Exhaust system for snowmobile with gas combiner and airflow channel
A recently granted patent (Publication Number: US11927121B1) discloses an innovative exhaust system designed for snowmobiles. The exhaust system comprises a muffler housing with a muffler exhaust outlet, attachment brackets, and a muffler housing cover that creates an airflow channel. A gas combiner surrounding the muffler exhaust outlet receives air from the airflow channel and exhaust to emit a combined air-exhaust stream. The design aims to transfer heat away from the muffler housing by creating a reduced pressure region that pulls air through the airflow channel into the gas combiner.
Moreover, the patent also covers a snowmobile incorporating this exhaust system, where the muffler assembly is coupled to the forward frame assembly. The snowmobile design includes exterior body panels forming a forward internal compartment with air inlets that supply air to the airflow channel. Additionally, the muffler assembly features spacers to reinforce the airflow channel between the muffler housing cover and the sidewall. The unique configuration of the exhaust system and its integration into the snowmobile chassis highlight the focus on optimizing performance and heat management in snowmobile operations.
