Engine Design and Analysis
Southwest Research Institute® (SwRI®) has more than three decades of experience in engine design and analysis that includes:
• “Clean sheet” engine design from concept to production release
• Engine upgrades or conversions for increased power, improved fuel economy, and reduced emissions
• Vehicle integration
• Design reviews
• Product and process troubleshooting
• Technology transfer
• On-road, off-road, light-duty through high horsepower
SwRI engineers use a variety of sophisticated tools and techniques in a production-centered approach to evaluation and development of unique engine concepts, analyses of engines and engine components, and problem-solving.
SwRI’s engine design team has specialized expertise gained through work for more than a dozen engine manufacturers. The results are robust, low-friction engine designs based on experience with support from simulation and analysis software, produced with very short cycle times.
The team has extensive expertise in applying computer-aided engineering (CAE) tools for production intent as well as research-oriented designs. The following CAE analysis techniques are applied in the design process for components, engines, drivetrains, and vehicle subsystems:
• Solid modeling/computer-aided design (CAD)
• Engine performance simulation
• Finite element analysis (FEA)
• Classical analysis
• Dynamic system simulation
• Computational fluid dynamics (CFD)
• Fluid flow system simulation
• Probabilistic reliability
• Fatigue and life prediction
• Noise, vibration, and harshness (NVH)
• Rapid prototyping and tooling
SwRI engineers use 3-D parametric CAD modeling and an experience-based analysis approach to design production-quality clean sheet engines.

SwRI engineers use computational fluid dynamics to analyze coolant flow through a cylinder head water jacket to predict temperatures in solid models. Combined with FEA, relative analysis, and proprietary design guidelines, this technique is used to ensure structural durability.
SwRI maintains a specialized facility for noise source and signal analysis, model-based simulation, structural dynamics, and sound quality evaluation.

Mechanical SimulationSimulation is performed by experienced staff with an understanding of con-straints often imposed by manufacturing parameters. To simulate the kinematic and dynamic performance of engine mechanisms, SwRI engineers balance technological solutions with practical experience in their approach to client proj-ects. Analyses can be performed independently or coupled with parametric solid modeling, finite element analysis, tribology, and cycle simulation software.
Noise, Vibration, and HarshnessSwRI engineers use established and evolving techniques to design quiet engines. Our globally recognized staff has extensive experience in engine noise evaluation and assessment, source and path evaluation, as well as component design and remedial action to suppress noise.
Probabilistic ReliabilityIn an effort to develop faster, better, and more cost-effective ways to design, manufacture, and maintain engine systems, SwRI engineers have pioneered the integration of advanced reliability methods and failure models.
Rapid PrototypingRapid prototyping (RP) is used to create production-intent hardware suitable for engine development testing while production tooling is being developed. This can substantially improve total time to market and reduce product development costs.
SwRI’s in-house RP capabilities include direct computer numerically controlled (CNC) machining and a fused deposition modeler (FDM) machine that builds models in ABS plastic. A selective laser sintering (SLS) machine is also available to model in different materials at higher speeds.
