Abstract: A structural and combustion simulation of BN6V87QE gasoline engine is established based on GTPower software. And the matching for inlet manifold, valve timing, air-fuel ratio and ignition advance angle are simulated on the model. The experimental results have shown that the simulation is in good agreements with the original engine, the parameters of the BN6V87QE model is optimized and performances of the engine are improved.
