Background

A typical turbocharger is a device that utilizes exhaust gas exhaust power to drive a turbine wheel to rotate at high speed, thereby actively compressing gas to increase engine air intake, which is a flat compressed gas.

However, since the turbo-charging technique has a significant "lag response" in that the engine delays increasing or decreasing the output power due to the fact that the inertia of the impeller reacts slowly to the sudden change of the oil , and even after the reaction time is improved, it takes 1.7 seconds, so that the engine feels no engine power in case of a sudden acceleration in an emergency, and after the engine runs at a high speed for a long time, part of the oil is supplied to the turbocharger rotor bearing for lubrication and cooling, the oil pressure rapidly drops to zero after the running engine is suddenly stopped, the high temperature of the turbocharger turbine part is transferred to the middle, the heat in the bearing support case cannot be rapidly taken away, and the turbocharger rotor still rotates at a high speed due to the inertia, so that if the engine is suddenly stopped in a heat engine state, the oil retained in the turbocharger is overheated to damage the bearing and the shaft.
