Abstract: PURPOSE: A variable catalyst device is provided to improve the efficiency of an engine by reducing the exhaust pressure of exhaust gas. CONSTITUTION: A bypass passage(42) is formed outside an MCC(Manifold type Catalyst Converter) catalyst(30) to pass exhaust gas into an exhaust manifold(12) without passing through the MCC catalyst. A partition(43) separates the entrances of the MCC catalyst and the bypass passage by forming in bypass holes(44,46) to pass the exhaust gas through the middle. A variable on valve(50) closes the bypass passage(44). The variable on valve permits the flowing of the exhaust gas through the bypass passage by opening when the temperature of the exhaust gas is raised. A variable pressure valve(60) closes the bypass hole(46). The variable pressure valve permits the flowing of the exhaust gas toward the bypass passage by opening when the pressure of the exhaust gas is raised. Thereby, the reduction of an engine output according to the exhaust pressure increase of an engine is prevented.
