Because of the high RPMS ( ~200,000 RPM) the bearing which holds the turbine gets superhot and even the lubrication gets very hot. The only wat the ball bearings ( ceramic or steel) can cool down is from the oil it feeds directly from the oil sump of the crank. while the engine is running the oil is circulating through the inlet to the ball bearings fed by the oil pump. when you suddenly stop the engine after a hard run, the bearings are still super hot and not yet cooled down and the oil supply is cut off - no cooling. Prolonged abuse of the bearings will burn the bearings and cause turbo failure. This is the reason why it is advised to keep the engine running so that the turbo bearings are fed with oil from the oil pump. The engine should be running for the oil pump to work. To over come this problem, turbo timers are available which keep the engine running for specified amount of time even if you lock and leave.. the turbo timer runs the engine and switches the engine OFF after the specified time. thus keeping the turbo bearings lubricated and cool. |
