Diesel Engine Combustion Modeling

Computer-generated combustion models are essential for achieving low emissions while meeting other engine constraints such as maximum cylinder pressure, exhaust temperature, and compressor pressure ratio. Engineers use simulations in development programs that vary parameters such as:

Injection and valve timing
Valve overlap
Compression ratio
Boost pressure
Air/fuel ratio

Using the Southwest Research Institute (SwRI)-developed JETMIX code, engineers simulate diesel engine parameters such as:

Hole size
Injection pressure
Number of holes
Chamber density effects

Diesel Engine Combustion Design

To refine an existing engine or design a new engine, engineers use sophisticated solid modeling techniques to produce prototype components and assemblies, including:

Intake and exhaust ports
Manifolds
Piston bowls
Cylinder head assemblies
Complete engines
