AMW - One approach to success

The DBRE engine concept promises significant improvements in engine performance, fuel economy and NVH over conventional reciprocating engine designs. Manipulation of its unique design parameters allows for a variety of engine geometries and performance characteristics. The relative interaction and optimization of these parameters for a target design will be numerically assessed through development of a Virtual DBRE Simulation tool, or VDBRES.

Three precise phases will be deployed to develop and commercialize DBR technology:
        1) Hydraulics
        2) Pneumatics
        3) Engine

The goal is to build prototypes of commercial products and compare them with benchmarks that have been established for each phase. Each prototype in itself has the potential to be a viable product. The information gathered from each phase will be instrumental in justifying and completing the subsequent phase. Extensive computer modeling and analysis will be done to ensure optimal performance while minimizing development time and cost.

1) Hydraulics
The hydraulics phase is expected to be brisk and will extensively leverage current designs. This phase will address volumetric efficiency, fluid dynamics and sealing issues.

2) Pneumatics
The pneumatics phase will use simulation tools to optimize the flow of compressible fluids. High speed seals and lubrication requirements will be investigated in prototype compressors, turbochargers and vacuum pumps. 

3) Engine
The modeling in the previous stage will be the foundation for intense refinement in the engine phase. Detailed description of this can be found in the DBRE Engine Development and Work Plan proposed by TECAT Engineering.

Once the computer model is refined, all the variables can be manipulated to literally ‘make’ hundreds of engines in a month to optimize performance. From this, several candidates will be selected for further refinement, prototyping and testing. This direct engineering approach will ensure a high degree of accuracy in predicting results.
