Nettet17. apr. 2024 · Increasing the intake lobe centerline from 104 to 106 degrees is considered retarding. All events will take place later in the engine cycle. Retarding the cam causes the intake valve to open and close later. This will reduce cylinder pressure which reduces the low speed performance of the engine. Nettet26. feb. 2016 · A lower intake valve lift increases air charge momentum passed the open valve. The increased velocity leads to enhanced fuel mixing and combustion. For added torque at a selected RPM keep the lift as low as possible without restricting the air charge. Ordinarily peak valve lift selection is not governed by partial load conditions.
