How Chemistry Controls Engine Design

摘要

A review of empirical engine data that exhibit the limits of the chemistry of fuel oxidation in engines is presented. These data have been compared to analyses using up to date fuel oxidation chemical analyses programs and shown to be in close agreement. The constraints caused by the fuel oxidation chemistry limitations are key determinants of the engine's overall design, determining allowed intake conditions, fuel-air ratios, compression ratio requirements, and the need for such ancillary devices as those for exhaust emissions aftertreatment.
