A method for throttle progression control to minimize tip-in noise of an internal combustion engine by allowing the engine to receive only the required air for the commanded engine acceleration. The method comprises the steps of a) providing an electronically controlled throttle body and valve, b) providing an electronic control module, c) determining the engine air flow required to satisfy a desired engine acceleration, d) providing an input to the electronic control module corresponding to the engine air flow required, e) programming the electronic control module to limit the inflow of air during engine acceleration to match the engine air flow required for achieving said desired engine acceleration, and f) actuating the throttle body and valve to provide the limited air flow through the throttle body during the desired engine acceleration.
A system for controlling acceleration of an internal combustion engine to minimize tip-in noise, comprising:
A method for throttle progression control for acceleration of an internal combustion engine, said engine comprising a throttle body having a valve electronically controlled by an electronic control module, said valve being moveable between a closed position prior to engine acceleration and an open position during engine acceleration, said method comprising the steps of:
