PROPOSED IMPLEMENTATION OF PROTECTION SYSTEMS AGAINST DIESEL ENGINE FAILURE (DIESEL ENGINE RUNAWAY)

Abstract

When we mention power generation and locomotion, it is observed that the application of internal combustion engines is essential. In view of the large scale of application of these engines, in particular the compression-ignition engines, known as Diesel cycle engines, various problems inherent to the operation and maintenance of them are presented. One of the critical problems of the Diesel engine is a defect known as engine runaway. This problem occurs for several factors, but the lack of proper maintenance is the main reason. When the defect occurs there is no safe method of shutting down the diesel engine, generating loss of the motor and risk the human integrity is imminent. In this way, this article proposes a system of protection against engine firing using a system of locking valves. This system cuts the airflow at admission, causing the failure of the air to not allow combustion. The project was entirely developed in AutoCAD and presented only for theoretical reference requiring the implementation in the laboratory for conducting controlled trials.
