Abstract
A power system including an engine, an intake system, an exhaust system, and an EGR system. The intake system is coupled to the engine and receives a fresh intake gas, the fresh intake gas having a fresh intake gas pressure. The exhaust system is coupled to the engine and expels an exhaust gas, the exhaust gas having an exhaust gas pressure. The EGR system is positioned so as to couple the intake system and the exhaust system. The EGR system does not comprise an EGR cooler. The EGR system bypasses periodically a portion of the fresh intake gas around the engine, from the intake system to the exhaust system, when the fresh intake gas pressure is greater than the exhaust gas pressure.
