A Kirloskar diesel generator works by using diesel fuel to run an engine. This engine turns a part called an alternator, which then makes electricity. The process starts when the generator is turned on, either manually or automatically when power fails. The generator keeps running until regular electricity comes back. It has parts that control the voltage and keep the output steady. Understanding how it works helps in better use, safer operation, and easier troubleshooting. This also allows users to take proper care of the machine, leading to fewer breakdowns and more reliable power during blackouts.
