Introduction: Diesel generators are vital backup power sources in facility management, ensuring seamless operations during outages. Proper maintenance, troubleshooting, and efficiency optimization enhance reliability and compliance with safety regulations. This guide covers essential best practices for diesel generator operation and preventive care to maximize performance. Diesel Generator Question & Answer 1. Why should a DG set not be run with full fuel in the tank? Answer: A full fuel tank creates improper pressure across fuel lines, leading to excessive black smoke emission. 2. Why is bleeding required? Answer: The fuel system requires air bleeding under the following circumstances: The engine has not been operated for a long time. A fuel element has been replaced. The engine was started without opening the fuel cock and has run for some time. The feed pump is not functioning properly. There is leakage from fuel pipes or fuel filters. 3. How to remove Air Lock? Answer: Air loc...

Introduction Fire is one of the most dangerous and destructive forces that can occur in homes, workplaces, and industrial settings. Understanding fire behavior, prevention techniques, and fire extinguishers is crucial for minimizing risks and ensuring safety. The Fire Triangle explains how flames sustain combustion through the presence of three essential elements: fuel, heat, and oxygen. Removing any of these elements can effectively control or extinguish a fire. Fire prevention and suppression methods focus on eliminating one or more of these factors. This article provides a detailed guide on fire control methods, fire prevention systems, and the types of fire extinguishers used for different classes of fires. Understanding the Fire Triangle The Fire Triangle is the foundation of fire science, consisting of three key components required for combustion: Fuel – Any material that can burn, such as wood, paper, gasoline, or chemicals. Heat – The energy source that raises the fuel's te...

Introduction Proper maintenance and operation of a diesel generator (DG) are essential for ensuring reliability, efficiency, and longevity. Incorrect handling can lead to engine damage, increased fuel consumption, and higher emissions. Following best practices helps in reducing breakdowns, optimizing performance, and ensuring safety. In this guide, we outline the most important Dos and Don'ts for operating a diesel generator efficiently. Dos: Best Practices for Diesel Generator Operation Idle the Engine Before Shutdown Always allow the engine to idle for 3 to 5 minutes before shutting down. This helps lubricating oil and coolant carry heat away from critical components like the combustion chamber, bearings, and shafts, preventing overheating and thermal shock. Monitor Oil Pressure The oil pressure gauge should display pressure within 15 seconds of starting. If oil pressure is not indicated within this time, shut off the engine immediately to prevent severe damage. Maintain Proper ...

Introduction Diesel generators (DGs) are essential backup power sources for industrial, commercial, and residential use. However, they contribute to air pollution by emitting NOx (Oxides of Nitrogen), CO (Carbon Monoxide), PM (Particulate Matter), NMHC (Non-Methane Hydrocarbons), and SO₂ (Sulfur Dioxide). To regulate these emissions and minimize environmental impact, various emission control standards have been established based on plant capacity, generator commissioning date, and area category. This blog post explores the emission limits for diesel generators, area classification, and the importance of adhering to regulatory norms to ensure compliance and environmental sustainability. Emission Standards for Diesel Generators The emission limits for diesel generators depend on the following key factors: Area Category: Category A - Municipal areas with a population of more than 10 lakh and up to 5 km beyond the municipal limits. Category B - Areas outside Category A, which are less den...

Introduction A diesel generator (DG) is an essential backup power source that automatically activates during grid failures, ensuring uninterrupted electricity supply. Operating a DG in AUTO mode simplifies the process by enabling automatic startup and shutdown based on power availability. Understanding the correct starting and stopping procedures ensures efficient performance, prevents malfunctions, and enhances the generator’s lifespan. Starting procedure for Diesel Generators in "AUTO" mode Follow these steps to start a diesel generator in AUTO mode: Check Emergency Stop Switch: Ensure the Emergency Stop switch on the DG panel is in the released (off) position. Set Selector Switch to "Remote" Mode: Switch the DG panel selector to "Remote" mode. Set ACB to Remote Mode: Ensure both the DG and EB Air Circuit Breakers (ACB) are set to "Remote" mode on the Main Distribution Board (MDB). Verify Lube Oil Level: Check that the lubrication oil lev...

Introduction Diesel generators are essential power sources that combine a diesel engine and an alternator to produce electricity. Whether for backup power or remote areas without grid access, these machines ensure uninterrupted electricity supply.  A turbocharger, crankcase ventilation system, and electronic control panel (ECP) are crucial components that enhance engine performance, efficiency, and reliability. Each plays a unique role, from boosting power output to maintaining engine balance and controlling fuel flow. Understanding these components helps in optimizing engine operation and longevity. Turbocharger A turbocharger is made up of two main sections: The turbine and the compressor.  The turbine consists of the turbine wheel and the turbine housing.  It is the job of the turbine housing to guide the exhaust gas into the turbine wheel. The energy from the exhaust gas turns the turbine wheel, and the gas then exits the turbine housing through an exhaust outlet area...
