A diesel generator that produces black smoke during starting is typically experiencing incomplete fuel combustion caused by either excessive fuel delivery relative to available air, restricted air intake from a dirty air filter, or incomplete atomization of fuel from worn or malfunctioning injectors. This black smoke — composed primarily of […]

Checking the diesel generator coolant level safely requires waiting for the engine to cool below 50°C (122°F), wearing appropriate personal protective equipment including insulated gloves and safety glasses, and inspecting the coolant expansion tank or radiator filler neck to verify that the level sits between the minimum and maximum marks

The ideal diesel generator storage humidity level for units placed in long-term storage is a relative humidity (RH) abaixo 50%, with a recommended range of 30–50% RH to prevent corrosion of electrical connections, oxidation of engine internals, and moisture ingress into insulation systems. Excessive diesel generator humidity during storage accelerates

When a diesel generator is stopped abruptly through its emergency stop (ESTOP) função, o motor, governor, sistema de excitação, and protective relays all require a systematic reset procedure before the unit can be safely restarted. A proper post-emergency-shutdown diesel generator reset sequence protects both personnel and equipment from the hazards of
