    摘要: To provide a novel power train system capable of improving fuel efficiency, reducing harmful components of an exhaust gas, and improving an output by adjusting a composition of a gas component of the exhaust gas in accordance with an operation condition. Therefore, provided is a power train system including a gas component separation unit (2) which extracts a plurality of gas components having different specific heat ratios from an exhaust gas of a spark ignition type internal combustion engine (1), a recirculation unit which recirculates the plurality of gas components to a combustion chamber of the internal combustion engine, and a ratio adjustment unit (3) which adjusts a ratio of the plurality of gas components recirculated to the combustion chamber in response to an operation state of the internal combustion engine. A composition of a gas recirculated to the internal combustion engine can be adjusted depending on various operation conditions. Accordingly, it is possible to improve fuel efficiency, reduce harmful components of an exhaust gas, and improve an output in a wide range of operation conditions of the internal combustion engine.

    摘要: Systems and methods for providing vacuum to one or more of a crankcase ventilation system, an emission control system, and an exhaust gas recirculation (EGR) system included in a turbocharged engine system are provided. In one example, approach, a method includes drawing vacuum from a vacuum source located in an intake of the engine downstream of a pre-compressor throttle and upstream of an intake throttle, and applying the drawn vacuum to a discharge outlet of a uni-directional crankcase ventilation system, where an inlet of the crankcase ventilation system is coupled to the intake of the engine upstream of the pre-compressor throttle.

    摘要: An engine system comprising an accelerator device which is operable to increase the amount of fuel delivered to the engine for combustion; an exhaust gas recirculation system for removing exhaust gas from the engine and recirculating a portion of the exhaust gas to the engine; and an oxygen delivery apparatus adapted to deliver oxygen to the engine in response to operation of the accelerator device. Using this system, performance losses from EGR can be abated by introducing compensatory oxygen.
