Ultrasonic Air Charger


Vacuum build-up in the inlet manifold during idle on most vehicles including turbo engine is around -50 kPa (-19.51bf/in sq). During overrun and light acceleration conditions in most normal aspirated and turbo engines, vacuum levels of up to -80 kPa (-31.21bf/in sq) can be expected.
During overrun with the throttle valve at say 10% open a vacuum of minus -75 kPa will cause 20% to 25% more air through the throat valve than a vacuum of -50 kPa. All of this is happening when the engine is not performing any work; i.e. driving downhill, slowing down to stop or whenever you are reducing sped for whatever reason. The end result is the gradual stopping of the engine known as “engine braking”.
The Ultrasonic Air-Charger makes use of the vacuum build-up in the induction manifold to create Ultrasonic vibration in the inducted air inside the induction manifold.This vibration, which is inaudible to the human ear ripples into the combustion chamber of the engine, as the air is being suck into the combustion chamber together with the energized fuel.

This vibrating air allows a more complete mixing of the air/fuel mixture, which enables as much air as possible to come into contact with the fuel droplets to cause a rapid burn rate of the fuel which will give rise to an even better and more complete combustion, making the engine more efficient. The Ultrasonic Air-Charger only works when the vacuum passes the -50 kPa mark or lower depending on its tuning and the engine’s characteristics.
For more complete air/fuel mixture, the best effect could be achieved by installing the Ultrasonic Air-Chargers at the three locations around the engine:
1) Crank-case Breather,
2) Charcoal Canister Breather/engine purge, and
3) Brake Booster.
