Cummins C3000, model QSK95
4-step process of a basic combustion engine
intake, compression, power, exhaust
What are the 4 main sections of a Standby Generator? Describe the general function of each.
Alternator - converts mechanical energy from the engine into electrical energy
Engine – the “prime mover” that provides the mechanical energy (rotation) that drives the alternator, which then converts that mechanical energy into electrical energy
Radiator – cools the engine as it runs to prevent overheating
Exhaust - collect gases from the engine, remove harmful toxins from those gases
Describe the purpose of a standby generator, as it pertains to our system, to include:
The purpose of a standby generator is to provide power to our electrical system should the utility power fail.
Describe, using pictures or words, how a drop of fuel is converted into electrical energy.
Diesel Fuel goes to cylinder -> Combustion occurs in cylinders -> Piston moves -> Crankshaft rotates -> Alternator spins (rotor spins inside of stator) -> Magnetic field generated -> A/C electricity produced
Assuming our Generator fuel tank is at Full (90%) capacity, how long can a single generator continuously operate before running out of fuel?
