Abstract
An internal combustion engine having a turbo-supercharger and a catalytic exhaust gas purifying device located downstream of the exhaust gas turbine. The exhaust passage is provided with a bypass passage in parallel with the exhaust gas turbine and a valve is provided for opening the bypass passage when the engine operating temperature is below a predetermined value so that the exhaust gas is passed through the bypass passage to the catalytic device. This arrangement is effective to heat the catalytic device rapidly to a working temperature.
