Title: Innovations by Yasuo Sunaga
Introduction
Yasuo Sunaga is a notable inventor based in Koga, Japan. He has made significant contributions to the field of internal combustion engines, holding a total of five patents. His work focuses on enhancing the efficiency and functionality of air-intake systems.
Latest Patents
One of his latest patents is an innovative air-intake manifold designed for internal combustion engines. This manifold includes a plurality of air-intake pipes that connect between a collector and an air-intake pipe mount. Each air-intake pipe is uniquely bent to achieve a predetermined shape. The design involves fabricating the air-intake pipes from a substantially straight double metal pipe, which consists of an outer pipe and an inner pipe. The clearance between these pipes is equal to or less than 0.2 mm, allowing them to locally contact each other at an intermediate region. This design creates an air layer with a thickness of about 0.2 mm, enhancing the performance of the intake system.
Another patent involves an intake manifold that features multiple branch tubes. These tubes are joined by brazing in a furnace at one end to a flange on the engine side and at the other end to a surge tank on the throttle chamber side. The surge tank is divided into two components: a brazing side member and a non-heating side member. The branch tubes are secured in position relative to the brazing side member through peen locking and are subsequently joined by brazing. The non-heating side member is attached to the brazing side member using bolts, ensuring a robust assembly.
