Determining the right time to replace a generator can be a daunting task. A standby generator is one of those pieces of a business that feels useless. Kind of like a Contingency Plan. Until of course the power is out and it is the lifeline to keeping your business functioning or providing critical life safety functions. At CD & Power we are committed to helping you make the most informed decision for your particular requirements.
The first step is evaluating your current system. Trying to come to a consensus on the life of a generator/engine can be a real crap shoot. You can scour the internet and get a lot of different opinions. Here are a couple:
- Engine life for liquid-cooled 1800rpm engines can approach 20,000 hours if properly serviced depending on the application and environment
- Even 3600rpm diesel engines normally have a 10,000 to 12,000 hour life expectancy with proper maintenance and service.
- Diesel engines have a distinct advantage in longevity over their gasoline counterparts. Mechanical parts wear out over time due to the friction caused by parts rubbing together. Diesel engines, however, are engineered and built to be more robust due to the higher compression ratio in the combustion chamber and the high torque output they produce. Diesel engines also operate at lower speeds (rpm) than gasoline engines, which means the bearings, piston rings, cylinder walls, valve train, etc., don’t rub together as often. Engine speeds are often half that of a gasoline engine.
