Each engine and each operating location requires a unique combination of silencer properties. For this reason, many different silencer models are cataloged to cover most silencing problems. In cases where standard silencers do not meet a particular need, special silencers can be designed. For the majority of engines and operating conditions, multi-chamber silencers provide maximum noise attenuation within acceptable back pressure limits. Most naturally aspirated and supercharged engines need this type of silencer, and many turbocharged engines are best silenced with this design.
Some engines require very low exhaust system back pressures for maximum engine performance.
Many turbocharged engines and some naturally aspirated engines fall into this category. For these engines, straight-through, reactive silencers are available to provide adequate silencing while imposing negligible restriction on the flow of exhaust gas. Spark-arresting Silencers Operating locations exist where fire hazards and safety codes require removal of sparks from exhaust gases. Our spark arrester silencers are engineered to perform the dual function of spark arrest and silencing for all internal combustion engines. All rights reserved.
