Accurate Combustion Chemistry is Crucial to Engine Design

Designing new, high-efficiency, low-emissions IC engines presents technical challenges that are often dominated by the chemical kinetics that occur during combustion. Consequently, simulations of combustion for enhanced engine designs need good fuel-combustion chemistry. Modeling and simulation practices that were good enough for the design of yesterday's engines are insufficient for today's engines. Using old practices, the automotive industry often finds that combustion CFD is unable to predict values or even accurate trends in critical combustion behaviors such as ignition, flame propagation and emissions. This makes it tough to use simulation effectively to address the increased complexities in efficiency and emissions prediction.
