Abstract
A catalytic converter includes a channel for conducting a gas flow forwardly in a longitudinal direction. The channel is coated with a catalyst and has at least first and second turbulence generators spaced apart in the longitudinal direction for making the gas flow turbulent. Each turbulence generator includes a rear face inclined forwardly at an angle of from 35 to 60° from a base of the channel and facing rearwardly, a connecting face extending forwardly from a free edge of the rear face and a front face projecting toward the base from a front edge of the connecting face and facing forwardly. The first turbulence generator is disposed closer to an inlet of the channel than the second turbulence generator. A longitudinal center of the first turbulence generator is spaced longitudinally from the channel inlet by a distance, which is a function of the hydraulic diameter of the channel, the Reynold's number, and the Schmidt's number 1 of the gas.
