Latest Patents

Haruya Shirase holds a patent for an EGR Control System. This system features two vacuum modulation valves, one that responds to venturi vacuum and 'EGR' pressure, and another that responds to venturi vacuum and induction vacuum. The first valve primarily dilutes the vacuum operating the EGR flow control valve during heavy load operation, while the second valve does so during light load and/or high-speed operation. This combination effectively prevents excessive EGR during light load and high-speed conditions, optimizing engine performance.
