Latest Patents
Kumasaki holds a patent for a flexible tube designed to be used downstream of an exhaust path from an engine. This flexible tube consists of an outer bellows as the outer tube and an inner bellows as the inner tube. The pleats of the inner bellows are smaller in depth and pitch than those of the outer bellows. A buffering space is provided with a gap between the pleats' bottoms of the outer bellows and the pleats' tops of the inner bellows. Additionally, a partition that splits the exhaust path is disposed in the inner bellows. This design improves sound insulation and suppresses the lowering of the exhaust gas temperature, leading to a quicker temperature rise of the exhaust gas fed into the catalytic converter. Consequently, this promotes the activation of the catalysts, enhances the capability to purify exhaust gas, and improves exhaust efficiency, thereby increasing the output performance of the engine. Kumasaki has 1 patent to his name.
