Design of Westgate Controller for Performance Improvement (Case Study: Allen Diesel Engine 4012)

Abstract

Westgate is a gate placed in the path of exhaust gases after combustion and before the arrival of these gases to the compressor. This gate is used to reduce the exhaust air that drives the air compressor due to several variables: pressure, temperature, and speed of the machine. All these variables vary according to the load of the engine. In this thesis, the gate is used to eliminate the surplus on the engine. Several simulation tests are performed to evaluate the performance of the proposed system. The problem is Allen Diesel Engine 4012 that fuel consumption is more than required, that makes excessive exhaust gasses and black smoke, which makes air contamination and that adversely affect the performance. The solution to solve this problem is by adding westgate to exhaust system. In this thesis a simulation system is created after adding westgate. The simulation results show that the performance of the proposed system is good under different optional conditions
