A diesel engine is said to be in run-away mode when it runs out of control using an external fuel source and the operator cannot shut down the engine using conventional methods. During runaway, the engine damage can range from minor to catastrophic and this can cause enormous damage to the environment due to no emission control under these circumstances. In addition, an organization can incur financial losses due to loss of entire engine / engine components. In engine applications, such as power generation in an oil refinery, the oil mist can enter the intake stream of the engine and cause an engine runaway. In some of the OHW (Off Highway) and CV applications, the oil separator is connected to the intake system to have close-loop crankcase breathing system where in the engine oil may enter the combustion chamber through intake & the engine turns to run-away mode.
