Latest Patents

Hiramatsu holds a patent for a "Device for controlling evaporative emission from a fuel tank." This apparatus is designed to treat fuel vapor in motor vehicle fuel tanks by utilizing adsorption treatment. The invention includes a fuel tank with a partitioning wall that creates a small fuel storage chamber. Within this chamber, a canister container is housed, which stores a fuel adsorbing material. During fuel feeding, the introduced fuel cools the canister container. Conversely, when the engine operates, high-temperature return fuel heats the canister container, promoting the adsorbing and de-adsorbing action of fuel by the adsorbing material. This innovative design helps prevent direct emissions of fuel vapor into the atmosphere.
