<p>A turbocharger protecting method of an engine provided with an LP-EGR including an engine, a turbocharger disposed downstream of the engine, an exhaust gas post processing device disposed downstream of the turbocharger, an LP-EGR (low pressure exhaust gas recirculation) valve disposed downstream of the exhaust gas post processing device, an LP-EGR cooler disposed downstream of the LP-EGR valve, and an air supply line connecting downstream of the LP-EGR cooler and a compressor of the turbocharger, the turbocharger protecting method includes predetermining compressor inlet limiting temperature, estimating compressor inlet temperature and comparing the estimated compressor inlet temperature and the predetermined compressor inlet limiting temperature, and lowering the compressor inlet temperature if the estimated compressor inlet temperature excesses the predetermined compressor inlet limiting temperature.</p> |
