Abstract: An apparatus of evaluating performance of a turbocharger with a pulsator is provided to test performance of the turbocharger in a manner as if the turbocharger is mounted on an actual engine by generating pulsating flow in compressed air introduced into a turbine unit. An apparatus of evaluating performance of a turbocharger with a pulsator includes inlet pipes(1), outlet pipes(2), a compressed air supply unit(3), temperature and pressure sensing units(4), flow sensing units(5), and a rotation number sensing unit(6). The inlet pipes and the outlet pipes are installed at inlets and outlets of a turbine unit(10) and a compressing unit(20). The compressed air supply unit supplies compressed air to the inlet pipe of the turbine unit by generating pulsating flow in the compressed air. The temperature and pressure sensing units are installed at the inlet pipes and the outlet pipes to sense temperatures and pressure at the inlets and the outlets of the turbine unit and the compressing unit and output sensing data to a control unit. The flow sensing units are installed at the outlet pipe of the turbine unit and the inlet pipe of the compressing unit to sense flow and output sensing data to the control unit. The rotation number sensing unit senses a rotation number of the turbocharger and outputs the sensed data to the control unit.

Abstract: PURPOSE: An EGR(Exhaust Gas Recirculation) system and an EGR rate measurement method are provided to measure an EGR rate accurately even in a transient driving state. CONSTITUTION: An EGR system comprises a first temperature sensor(2), a second temperature sensor(3), a third temperature sensor(4), and a controller(5). The first temperature sensor measures the temperature of intake air after passing through an intercooler installed in an intake pipe. The second temperature sensor measures the temperature of air flowing into an intake manifold after passing through the intake pipe and an EGR cooler. The third temperature sensor measures the temperature of exhaust gas recirculated from an exhaust manifold to the intake manifold after the recirculated exhaust gas passes through the EGR cooler. The controller collects the temperature and flow rate information from the temperature sensors and a flow sensor, calculates the calories of air passing through the intake manifold, the intercooler, and the EGR cooler, calculates the EGR rate by comparing the calorie at the intake manifold with the sum of the calculated calories, and controls an EGR valve according to the EGR rate.

Abstract: PURPOSE: An exhaust performance improvement method for a diesel engine using two-stage injection is provided to optimize the injection rate and enable application of HCCI(homogeneous charge compression ignition) combustion without a large modification of an engine. CONSTITUTION: An exhaust performance improvement method for a diesel engine using two-stage injection is as follows. First-stage injection is implemented to create pre-mixed gas at a crank angle of BDC(Bottom Dead Center) 60 degrees while maintaining low-temperature reaction in order to prevent the compressed air in a combustion chamber from reaching a diesel fuel ignition temperature of 750K before the completion of the injection. Second-stage injection is implemented after TDC(Top Dead Center). Accordingly, the compressed air temperature in the combustion chamber is reduced by the latent heat of vaporization generated in the first-stage injection and pre-mixing compression ignition is embodied through the ignition delay and injection delay of the second-stage injection.
Abstract translation: 目的：提供使用两级注射的柴油发动机的排气性能改进方法，以优化喷射速率，并且可以在不对发动机进行大修改的情况下应用HCCI（均质充气压缩点火）燃烧。 构成：使用两级注射的柴油发动机的排气性能改进方法如下。 实施第一阶段注入以在保持低温反应的同时在BDC（底死点）的曲柄角度下产生60度的预混合气体，以防止燃烧室中的压缩空气达到柴油燃料点火温度 750K之前注射完成。 TDC（Top Dead Center）后实施第二阶段注入。 因此，燃烧室中的压缩空气温度由于第一阶段喷射中产生的蒸发潜热而降低，并且通过第二阶段喷射的点火延迟和喷射延迟来实现预混合压缩点火。
