Title: Akira Tokuda: Innovator in Internal Combustion Technology
Introduction
Akira Tokuda is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of internal combustion technology, holding a total of 3 patents. His innovative approaches have led to advancements in carburetor and fuel injector systems.
Latest Patents
One of Tokuda's latest patents is a method for controlling the air-fuel ratio in a carburetor of an internal combustion engine. This method prevents fuel from flowing into an air bleed passage when the tapered needle valve is nearly fully closed. By controlling a step motor connected to the needle valve, the invention maintains a constant level of minimum bleed air. Additionally, the method involves continuously driving the step motor to axially vibrate the needle valve, ensuring that fuel does not flow into the air bleed passage.
Another significant patent is for a fuel injector for an internal combustion engine. This invention describes a method of driving a valve in an injector that intermittently injects liquid fuel. The valve moves reciprocally due to the attraction force of a solenoid coil and the repulsive force of a spring. The design includes a permanent magnet armature secured to the valve, which enhances the efficiency of the injection process.
