Latest Patents
One of Utsugi's latest patents is a carburetor designed for internal combustion engines. This innovative carburetor minimizes the time delay in the engine's response to changes in the cross-sectional area of the air passage. It allows for a high level of freedom in selecting the communication cross-section area of the air passage and the air-fuel ratio based on the engine's load. The carburetor includes a fuel passage with a fuel nozzle for supplying fuel to the intake passage, a first air passage that communicates with the fuel passage, and a variable communication unit that can be moved between an open and closed position depending on the engine's load.
Another significant patent is a fuel supply device for engines. This apparatus is designed to be compact while allowing for a rapid increase in the amount of fuel in the air-fuel mixture in response to the operation of a throttle valve during rapid acceleration. The fuel supply apparatus features a fuel booster pump that introduces a portion of the air-fuel mixture into a negative-pressure chamber, which actuates the pump and facilitates the flow of fuel to the carburetor.
