The road profiles offer a good compromise between the various daily use needs of an automotive engine: regular minimum, good torque at a low rpm, low exhaust emissions and a significant increase in maximum power.
The profiles for racing use offer a substantial increase in power at high rpm, guaranteeing typical performance of a racing vehicle.
Some of the parameters on which action is taken to improve the performance of an internal combustion engine through camshafts with a new profile are the increase in the lift of the valves, the increase in the crossing values of the exhaust and intake valves and the duration of the cylinder filling phase. Through a correct design of a profile from the correct mix of these parameters, an improvement of the engine performance in relation to its use is obtained.
