Title: Masakichi Momono: Innovator in Internal Combustion Engine Technology

Introduction

Masakichi Momono is a notable inventor from Katsuta, Japan, recognized for his contributions to the field of internal combustion engine technology. With a total of 12 patents to his name, he has made significant advancements that enhance engine performance and efficiency.

Latest Patents

Among his latest innovations is an air intake equipment for internal combustion engines. This improved intake system prevents the formation of a liquid fuel film due to fuel deflection. It features multiple independent air intake pipes connected to a combustion chamber, allowing for efficient air introduction. The system includes collectors for distributing air and a throttle valve to control airflow. Additionally, a fuel supplying mechanism is integrated into the independent intake pipes to mix air and fuel effectively. A deflection mechanism is also included to ensure optimal air flow without undesirable fuel deflection.

Another significant patent is an intake system designed to uniformly distribute the fuel-air mixture within the cylinder. This system enhances ignitability during lean-burn operations by concentrating the mixture near the ignition plug. It produces tumble flow in the cylinder, accelerating combustion and reducing fuel consumption and exhaust emissions. The fuel is injected by a valve and atomized before entering the cylinder, while high-velocity air flow from bypass passages creates the necessary tumble flow.
