MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202617086199 A) filed by Yamaha Hatsudoki Kabushiki Kaisha on July 14, 2026, for Alcohol-Containing Fuel Engine System And Vehicle.
Inventors include Matsuyama, Ryota; Atsumi, Masaki; and Iguchi, Wataru.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: Provided are: an alcohol-containing fuel engine system capable of achieving both reproducibility of early combustion and target trackability of the engine rotation speed in an engine in which in-cylinder injection is not performed; and a vehicle comprising the alcohol-containing fuel engine system. The alcohol-containing fuel engine system comprises an alcohol-containing fuel engine, a starter motor, a control device, a combustion chamber, an intake passage, an intake valve, an air intake amount adjustment device, and an in-passage alcohol fuel injection device. In a first combustion cycle after causing the starter motor to start rotation of a crankshaft, the control device causes the intake air amount adjustment device to take in an amount of air smaller than an amount of air corresponding to a high idle state in the alcohol- containing fuel engine and causes an amount of an alcohol-containing fuel smaller than a maximum injection amount to be injected into the in-passage alcohol fuel injection device so that effective combustion occurs from a second combustion cycle following the first combustion cycle. In the second combustion cycle, the control device causes the intake air amount adjustment device to take in an amount of air smaller than the amount of air corresponding to the high idle state of the alcohol- containing fuel engine and causes an amount of the alcohol-containing fuel smaller than the maximum injection amount to be injected into the in-passage alcohol fuel injection device.
