Powertrain Systems

Delphi Marine Evaporative Emissions Canisters help limit the amount of gasoline vapors released into the environment by reducing evaporative emissions that can escape from fuel storage in boats with built-in fuel tanks. As the vapors enter the canister, hydrocarbon molecules in the vapors are attracted to, and stored on, the surfaces of the carbon bed inside the canister. The canister is then passively purged as fresh air is drawn toward it and the vapors are returned to the fuel tank, thus limiting the hydrocarbon exposure to the atmosphere.

Delphi offers a family of Marine Evaporative Emissions Canisters to meet specific customer requirements. They are shaped and sized for flexible hull mounting.

Benefits

• Help boat and hull builders and fuel tank manufacturers comply with U. S. Environmental Protection Agency (EPA) evaporative emissions standards
• Help manufacturers comply with recommendations and requirements by the American Boat and Yacht Council (ABYC) and the National Marine Manufacturers Association (NMMA)
• Canisters feature flexible mounting and compact packaging designs
• Plastic canister body enables various sizes, depending on application
• Marine-grade activated carbon achieves lower moisture adsorption compared with automotive carbon
• Mounting brackets allow movement of the bracket without stressing the canister body
  

Typical Applications

Delphi Marine Evaporative Emissions Canisters are tailored for gasoline powered boats with built-in fuel tanks.

Canister Sizing versus Fuel Tank Size
