Encased Exhaust

Abstract

The encased exhaust is a traditional aftermarket expansion chamber muffler system for a two stroke engine encompassing a duct fan/propeller. The propeller is mounted directly to the engine's driveshaft, eliminating reduction gears and belts allowing for more airflow and less weight. This eliminates the muffler and replaces the cage on a paramotor, allowing for more airflow through the funneled air duct. The configuration of these two functions exists but not in this sequence, that is what makes this product unique.

Claims

1. The encased exhaust is an exhaust propulsion system which replaces the traditional exhaust system

2. It eliminates the muffler and replaces the propeller cage on a paramotor, allowing for more airflow through the funneled air duct

3. The encased exhaust can be used in RC planes and drones

DETAILED DESCRIPTION OF THE INVENTION

[0011] The expansion chamber stages consist of separate pieces of sheet metal formed in an arc shaped bend. These sheet metal sections are welded together at the inlet and outlet sides of the cylinder's ducting, and at the end and beginning of each stage. The inner liner/sleeve/ducting cylinder is welded to the outer sleeve/shell, creating a chamber. They all funnell air flow. The entire cylinder is the bottom of the expansion chamber stages. The width of the sheet metal changes according to the different number of the expansion chamber stages. The propeller is mounted directly to the engine's driveshaft, eliminating reduction gears and belts allowing for more airflow and less weight. The propeller's diameter determines the stages' combined radius. The engine's header connects to the divergent cone.
