The applied chemical engineering faculty of Kim Chaek University of Technology has recently developed a device that can effectively purify the exhaust fumes of motor vehicles.
With the increase of car and other means of transportation in the world, harmful ingredients in the exhaust fumes discharged by them are exerting harmful effect on life activities of humans and ecological environment.
Research has been conducted on a wide scale to purify the exhaust fumes of motor vehicles.
There are various ways for improving the quality of fuel and increasing combustion efficiency by rationally improving the structure of working organs and working environment.
“No matter how much the quality of fuel is improved or combustion efficiency is increased, it is impossible to fully remove the discharge of harmful ingredients like carbon monoxide. But the use of catalyser can purify almost all the harmful elements in exhaust fumes,” said developer Jong Song Chol.
Researchers conducted an experiment to verify application effect by using selective reduction catalyser which is a locally abundant material.
In the course of this, they thermodynamically stabilized the performance of catalyser and increased activity, irrespective of the rate of rotation of engine and load, in the way of coating porous carrier with catalyser material.
According to the results of dozens of rounds of running tests after installing the purifying device at petrol-engine motor vehicles, it almost got rid of harmful ingredients including carbon monoxide and nitrogen compound in the exhaust gas and increased the lifespan of catalyser over two times as compared to before.
