How is the hydroxy injected into the engine?
The hose coming from the water trap is connected to the air intake before the air breather, so that the gases introduced into the intake are first filtered by the air filter. We are not interested in a vacuum because the manifold has greatest vacuum at the wrong time, and no vacuum at the worse time. Also, we want the hydroxy gas filtered of any mist, which may carry traces of electrolyte. As an additional benefit, the air filter serves as a first line of defence protecting against a backflash coming from the engine.
