The rare motorcycle engine you have seen, you will not guess, Cubica is a superb bike and almost 100 years old

There are no limits to creativity in the world of engineering, yes, okay, money puts obstaclesBut this is not the state of the four engine of the interested British motorcycle Ariel Square.

The motorcycle we show you on this page is a rare, which is a classic naked The machine is all about, its architecture and displacement and all, this idea is almost 100 years old! The reason for this motorcycle is that we will focus on its machine that avoids the details of its rotation or the remaining components.

British Engineer Edward Turner designed – who is a few years later He directed the Triumph brand- the first Ariel Square was shown at the Olympia Moto reception in four in 1930.

The first model was Cubicaba 500 cc, 4 cylinders, air refrigerated I had valves on the head of the cylinder, but the camshafts in the motor constituency. However, four cylinders are not online, but they are “box”, two front and two rear cylinders, such as two two two -double machines attached to each other.

There was uniqueness. No other model is such a machine like this From there, its section is born four square, which means four in a picture that refers to its cylinders.

The reason for this architecture was that it had the power of 4 cylindersBut occupied the space of a pilindrical engine. In fact, the first motor prototype was installed in a model with a cylinder and a 250 cc machine, and entered without complications! This compact square four.

He was very compact and thanks for that he had two opposite -drick crankshafts -Go parallel to each two cylinders, functional vibrations canceled each other, so it was a very soft machine. And to further enrich their operation, the pistons, which were climbing and unitedly reduced, were “corners”: the piston’s right back piston reached the Dead point at the same time. Thanks to this, the engine had the largest sweet and winding operation.

He had a carburetor on the front and back of the cylinders In subsequent cylinders, each fed two front and rear cylinders respectively. The exhaust collector- two, so it looks like a two-wheeler- the only part of the cylinders left, the only part of it. As you can see, a regular motorcycle is completely different from the engine. In the later versions, the carburetors are behind the rear cylinders, and each side will feed two cylinders on each side.

This machine in the picture was formed and removed a short time later, Going to 601 CC before the total redesign is a 4G model in 1937, with a machine with the same structure, but with the chain transmission- like the current motorcycle- and ¡995cc!

But this machine was fully prepared in iron smelting, Volume, cylinders and cylinder head, so he had two problems: he was overheated and weighs a lot.

So, in the following redesign of 1949, finally, butt and crancases were prepared In aluminum smelting, its weight greatly illuminates, which improved the cooling and benefits of the Aeriel square four version.

Until now, all four square people had two escape collections with collectors They were compiled from two to two, but in 1953 they were separated, 4 beautiful collectors from the engine, the version you could see on each side of the machine on each side of the machine. Mark II was born.

Thanks for this detail, the power is upgraded by reaching 42 hp and square It became the new member of the “One Ton” motorcycle league, which is capable of reaching up to 160 km/h. “Ton-Up Boys” are the young insurgents of that time, “Rockers”, who are capable of reaching these motorcycles at 100 miles, and have always been in a dispute with “Mods” and their Lambota.
