Key words and definitionsKey words and definitions

• Water separation – exhaust system where the Water separation – exhaust system where the water is separated from the exhaust gas so water is separated from the exhaust gas so that the water can be discharged at or below that the water can be discharged at or below the water line and the gas above the water the water line and the gas above the water line. Of particular importance on generator line. Of particular importance on generator sets so that you don’t get the added noise of sets so that you don’t get the added noise of water splash.water splash.

• Backpressure – any restriction of the flow of Backpressure – any restriction of the flow of exhaust gasses through the exhaust system. exhaust gasses through the exhaust system. Important to consider the engine Important to consider the engine manufacturer’s recommendation for maximum manufacturer’s recommendation for maximum allowed when sizing an exhaust system.allowed when sizing an exhaust system.

Basic design principlesBasic design principles

• The role of a muffler in a wet exhaust The role of a muffler in a wet exhaust system is to conduct the products of system is to conduct the products of engine combustion – noise and engine combustion – noise and exhaust gas – overboard in a safe exhaust gas – overboard in a safe manner.manner.

• When addressing noise, there are When addressing noise, there are two types of mufflers – absorptive two types of mufflers – absorptive and reactive.and reactive.

• Absorptive mufflers depend Absorptive mufflers depend on substances to reduce on substances to reduce noise. In a wet exhaust noise. In a wet exhaust system that substance is system that substance is the induced water. All of the induced water. All of our mufflers are examples our mufflers are examples of absorptive mufflers.of absorptive mufflers.

• Reactive mufflers use a Reactive mufflers use a system whereby the sound system whereby the sound waves are reflected back waves are reflected back into the oncoming waves into the oncoming waves thus attenuating the noise. thus attenuating the noise.

Choosing the right exhaust Choosing the right exhaust solutionsolution

• Three important parameters to Three important parameters to consider: consider: – Engine LocationEngine Location– Exhaust system size (diameter)Exhaust system size (diameter)– Noise reductionNoise reduction

Page 12: Centek Exhaust Basics

Choosing the right exhaust Choosing the right exhaust solutionsolution

• Engine locationEngine location– Engines located at or below the LWL require some Engines located at or below the LWL require some

type of lift muffler. Engines located aft or mid ship type of lift muffler. Engines located aft or mid ship and above the LWL can utilize an inline mufflerand above the LWL can utilize an inline muffler

• Exhaust system sizeExhaust system size– Larger engines with higher horsepower require Larger engines with higher horsepower require

larger diameter exhaust and more space. larger diameter exhaust and more space. Backpressure can be an issue if the sizes are not Backpressure can be an issue if the sizes are not adequate.
