Abstract
The present invention relates to an internal combustion engine provided with an optimized intake system. The engine derives from a traditional diesel cycle engine but is modified and optimized in its intake system to achieve performance superior to that of traditional diesel engines. According to the invention, some main characteristics of the timing system are modified to obtain, when required, a specific behavior of the intake valve lift curve. By operating in this way, it is possible to carry out an internal recirculation of the burnt gases, a reforming of the fuel (for example, from ammonia to hydrogen), a thermodynamic cycle similar to a Miller cycle.
