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..
But if your MAP sensor is your buddy, your exhaust gas recirculation (EGR) valve is the bully with the huge forehead who stole your lunch money and pantsâd you in front of the cheerleaders. In a gasser, EGR isnât too obnoxious because gas engines donât create much soot. But in a diesel, well, weâre sure we donât need to tell you about all the gritty, dirty carbon that little EGR bully throws back through your intake, cylinder head(s), and combustion chamber.
