How Does a Diesel Generator Exhaust System Work?

The main function of a diesel generator exhaust system is to safely remove harmful gases produced during operation. As the engine burns fuel, it creates exhaust gases that must be vented out of the generator and away from people and equipment. The exhaust system consists of several parts, including the exhaust manifold, muffler, and exhaust pipe.

The exhaust manifold is a component that collects the exhaust gases as they exit the engine cylinders. From there, the gases pass through the muffler, which is designed to reduce noise levels and filter out matter. After passing through the muffler, the exhaust gases travel through the exhaust pipe and are directed outside.

Another important part of a diesel generator exhaust system is the use of a back pressure valve or butterfly valve. These valves are designed to regulate the flow of exhaust gases through the system, which can impact the generator’s performance. For example, a valve that is too restrictive can create pressure, which can reduce engine power and increase fuel consumption.

The exhaust system must be properly maintained to continue functioning properly.  Neglecting or overlooking the maintenance of the exhaust system can result in costly repairs and downtime, affecting your business’s operations.

Here are our top tips for keeping the health of your generator in check in between maintenance visits:

  • Undertake a visual inspection – Problems with your generator can be uncovered with a thorough visual inspection – check parts like hoses and belts for any leaks and signs of wear. Also check your fuel, oil, and coolant levels.
  • Use high quality fluids – Your generator will run best with high quality coolant, oil, and fuel. Avoid contaminants and build-up that interfere with a generator’s performance by choosing high-quality fluids and testing the fuel regularly to ensure it is not degrading.
  • Run your generator regularly – Low usage of your generator can cause wet stacking’ or build up in the engine exhaust and air in your fuel system, leading to damage to the internal parts of your generator. It’s important to run your generator regularly for a short period of time to avoid any issues.
  • Only use Original Equipment Management (OEM) parts – OEM parts, including air filters, fuel filters and oil filters that are endorsed by the generator manufacturer can extend the life expectancy of your diesel generator and provide a predictable expense for your business.
