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 of these parameters and their subsequent optimization for a target design will be numerically assessed through development of a Virtual DBRE Simulation tool, or VDBRES.
Three succinct stages will be deployed in the development and
commercialization DBR technology:
1) Hydraulic
2) Pneumatic
3) Engine
Each phase has established benchmarks which will be
demonstrated by successful prototypes of commercial products.
The information gathered from each phase will be instrumental
in justifing and completing the following phase.
Extensive computer modeling and analysis will be leveraged
to ensure optimal performance while minimizing development time and
cost.
1) Hydraulics
It is anticipated that the hydraulic phase can be done rapidly with few
departures from current designs. This will confirm volumetric
efficiency, fluid dynamics and sealing issues.
2) Pneumatics
The pneumatic phase will begin the use of simulation tools for
optimization of flow with compressible fluids. High speed seals, and
lubrication requirements will be investigated in prototype compressors,
turbochargers and vacuum pumps (having the unique ability to function
in both series or parallel as required.)
3) Engine
The virtual modeling work done in the prior phase will be the basis of
intense refinement for the engine phase. Detailed description of this
is in the DBRE Engine Development and Work Plan proposed by
TECAT Engineering.
Essentially the best way to get further and faster. Once the virtual
model is refined, all the variables can be manipulated to literally
‘make’ hundreds of engines in a month to optimize
performance.
The results of this are direct engineering with a high degree of
accuracy predicting results.
