Abstract :
We consider the problem of reducing unburned tailpipe hydrocarbon (HC) emissions for internal combustion engines during the “cold start” period. Using Pareto-optimization, a cold start engine and catalyst model, the trade-offs between rapid catalyst “light-off” and reduction in unburned HC are analyzed. The effects of different operating constraints and catalyst light-off characteristics on the optimization results are also discussed
