Butanol/Gasoline Test Plan
Abstract
This Test Plan was developed to demonstrate the feasibility of using an alternative fuel in USCG gasoline-powered boats. A blend of 16.1 percent biobutanol and gasoline (BU16) was selected as the test fuel and a USCG 25 Response Boat-Small (RB-S) with Honda Marine outboard gasoline engines and a 38 Special Craft-Training Boat (SPC-TB) with Mercury Marine outboard gasoline engines were chosen as the demonstration boats. Testing consists of four phases: materials, bench, field, and operational testing. Materials testing will ensure all components in the engine and fuel system are compatible with BU16. Bench testing will ensure the engines operate satisfactorily on BU16. Field testing will ensure there are no problems with using BU16 on the USCG boats prior to operational testing. Operational testing will ensure there are no problems with using BU16 on the test boats over an extended period that encompasses typical operational and environmental factors. Prior to commencing field testing, the RB-S and SPC-TB engines and fuel systems will be modified in accordance with a Time Compliance Technical Order (TCTO) to ensure compatibility with BU16.
