Vehicle exhaust-gas purifier

A vehicle exhaust-gas purifier for purifying exhaust gases emitted from a vehicle having an engine and an exhaust pipe for the engine, comprising:

• an exhaust-gas gathering nozzle adapted for detachable connection to the exhaust pipe of the vehicle for gathering exhaust gases emitted from the vehicle;
• a filter chamber having a filter unit and an electrostatic dust collecting unit provided therein for removing any carbon particles and unburned fuel mist particles from the exhaust gases gathered through said exhaust-gas gathering nozzle;
• a catalyst chamber having a catalyst/activated-carbon layer provided therein for further purifying the exhaust-gases from which carbon particles and unburned fuel mist particles have been removed through said filter chamber;
• an introduction section connecting said exhaust-gas gathering nozzle and said filter chamber for introducing gathered exhaust gases into said filter chamber;
• and
• an emission section for emitting purified exhaust gases into environment;
• said vehicle exhaust-gas purifier is adapted for use while being directly connected to the exhaust pipe of the vehicle;
• said filter chamber and said catalyst chamber are disposed in a first line;
• said vehicle exhaust-gas purifier further compromises a cleaning chamber disposed in a second line different from said first line, said cleaning chamber comprising:
• an air nozzle for removing from said electrostatic dust collecting unit any carbon particles and unburned fuel accumulated on said electrostatic dust collecting unit;
• an oil separator for separating any oil from such carbon particles and unburned fuel which have been removed from electrostatic dust collecting unit;
• and
• a deodorizer for deodorizing any air including said carbon particles and unburned fuel which oil have been removed and flowing out of said cleaning chamber into environment;
• and
• said vehicle exhaust-gas purifier further comprises an electrostatic dust collecting-unit moving mechanism for moving said electrostatic dust collecting unit between a first position within said filter chamber and a second position within said cleaning chamber.
