SBIR-STTR Award

The Baker Opposed Piston Single Cylinder Engine is a 24 cu.in., 30 Hp engine with high power density (0.803 Hp/lb or 45.7 Hp/cu.ft.) capable of running on multiple fuels. The engine concept offers a totally new look at small engine development while utilizing several conventional engine components. In addition to high power density, the engine has significant advantages over current small engine programs, in both military and commercial applications. Previous development contracts have proven that the engine concept is viable and exciting. Now research is required to adapt the engine to the current military requirement for smaller applications and to advance the technology to a point where it will become a viable alternative. Specific primary areas of development that will be addressed in Phase I include: mechanical engine design, engine simulation/modeling, fuel research and component bench testing. Looking toward a Phase II SBIR, the objective will be to build and test a prototype of the 30 Hp engine.

The Baker Single Cylinder Opposed-piston Engine is a 24 cu.in., 30 Hp engine with high power density (0.642 Hp/lb or 35.7 Hp/cu.ft.) capable of running on multiple fuels. The engine concept offers a totally new look at small engine development while utilizing several conventional engine components. In addition to high power density, the engine has significant advantages over current small engine programs, in both military and commercial applications. Previous development contracts have proven that the Baker Opposed-piston Engine concept is both viable, and promising. The Phase I SBIR provided an opportunity to scale the existing technology down to a smaller size. The Phase II SBIR will allow development and testing of a small-scale (30 Hp) engine prototype, thus advancing the technology to new levels. This will be accomplished through detailed engine design using several COTS components, CFD and Zero-dimensional simulation, prototype fabrication, component bench testing, and engine testing.
