Abstract:
A method, device and system for detecting and counteracting a runaway condition in a diesel engine system. The diesel engine system includes an inlet for supplying combustion air to a diesel engine, and an exhaust for relieving the diesel engine from exhaust gas. The diesel engine system further includes an exhaust gas recirculation system for selectively allowing exhaust gas from the exhaust to enter the inlet. A first gas flow path actuator is included in the exhaust gas recirculation system, and a second gas flow path actuator is included in the exhaust. The method, as performed by the system, comprises detection of an actual or potential runaway condition, and in response thereto deprives the diesel engine of oxygen. Depriving of oxygen is performed by opening the first gas flow path actuator and closing the second gas flow path actuator to cause stalling of the diesel engine. The depriving is accomplished by maximizing recirculation of exhaust gasses to the engine and increasing pressure drop over the exhaust for a first predetermined period of time.

Claim (Index 1):
Method for detecting and counteracting a runaway condition in an operator controlled diesel engine system, the method including:\n providing the diesel engine system including a diesel engine, an inlet for supplying combustion air to the diesel engine, an exhaust for relieving the diesel engine from exhaust gas, an exhaust gas recirculation system for selectively allowing exhaust gas from the exhaust to enter the inlet, and a first gas flow path actuator in the exhaust gas recirculation system; detecting an actual or potential engine runaway condition in the diesel engine system; and allowing an operator to effect stalling of the diesel engine in response to a detected actual or potential runaway condition by depriving the diesel engine of oxygen by opening the first gas flow path actuator for causing stalling of the diesel engine, the method further comprising: providing the diesel engine system further including a second gas flow path actuator in the exhaust, and enabling closing of the second gas flow path actuator in conjunction with opening of the first gas flow path actuator for contributing to stalling of the diesel engine, wherein depriving the diesel engine of oxygen is accomplished through:\n maximizing recirculation of exhaust gasses to the engine; and \n increasing pressure drop over the exhaust for a first predetermined period of time, and \n wherein the method comprises monitoring the diesel engine during, and after the first predetermined period of time for confirming if stalling of the engine has been accomplished.
