Gasoline engines needs to reduce its negative emission waste and raise its thermal efficiency. Previous studies have shown an improvement of engines by regulating the ignition timing and retaining the engine at certain air-to-fuel ratio. Additional development of the thermal efficiency is anticipated by reducing the oscillation of pressure due to combustion (referred to as combustion ... https://www.lightemupsequences.com/limited-value-Icicles-No-6-Textured-Glass-Dildo-8-5in-Clear-Pink-mega-pick/
