Abstract: PURPOSE: A supercharging and EGR(exhaust gas recirculation) pipe system for an internal combustion engine is provided to maintain the low pressure and temperature of an intake pipe. CONSTITUTION: A supercharging and EGR(exhaust gas recirculation) pipe system for an internal combustion engine comprises a turbo-supercharger(30), an EGR unit(40), and a flow path. The turbo-supercharger is composed of a turbine(10) and a compressor(20). An EGR valve(42) is attached on the EGR unit and re-circulates exhaust gas exhausted from an engine. The flow path sends the exhaust gas exhausted from the engine to the front of the compressor through an EGR cooler(44) of the EGR unit. The flow path sends exhaust gas for supercharging to the turbine of the turbo-supercharger.

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.
