Computer Simulation of Intake and Exhaust Manifold Flow and Heat Transfer 860242

A complete non-steady intake and exhaust flow single cylinder computer simulation for spark ignition IC engines has been developed and is presented. The in-cylinder calculations include the use of a two-zone combustion model. The exhaust flow incorporated a quasi-steady heat transfer coefficient correlated from experimental data. Measurements from the experiment are compared to the results from the simulation. It was found that the quasi-steady heat transfer coefficient accurately models the temperature transients of the exhaust.
