Qianjiang **motor company challenges traditional design with a revolutionary new design. A few days ago, it applied for a patent for a unique "V-shaped" single-cylinder engine, which has the outline of a V-shaped twin cylinder in appearance, but in fact only one main cylinder (front cylinder) is responsible for power delivery, and the auxiliary cylinder (rear cylinder) is only used as a counterweight, and the piston inside the auxiliary cylinder has a rectangular hole in the middle to ensure that the piston does not participate in the compressed air work.
Qianjiang is not the first company to experiment with this design. Ducati had made a similar attempt with its Desmoquattro twin-cylinder engine, creating the legendary SuperMono single-cylinder racer. During the development of the Supermono, Ducati initially retained the rear cylinder, removing its power function only by removing the rear cylinder head to maintain balance. However, as the development progressed, the extra friction of the rear cylinder piston consumed too much power, which eventually led to the birth of SuperMono.
Today, Qianjiang **motor is exploring this design concept, and they have retained the rear cylinder that does not participate in the power delivery and made it form a 90-degree angle to the main cylinder, creating and patenting this unique "V-shaped" single-cylinder engine.
Compared to the traditional V-twin design, this single-cylinder engine from **motor is significantly different. In their design, the rear cylinder had a much smaller bore than the main cylinder and was equipped with a weighted piston for balancing only. In order to avoid unnecessary compression of the piston, a large hole is specially designed in the middle of the piston. In addition, the rear cylinder head is cast in one piece from the engine body, ensuring the tightness of the engine.
What is the motivation for this design? Obviously, it has significant advantages. The Qianjiang design philosophy is the same as Ducati's original intention when developing the SuperMono, which is to achieve the same balance effect as the traditional 90-degree V-twin with this single-cylinder engine, without the need for additional balancer shafts or other counterweights. Although the official **motor has not yet revealed which model this patent will be applied to, and it is not clear whether this innovative design will encounter the same challenges as Ducati's supermono, or bring new opportunities to the domestic motorcycle market, but undoubtedly, this design shows the forward-looking and innovative spirit of Qianjiang **motor in the field of motorcycle engine technology.
