understand German: Instead of needing 4 Cylinders to avoid a shaky Engine this symmetric system only needs the lower part of a 4 cylinder engine but has less pistons and less valves. that saves room, weight, money and energy, specially if the desired engine volume is 800-1300ccm

Even if ultimately it doesn't work out something useful will have been learned from this. Just thinking outside the box may end up providing the insight for a completely different endeavor. Keep up the good work and good luck.

"NEANDER MOTOR" absolute "KLASSE", die Vorzüge sind auf Anhieb erkennbar. Auch eine sehr interessante erwähnenswerte Entwicklung, ist der "KUGELMOTOR!!!"

Firma scheint es noch immer zu geben.

Offset Crank, but TWO of them. The Ford Model A had an offset crank . But only offset by 1/8" or 3mm.

Great. Fantastic... So, it runs of course. You don't need to see or hear that. It's very important that we talk about it and show pictures. 😕

This konception of engine should eliminate all vibrations! ... This is ingenious!

Being that this vid is now 10 years old... where is Neander Motors now?

I believe it provides similar output with a lighter and smaller package as well as the built in primary balance. Perhaps they also see a gain from the mechanical advantage of twin cranks and added flywheel effect. There must be some valid benefit for them to have won the tech prize. Note the obvious benefit of being able to keep a slipper piston perfectly parallel in the cylinder.

The Germans could over-engineer a toothpick.

So doubling the frictional losses of the bottom end of an engine is key to more efficiency? Sounds kind of German to me. If it worked Honda would be making these by now.

Да тут есть целый ряд преимуществ!

An excellent design. Eliminating the vibration of the two cylinder machine WITHOUT going to the complexity and width of a four cylinder one ( which also increases the rocking couple) and as an alternative to the "balance shaft" that is used in most modern 4 cylinder car engines. PS to those who talk of "overengineering" I bought a german designed pump. It primes perfectly, puts out almost 50% more water and uses 2/3 the power to do it. It cost double the price but paid for itself in less than one season.

Durch die zweite Welle kommen mindestens vier Lagerstellen dazu und dann noch die Verzahnung, das sind keine vernachlässigbaren Verluste mehr.

Yep just what we needed, more moving parts, more things that can go wrong at our expense, they learn at our cost!!,

G' Day< i would have the rotation direct the other way,,maxamisng the straight drive down and not expecting the con rod and crank to take max force in rotating motion,,

All I can think of is the mess when one tooth breaks
