Environmental psychology addresses environmental problems such as density and crowding, noise pollution, sub-standard living, and urban decay. 1  Noise increases environmental stress.
Hayapower is correct. The tube from the converter is for the smog pump (air injection) for the catalytic converter. The EGR tube comes off the passenger side exhaust manifold. Disconnecting the tube from the converter will not hurt if you remove the conveter and close off the tube end or leave it open.If you leave it open then at times you will hear a pumping sound from the tube caused by the smog pump when it reaches proper temperature.t's thermactor/secondary fresh air injected from the smog air pump for converter/catalyst secondary burn/conversion.. Disabling/restricting an EGR flow (drastically), can/will result in a DTC.. The tube is needed for a fresh air suppy to the converter..
Waste gasses from the motor contain harmful smog chemicals such as hydrocarbons, carbon monoxide and nitrogen oxides. It is the catalytic converterâs job to reduce these harmful emissions as much as possible in order to protect the air we breathe.The way that the catalytic converter functions is simple. It forces the exhaust gasses to come in contact with a chemical catalyst, in this case the metals platinum or palladium.The catalyst causes the gasses to quickly degrade into less harmful substances, like carbon dioxide and water.aste gasses from the motor contain harmful smog chemicals such as hydrocarbons, carbon monoxide and nitrogen oxides.
