Web22 jul. 2013 · Dial-A-Jet is an acoustical device that is triggered by acoustic sound signals. The acoustic signal is generated when gasoline is ignited in the cylinder just inches away from the Dial-A-Jet. This signal amplifies the pumping action created by the reversionary pulse waves that occur naturally in any engine’s intake tract.
