Abstract
A method and apparatus for boosting the pressure of the air charge to an internal combustion engine, which has an exhaust gas recirculation (EGR) system and a turbocharger. The EGR system is arranged to recirculate exhaust gas from an engine exhaust outlet passage to the engine air inlet passage. An exhaust gas bypass passage is arranged to divert exhaust gas that would otherwise reach the turbocharger's impeller. The engine has a single, unitary control valve with a valve inlet arranged to receive exhaust gas from the engine exhaust outlet passage, and three valve outlets. A first of the valve outlets provides exhaust gas to the EGR system for recirculation to the engine air inlet passage, a second of the valve outlets provides exhaust gas to the exhaust gas bypass passage and a third of the outlets provides exhaust gas to the impeller.
