Title: Innovations by Takeshi Yokoo in Diesel Engine Technology
Introduction
Takeshi Yokoo is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of diesel engine technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and performance of diesel engines used in vehicles.
Latest Patents
One of his latest patents involves a diesel engine designed for vehicles. This innovative engine includes an engine body with a cylinder that is supplied with fuel primarily composed of diesel. The geometric compression ratio of the cylinder is set within a range of 12:1 to 15:1. Additionally, it features an Exhaust Gas Recirculation (EGR) system that allows a portion of burned gas to remain inside the engine body cylinder during specific operating conditions, particularly when the engine load and speed are relatively low. The EGR system comprises an EGR passage partially formed within the engine body, an EGR control valve for adjusting the flow rate of burned gas, and a controller to manage the valve's opening.
Another patent by Yokoo also focuses on a diesel engine body with a geometric compression ratio within the same range of 12:1 to 15:1. This design includes an intake valve and an exhaust valve for managing the intake and exhaust passages of the cylinder. The engine is engineered to partially recirculate exhaust back to the intake passage during low engine load and rotation speed conditions, optimizing performance and efficiency.
