ABSTRACT:
Disclosed herein is an emergency shutdown mechanism for a turbocharged diesel locomotive to prevent overspeeding of the turbocharger under engine malfunction conditions. The shutdown mechanism includes an air flow shutoff plate slidably mounted for selective closing of the air intake end of the turbocharger, a plurality of sensors mounted in the air box about the pistons for detecting increases of temperature and/or pressure within the air box and means activated by the sensors in response to such increases of temperature and/or pressure for moving the shutoff plate across the air intake end of the turbocharger and preventing air flow therethrough. The cessation of air flow through the turbocharger causes the engine to immediately shutdown and prevents overspeeding of the turbocharger.
