Do you know that a square 4 engine was a thing? In fact, the initial design is about 100 years ago than a person named Edward Turner. He was a motorcycle designer in the UK, which wrote a compact engine that must have tied two small twin cylinders to one four pot. It sold the design to a company called Ariel Motors, and thus the air square was born four.
No one for the four benches sticks to a couple of inline twins together. As this video is from YouTube channel Driving 4 answers It shows, this engine is really a square shape that indicates the crank shaft straight down with the cylinders. Yes, that is Crank shaftDesign design uses two anti -rotating crank shafts that are connected to the finished fly wheel. Cranks trails to each other for 180 degrees, and pistons are similar. As a result, the firing order is similar to that of the Inline Four.
Without being more technical, it all leads to an engine that is naturally balanced and smooth. Based on the video, it doesn’t even look bad. And the square design makes it fully compact, basically takes the same place that is usually occupied by V -twin or even a large single cylinder mill.
There was not just one flash in the Square Four engine pan. Air motors created a Square Four Motorcycle for about 30 years, and the Square Four Engine also used some other motorcycle manufacturers. It improved the low lower power, but for the moment it was an expensive engine, and it was suffering from high heat problems.
There was also a valuable small room to keep the engine feeding the engine, which was fine until the power band was low in the Rio range. But since the motorcycle technology was manufactured in small, high RPM engines, the low -speed square four could not remain. Air eliminated the production of Square Four in 1959.
The video notes that technology is developed at a location where a square four can grow. But the world is slowly moving towards power power, it is probably an engine design that will only be present in history books.
