Introduction

Masashi Sagara, an accomplished inventor based in Osaka, Japan, holds a remarkable portfolio of 8 patents. His innovative contributions, particularly in the field of engine technology, have made significant impacts in the automotive and machinery industries.

Latest Patents

Among his latest inventions is an engine designed to enhance the cooling efficiency of a cylinder head in air-cooled engines. This invention incorporates a cooling fan connected to one end of the crankshaft, which directs cooling air to the cylinder head. The design features an intake manifold positioned above the cooling fan, with a duct placed centrally to intake air from an air cleaner. The cooling air is effectively channeled from both sides of the duct to the intake valve, exhaust valve, and injection nozzle situated in the cylinder head. Furthermore, a shielding plate is added to one lateral side of the duct to optimize airflow.

Another notable patent from Sagara is a sophisticated governor device. This device includes a first lever that connects a governor lever to a rotary speed setting lever in an interlocking manner. The second lever, which is pivotally supported by the first, connects to a third lever that is also pivotally attached and interacts with a governor weight. To enhance performance during low-speed rotations, a fuel injection compensation spring is placed between the first and second levers, enabling them to decrease rotary speed by a fixed amount. A compensation starting rotary speed setting device is integrated into the first lever, providing adjustable load changes for the fuel injection compensation spring.
