Abstract:
A multi-cycle internal combustion engine having a head and block assembly defining a combustion chamber provided with an intake port and an associated intake valve for cyclically introducing an intake charge into the combustion chamber, the engine comprising:an electrically controlled driver affixed to the head and block assembly located relative to the intake port to excite the intake charge during an intake event causing the intake charge to be acoustically oscillated a plurality of times during the intake event at a frequency and energy level selected to optimize large scale recirculation patterns of the intake charge within the combustion chamber; andan electronic engine control regulating the operation of the internal combustion engine varying fuel flow and the driver as a function of engine operating conditions, wherein the electronic engine control varies the energy level of the driver as a function of engine speed and load.
