Operation and Maintenance of Diesel Generators – Part 4: Understanding Fuel System and Air System of Diesel Generators
Part 4: Understanding Fuel System and Air System of Diesel Generators A diesel generator (DG) set relies on multiple interdependent subsystems to ensure optimal performance, fuel efficiency, and power generation. Among these, the fuel system and air system play crucial roles in maintaining engine efficiency and ensuring complete combustion. The fuel system ensures that the correct amount of diesel is delivered at the right time and in the proper condition, while the air system is responsible for supplying fresh air for combustion and efficiently expelling exhaust gases. Without these systems functioning properly, a generator may suffer from power loss, excessive emissions, and reduced efficiency. In this fourth part of the Diesel Generator Insights Series, we will explore the fuel system and air system, their key components, functions, and maintenance best practices. In the next part (Part 5), we will focus on the Cooling System, which plays an essential role in preventing overhe...
