Abstract
This work presents a numerical analysis where the performance of an internal combustion engine of spark ignition is evaluated, using different camshafts to control the opening and closing of the intake valves of this thermal machine. The analysis was conducted only with the scope in the camshaft that control the intake valves. The authors believe that this has a greater influence on the performance of the engine, since, during the event of engine cycle exhaustion, the combustion products are under high pressure, so that they already have a natural tendency to outside the combustion chamber. At the end of the study, the results did not show any kind of benefit that justifies the change of the original camshaft of the engine for the others analyzed, but the results of the simulations help to understand a worldwide trend, which is the insertion of capable systems to control the opening and closing of the valves, simultaneously.
