Title: Innovations of Hirotada Yamada
Introduction
Hirotada Yamada is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of internal combustion engines, holding a total of six patents. His work focuses on improving fuel injection systems, which are crucial for enhancing engine performance and efficiency.
Latest Patents
One of his latest patents is a fuel injection control apparatus for an internal combustion engine. This innovative device infers fuel temperature from cooling water temperature and intake air temperature. From these inferred temperatures, a correction coefficient of the air-fuel ratio is determined using data stored in a map. The map is designed so that as the inferred temperature of fuel increases, the correction coefficient of the air-fuel ratio also increases, resulting in longer fuel injection times. Additionally, an ineffective injection time is corrected based on the inferred fuel temperature, leading to a more accurate fuel injection time calculation.
Another significant patent is for a fuel supplying device for an internal combustion engine with multiple cylinders. This invention includes several fuel injection valves and a fuel pipe that directs fuel flow. The design allows for different start timings of fuel supply to various holder means, ensuring optimized performance for each cylinder.
