Increasing fuel economy and simultaneously reducing emissions is a permanent challenge for the engine designer. To solve this optimization problem in the best possible way, detailed insight is required into the complex chemistry-flow interactions that have a pronounced effect on fuel ignition and combustion behavior, and pollutant emission. To that end, ROTEXO's expert knowledge and COSILAB's unique detailed-chemistry software tools help reducing the number of costly and time-consuming test-rig investigations drastically. Thereby companies save precious development costs and time, and hence reduce the time-to-market for their products -- engines, exhaust systems, and catalysts.

Typical COSILAB applications of customers from automotive or engine industries include, for example,

• simulation of in-cylinder ignition and combustion,
• turbulence-chemistry interactions,
• effects of fuel additives or alternative fuels,
• auto-ignition and engine knock,
• computation of methane, octance and cetane numbers,
• calculation of flame speeds and burning velocities, and
• catalytic aftertreatment.
