Abstract: A compressor(s), mounted to any combustion engine, removes exhaust. The compressor is constructed of high temperature tolerant materials. The compressor is root, vain, pinwheel or screw design driven by belt, gear, hydraulic motor, crankshaft, camshaft, or pump. This compressor removes exhaust and gases by creation of vacuum on exhaust ports or manifolds. Vacuum is stored and maintained by the motion of the driven compressor. The process starts at the crankshaft, camshaft, or pump, spinning the compressor to create vacuum on one side and boost on the other. As exhaust valves open on any combustion engine of any fuel, exhaust must leave the engine. This compressor removes that exhaust through vacuum, cooling the exhaust, expediting the revolution of the engine and improving the combustion capabilities, increasing horsepower, torque, fuel consumption, cleanliness of exhaust. Using this compressor with any conventional turbo charger will eliminate turbo lag and improve intake levels.
