Dynamic Surface Control of Engine Exhaust Hydrocarbons and Catalyst Temperature for Reduced Coldstart Emissions

  title={Dynamic Surface Control of Engine Exhaust Hydrocarbons and Catalyst Temperature for Reduced Coldstart Emissions},
  author={Pannag R. Sanketi and J. Carlos Zavala and J. Karl Hedrick},
Almost three quarters of the hydrocarbon (HC) emissions emitted by an automobile in a typical drive-cycle are produced during the first three minutes of its operation called the coldstart period. In this paper, we propose a way to decrease cold start emissions. A Model-Based paradigm is used to aid the generation of an efficient controller. The controller is built around a mean value engine model and a simplified catalyst model characterized by thermal dynamics, oxygen storage and static… CONTINUE READING
