An exhaust gas liquefying device is provided for reducing pollution from vehicles includes a casing generally comprised of two interconnected chambers. The casing is attached to the rear portion of a vehicle such as a car or small truck. The casing has an entry port to collect the exhaust gas from an exhaust pipe coming from the vehicle. At least one fan provides additional air and a condenser coil cools down the exhaust gas into a liquid which precipitates the carbon in the carbon dioxide. The added ambient air provided by the fan helps in evaporating the liquid which exits from an evacuation port.

An exhaust gas duct system for an internal combustion engine includes an upstream, first exhaust gas pipe area (30), a downstream, second exhaust gas pipe area (34) adjoining the first exhaust gas pipe area (30) in a transition area (38) in an exhaust gas flow direction (G), and a liquid drain channel area (60) in the transition area. The drain channel area is open from the exhaust gas flow volume (78) in the first exhaust gas pipe area (30) or/and in the second exhaust gas pipe area (34) to a liquid collection volume (80).

A catalytic converter includes at least one heating element that is configured to disrupt the direction of flow of exhaust gases which contain harmful toxic gases and pollutants and aid in removing and/or reducing said toxic gases and pollutants.

An exhaust system that includes a catalytic converter, selective catalytic reduction system, a muffler and, for certain applications, a diesel particulate filter that each include at least one filter that has an electric heating element, a metallic coating and a plurality of metal rods extending therethrough. The combination of elements are configured to heat the internal housings of the exhaust system and disrupt the direction of flow of exhaust gases which contain harmful toxic gases and pollutants and aid in removing and/or reducing said toxic gases and pollutants.

The invention relates to an air cleaner for a vehicle which can be installed on the rear of the vehicle, which includes a suction pipe provided with a slit having a length corresponding to a width of the vehicle, an air pump connected to inside of the suction pipe by a guide pipe, and a filter means connected to the air pump. The air cleaner is operated in a way of sucking exhaust gas and fine dust generated from an exhaust line of the vehicle together with fine dust and dust particles generated around tires of the vehicle during driving of the vehicle, removing them, and then discharging purified air to the atmosphere. The air cleaner can effectively remove the fine dust and various-shaped dust particles directly and indirectly generated from the vehicle, and remarkably reduce generation of fine dust by considerably suppressing diffusion of fine dust into atmosphere.
