Abstract
A method of removing particulate and other materials from the exhaust gases from an internal combustion engine in which the exhaust gas is passed through a bed of charged ferro-electric materials. Three forms of apparatus for carrying out the method are described.
Claims16
A reactor for reducing exhaust emissions from internal combustion engines, comprising a reactor chamber adapted to form part of an internal combustion engine exhaust system, wherein the reactor chamber includes an active element through which in use exhaust gases are constrained to pass consisting of a body of pellets of a heat resistant material having a high dielectric constant and at least one pair of electrodes by means of which the pellets within the active element can be charged electrically.
A method of reducing exhaust gas emissions from an internal combustion engine, wherein there is included the operations of passing exhaust gases from an internal combustion engine through a reactor chamber including an active element consisting of a gas permeable body of pellets of a heat-resistant material having a high dielectric constant and applying an electric potential of the order of tens of kilovolts to the pellets in the active element so as to cause the removal from the exhaust gases of carbonaceous components of the exhaust gases.
